I did a project on european eels when I was at uni, back in 2017. Eel migration was still a bit of a mystery then, we literally had an eel expert in to answer questions and most of his answers were "we don't know yet". Cool to hear that 5-6 years later, a little more of the mystery has been solved!
We've known the general "the come from near the Sargasso" for around a century though. Some European scientist got a bunch of ship captains to periodically let down nets, and send him the catch and the location so he could do a survey of what was going through which sections of the Atlantic. The conclusion (after sifting through several years of results) was the determination that their spawning grounds are in the Sargasso. They were recently caught _on film,_ but that's about it. We've known where European Eels come from for around a century.
nevermind the larval stage - adult eels go from living 25+ years in freshwater, migrating kilometers over land when it rains (you forgot to mention that part) to all sorts of ponds and lakes not even connected to the ocean to migrating back through the ocean at depths of up to 1400m?! goddamn that's a crazy fish! also that ~25 year age minimum for breeding, and spawning just one time before dying, explains my confusion about hearing that european eels are nowadays considered to be a highly threatened species [edit: IUCN critically endangered, the closest category to extinction] after previously being one of the most common and cheap fish everybody took for granted. 😬 I think we have a passenger fish situation on our hands. though in terms of reproduction, it's more like whaling or fishing greenland sharks.
Technically CR (Critically Endangered) is the second closest category to Extinct, not the closest. Extinct in the Wild is the category between CR and E. I work with CR species in the wild and have had to write up some of the IUCN species descriptions.
According to naturalist Gerald Durrell, elvers (the stage of young eel that migrates from the ocean back to inland waters) don't just migrate over land when it rains -- he tells of seeing columns of the little critters writhing their way over the dusty ground on the Greek island of Corfu on a dry sunny day when he was a boy.
Hi! Marine biologist/zoologist here. We have seen eels travel to the Sargasso Sea en masse once a year and then baby eels swim back to the freshwater systems they grow up in. But because science is science, it can't be stated as mystery solved until the spawning behavior is witnessed in real time.
Science isn't a collection of unassailable facts. It's a method. Some things can be safely extrapolated, some cannot. Science has discovered a great deal about and solved quite a few mysteries about say, black holes, without directly observing specific phenomenon. The effect the phenomenon had combined with other direct observations led to a discovery with no direct observations. If black holes interest you I'd suggest looking them up, there's too much to go into here. My point is, you're sort of correct, but not empirically.
Hi marine biologist/ zoologist, I'm somebody also interested in the field and just recently did an internship at an aquarium here in Finland, which, coincidentally, happens to be the only place in the world where a yellow eel has turned into a silver eel naturally, or well, spontaneously. I managed to watch as scientist from the Netherlands weighed, drew blood, did ultrasounds and measured some of the eels at the aquarium. So maybe, in the future, they might spot the signs of an eel turning silver! And then impregnate that eel with sperm from male eels from the research lab for eels in the Netherlands. So we might see the whole process soon! Hopefully, of course! Then science can't say that it's still a mystery lol (Yes the eel mamas were quite big haha, the scientists let me handle one of the specimens, very cool experience. Would recommend eel touching at least once in your marine biologist life!)
@@_klc_ When a marine biologist / zoologist says, it's a must to touch a eel, it's ok but when I tell woman it's fun to touch my yellow eel, they call it seksual harassment. ☹
@@sbtig9637 I know I'm not OP, but just wanted to reply to this! They are tasty, they are indeed, but at least here in the Baltic sea the population is dying. If we don't research how they reproduce, the eels we know and love (even by their taste, yes) will be gone
There's a phenomenal book by Patrik Svensson called "Ålevangeliet" ("The Eel Gospels") that studies the murky and enigmatic nature and history of eels. It tells the tale of the Sargasso migration told about in this video, but also chronicles mankind's attempt to locate their genitalia (Sigmund Freud studied eels for years in his youth; the book strongly hints that his later frustrations derive from his failure to locate eel genitalia), and how eels that are stuck in earlier states of being (such as as yellow eels) kind of seem to not age, like at all, over literal decades. The book has also been turned into an opera.
I will never understand why things that have no flavor become "delicacies". Shark fin is like this too, and even worse. Fishers catch them, hack the fins off, and leave them to die. It devastates shark populations. Shark fin is flavorless and the texture is weird, and yet it's still considered a delicacy and a status symbol.
Because humans are gullible. Slap the word delicacy onto anything and it becomes "special" and exclusively for the wealthy. Then classist fools fall for the specialness of the delicacy and pay ridiculous amounts of money for it without using their brains. We may be great apes, but so much of our behavior is still "monkey see, monkey do."
Cause they are rare or expensive ig. Kinda like how lobsters or black caviar were the poor person's food in the past due to being abundant, but got fished so much that now they are a delicacy ig.
Able to spend money on expensive, pointless things. Is part of showing off their wealth. Most people will be respectful and not tell the emperor he is not wearing clothes.
I feel like part of it is also because the belief in medicinal or mystical properties of it. People eat shark fin soup not only for the status and rarity but also the (unproven) properties like anti aging, combating disease, restorative and regeneration, etc. If anything is to blame, ultimately it’d be how we center humanity as the leading point in our imaginative reality/socio-construct rather than how it is in actuality. This is why diamond which consist of one of the most abundant element in the universe (that we could even create in a lab) is much more expensive than gold simply because of supply, demand and some manipulation
Interesting. I'm now 71, and well over 50 years ago, when I was in my early teens, my father told me that the eels all migrate to the Sargasso Sea, and that's where the larvae are found. So I guess the new breakthrough is that we have found mature adult eels at the end of the migration, actually entering the Sargasso Sea.
It's that they had never been observed mating for one thing ,, from a radio program a few days ago coincidentally , otherwise I know nothing about eels much until this video.
yea this is mostly all clickbait and old news. It's not like it was all a mystery. But this guy makes it sound like we knew nothing until this recent "study". That's completely wrong.
Hello ! May Allah protect and guide you to his light and happiness in this life and the hereafter, God bless, Ameen. Excuse me for giving a little presentation of Islam, because it is very misunderstood nowadays, especially on those « Antichrist's » times, where media and politics are mixed to distort history and truth. Thank you very much for your time. Islam is an arabic word that means the Surrender to the One and Only God, our Creator, Protector, Provider, who gives us life and all that we have, we are safe and sound by his will and grace, we are His and to Him we return, and we have to thank him in this trial life by submitting to him by our free will, or later in the Day of judgment when it's too late to save our own skin. Islam was the original Religion descended to earth from heaven with Adam and Eve (peace and blessing be upon them) in the beginning of humanity. and was passed to people with the succession of the 124 000 prophets and 315 messengers of God to all nations and civilizations since, passing by Noah, Abraham, Isaac, Jacob, Ismaël, Joseph, Moses, Aaron, Joshua, David, Solomon and Jesus (Peace and blessing be upon them) during the history of mankind, the last replaces and completes the previous, until the succession of the last messenger of God fourteen centuries ago, Muhammad (Peace and blessing be upon him) to complete the noble morals of all mankind, to bring humans and jinns out of darkness into light, and to purify people's religion and belief from corruption and polytheism, and return it to purity and true monotheism, like it was in the times of the prophets (Peace and blessing be upon them). Many Religions that we know nowadays, at their beginning were true and under Islam, initiated by one of the prophets of God, but their original teachings, history and scriptures have been corrupted over time with falsification and polytheism, or lost and replaced with false ones. That's why Islam is the only Religion accepted by God nowadays, which consists in bearing witness that there is no god besides Allah (God in Aramaic, the original language of Jesus and the Gospel), and that Muhammad is His servant and messenger, just like Jesus and Moses and others are His servants and messengers. Never a messenger of God said he was God or literally son of God, it was the people after him who changed the words of God and corrupted the Religion. God is unique and absolute, He does not need to have a family and sons or to associate anyone else with His kingdom, He can simply create whatever He wants, everything belongs to Him, and to Him everything will return. Allah said in Surah Al-Mu’minun : “God has never begotten a son, nor is there any god besides Him. Otherwise, each god would have taken away what it has created, and some of them would have gained supremacy over others. Glory be to God, far beyond what they describe. The Knower of the hidden and the manifest. He is exalted, far above what they associate. (91-92 / Translated by ITANI). Allah means the one and only God, the God of all prophets and creatures, the creator of the universe and mankind, and the Master of the Day of judgment, where our destiny, Hell or Paradise, is decided based on our faith and deeds in this trial life, and above all, Allah's mercy. Allah said in Surah Al-Ikhlas : In the name of God, the Gracious, the Merciful. Say, “He is God, the One. God, the Absolute. He begets not, nor was He begotten. And there is none comparable to Him.” (1-4 / Translated by ITANI). Allah said in Surah An-Nisa : O FOLLOWERS of the Gospel! Do not overstep the bounds [of truth] in your religious beliefs, and do not say of God anything but the truth. The Christ Jesus, son of Mary, was but God's Apostle - [the fulfilment of] His promise which He had conveyed unto Mary - and a soul created by Him. Believe, then, in God and His apostles, and do not say, "[God is] a trinity". Desist [from this assertion] for your own good. God is but One God; utterly remote is He, in His glory, from having a son: unto Him belongs all that is in the heavens and all that is on earth; and none is as worthy of trust as God. Never did the Christ feel too proud to be God's servant, nor do the angels who are near unto Him. And those who feel too proud to serve Him and glory in their arrogance [should know that on Judgment Day] He will gather them all unto Himself: (171-172 / Translated by Muhammad Asad). Allah the Most Merciful said in Surah Ali-Imran : Behold, the only [true] religion in the sight of God is [man's] self-surrender unto Him; and those who were vouchsafed revelation aforetime took, out of mutual jealousy, to divergent views [on this point] only after knowledge [thereof] had come unto them. But as for him who denies the truth of God's messages - behold, God is swift in reckoning! Thus, [O Prophet,] if they argue with thee, say, "I have surrendered my whole being unto God, and [so have] all who follow me!" - and ask those who have been vouchsafed revelation aforetime, as well as all unlettered people, "Have you [too] surrendered yourselves unto Him?" And if they surrender themselves unto Him, they are on the right path; but if they turn away - behold, thy duty is no more than to deliver the message: for God sees all that is in [the hearts of] His creatures. Verily, as for those who deny the truth of God's messages, and slay the prophets against all right, and slay people who enjoin equity - announce unto them a grievous chastisement. It is they whose works shall come to nought both in this world and in the life to come; and they shall have none to succour them. (19-22 / Translated by Muhammad Asad).. God said : Say, “We believe in Allah, and in what was revealed to us, and in what was revealed to Abraham, and Ishmael, and Isaac, and Jacob, and the Patriarchs, and in what was given to Moses and Jesus, and in what was given to the prophets from their Lord. We do not differentiate between any of them. And to Him, we surrender.” (2:136 / Translated by Community) Salam (Peace)
The race to find the youngest eel in nature is like the race to be the first commenter on RUclips. It's been around for ages and they look really different from an average specimen.

The oldest European eel was supposedly 150 + years old (the Brantevik eel). They were kept in wells to keep the water clean and has since been found in many old wells, still alive.
@@twinturboray about the Branteviks eel, it's true the exact age couldn't be proven because they couldn't find the ear-bone. In another case of well eel ( Urshult eel), the age however could be proven to be minimum 88+ yo. The fact, that eels in centuries have been kept in wells as natural filters is indisputable though.
@@lise1255 A very famous book, Swedish. Author: Fritjof Nilsson Piraten. It's also a famous serie for TV. The now EXTREMELY famous actor Stellan Skarsgård, played the 14 year old Bombi Bitt. The Eel has a certain part in the book...
This type of Eel has been around a good while (before the breakup and separation from Europe). Their breeding grounds seemingly have never changed regardless of continental drift. Chances are you're correct on it being the location being where they first evolved, and as the land mass separated they just started wandering & adapting to other environments over time.
The continents drift apart and the Sargasso Sea is probably the oldest soil of the Atlantic ocean, existed when the entire ocean was just a lake... And now somehow they are the victim of their own habit of depending on their lifecycle of going to exactly one 'orgy' away from the shore where predators might too easily find them... to mate and reproduce and then go nicely to shore... the idea of having one big 'orgy' is also a clever survival trick, you make so many critters at once that the available predators just can't eat them all and enough of them do survive...
Eels are remarkable. It's when juveniles swim back thousands of km and then will even climb up waterfalls and dams to get to the habitats they are adapted to spending the majority of their lives in that you know... These fish super evolved.
Glass eels fishing has been cancelled this year in Atlantic Canada, but there are hundreds of poachers who have decided not to pay attention. I live on a tidal river, and my backyard is the first stream that enters the river and it is a breeding area for the eels. They are now endangered in my area.

I also grew up in the Annapolis valley and I can remember people harvesting glass eels from the tidal boar rivers feeding the Digby gut / Annapolis basin !!
Over my lifetime, I've read again and again about the mystery of eel migration and reproduction. It's been a real obsession for some folks. But the most important lesson I feel from this video is this: these guys are really cute! In each stage of life, too. Another critter that looks like it's serenely smiling. I know it's not, but I don't care! They aren't harmed by my anthropomorphizing.

Looking back in my fishing diaries eels were fairly common in freshwater and near the coast until 1993. In the last 30 years I have only caught (and returned) three small ones. Eels now have protected status by the Environment Agency as they are endangered. Adult eels ae pretty tough cookies and can tolerate poor conditions better than most fish. At one time eels were the only fish able to survive in the river Thames. So it can't simply be pollution of our freshwaters that is leading to their demise. I suspect there is something nasty afoot in the Sargasso Sea.
@@HappyBeezerStudios Eels used to be a delicacy. Cut the head off, remove the guts, remove the skin (like taking off a stocking), chop into sections and simmer in water for 20 minutes and they come out jellied. They also should have stopped moving by then.
Have you considered donating your fishing logs to a university one day? I think it could be a valuable treasure trove of information about biodiversity through the decades!
Hello ! May Allah protect and guide you to his light and happiness in this life and the hereafter, God bless, Ameen. Excuse me for giving a little presentation of Islam, because it is very misunderstood nowadays, especially on those « Antichrist's » times, where media and politics are mixed to distort history and truth. Thank you very much for your time. Islam is an arabic word that means the Surrender to the One and Only God, our Creator, Protector, Provider, who gives us life and all that we have, we are safe and sound by his will and grace, we are His and to Him we return, and we have to thank him in this trial life by submitting to him by our free will, or later in the Day of judgment when it's too late to save our own skin. Islam was the original Religion descended to earth from heaven with Adam and Eve (peace and blessing be upon them) in the beginning of humanity. and was passed to people with the succession of the 124 000 prophets and 315 messengers of God to all nations and civilizations since, passing by Noah, Abraham, Isaac, Jacob, Ismaël, Joseph, Moses, Aaron, Joshua, David, Solomon and Jesus (Peace and blessing be upon them) during the history of mankind, the last replaces and completes the previous, until the succession of the last messenger of God fourteen centuries ago, Muhammad (Peace and blessing be upon him) to complete the noble morals of all mankind, to bring humans and jinns out of darkness into light, and to purify people's religion and belief from corruption and polytheism, and return it to purity and true monotheism, like it was in the times of the prophets (Peace and blessing be upon them). Many Religions that we know nowadays, at their beginning were true and under Islam, initiated by one of the prophets of God, but their original teachings, history and scriptures have been corrupted over time with falsification and polytheism, or lost and replaced with false ones. That's why Islam is the only Religion accepted by God nowadays, which consists in bearing witness that there is no god besides Allah (God in Aramaic, the original language of Jesus and the Gospel), and that Muhammad is His servant and messenger, just like Jesus and Moses and others are His servants and messengers. Never a messenger of God said he was God or literally son of God, it was the people after him who changed the words of God and corrupted the Religion. God is unique and absolute, He does not need to have a family and sons or to associate anyone else with His kingdom, He can simply create whatever He wants, everything belongs to Him, and to Him everything will return. Allah said in Surah Al-Mu’minun : “God has never begotten a son, nor is there any god besides Him. Otherwise, each god would have taken away what it has created, and some of them would have gained supremacy over others. Glory be to God, far beyond what they describe. The Knower of the hidden and the manifest. He is exalted, far above what they associate. (91-92 / Translated by ITANI). Allah means the one and only God, the God of all prophets and creatures, the creator of the universe and mankind, and the Master of the Day of judgment, where our destiny, Hell or Paradise, is decided based on our faith and deeds in this trial life, and above all, Allah's mercy. Allah said in Surah Al-Ikhlas : In the name of God, the Gracious, the Merciful. Say, “He is God, the One. God, the Absolute. He begets not, nor was He begotten. And there is none comparable to Him.” (1-4 / Translated by ITANI). Allah said in Surah An-Nisa : O FOLLOWERS of the Gospel! Do not overstep the bounds [of truth] in your religious beliefs, and do not say of God anything but the truth. The Christ Jesus, son of Mary, was but God's Apostle - [the fulfilment of] His promise which He had conveyed unto Mary - and a soul created by Him. Believe, then, in God and His apostles, and do not say, "[God is] a trinity". Desist [from this assertion] for your own good. God is but One God; utterly remote is He, in His glory, from having a son: unto Him belongs all that is in the heavens and all that is on earth; and none is as worthy of trust as God. Never did the Christ feel too proud to be God's servant, nor do the angels who are near unto Him. And those who feel too proud to serve Him and glory in their arrogance [should know that on Judgment Day] He will gather them all unto Himself: (171-172 / Translated by Muhammad Asad). Allah the Most Merciful said in Surah Ali-Imran : Behold, the only [true] religion in the sight of God is [man's] self-surrender unto Him; and those who were vouchsafed revelation aforetime took, out of mutual jealousy, to divergent views [on this point] only after knowledge [thereof] had come unto them. But as for him who denies the truth of God's messages - behold, God is swift in reckoning! Thus, [O Prophet,] if they argue with thee, say, "I have surrendered my whole being unto God, and [so have] all who follow me!" - and ask those who have been vouchsafed revelation aforetime, as well as all unlettered people, "Have you [too] surrendered yourselves unto Him?" And if they surrender themselves unto Him, they are on the right path; but if they turn away - behold, thy duty is no more than to deliver the message: for God sees all that is in [the hearts of] His creatures. Verily, as for those who deny the truth of God's messages, and slay the prophets against all right, and slay people who enjoin equity - announce unto them a grievous chastisement. It is they whose works shall come to nought both in this world and in the life to come; and they shall have none to succour them. (19-22 / Translated by Muhammad Asad).. God said : Say, “We believe in Allah, and in what was revealed to us, and in what was revealed to Abraham, and Ishmael, and Isaac, and Jacob, and the Patriarchs, and in what was given to Moses and Jesus, and in what was given to the prophets from their Lord.

It's probably habitat fragmentation. Freshwater disconnected from other freshwater. Dried wetlands. Straightened rivers. Disturbance by ships and ferries. As well as climate change.
The history of how eels make baby eels, is like the entire history of science!! Progressions form "eels come from dead eels or pieces of eel skin - or maybe sunlight reflecting off the Nile..." to more and more precise data/information, and the use of sophisticated tools and instruments to gather solid imperical data which helps eventually lead to TRUTH, lol. Bravo, science!!
As long as it's not fallaciously used by governments and corporations to say, shut the world down based on lies about a virus that are now thoroughly debunked, many by testimony in front of the US Congress.
Hey, what about our eels in the Southern Hemisphere? They travel far inland and even cross damp fields then return to the Pacific Ocean to reproduce. Amazing creatures.
I wonder how they developed such a complex behavior. Were they alive 130+ million years ago, when Europe and North America were still close together? That would mean they’ve been swimming further and further to reach their spawning grounds as the continents have separated, but I can’t think of any other explanation as to why a 1.5 year migration through a habitat far more dangerous than their freshwater home would evolve in such a species, unless the Sargasso Sea is the holy grail of baby eel sanctuaries.
New Zealand has a native eel which also spawns in the ocean, but it is still not known for certain exactly where in the Pacific that is. I have seen "Near Tonga" and "Near New Caledonia" mentioned.
I've been waiting for a water creature to start my subscription to the pin club, and it's one of my favorites! Glass eel fishing is a big part of the economy where I grew up, hearing that it's often illegal or trafficked is...well...interesting, but honestly not surprising to me 😅 those babies can sell for thousands per pound, one fishing trip and you're rolling in the millions no joke 👀 for poor rural fishing towns that kind of money is no joke
Quite similar to the New Zealand longfin eel, which is a very long-lived fish, with records of females reaching 106 years old and weighing up to 24 kg. They migrate to the Pacific Ocean near Tonga to breed at the end of their lives.
During the International Geophysical Year (1956) researchers trawling in the Sargasso brought up a larval eel that was five inches long. As the usual eel larva is only 1/10th of an inch long, they calculated that if this larval form had grown to adulthood proportionally, the adult would have been 200 feet long. This would explain old sailors' tales about sea serpents in the Sargasso.
On the other hand Japanese eels do have gonads and are also bred by authorities and farmers in the northern parts of the Philippines. They were originally brought there during World War Two when the Japanese occupied the Philippines. The area in the Cordilleras where they are farmed is famous for its rice terraces, and the farmers grow eels as well as rice in the same terraces. Apparently the eels are also beneficial to the rice plants, eating some insects that can damage the plants, and they provide extra income for the rice farmers.
I don't think that's correct, it seems all eel farms start with wild caught glass eels, i have not seen any credible claim of captive breeding, and i imagine rearing the oceanic planktonic larva is going to be a challenge even if were possible to get the adults to spawning physiology in a captive environment.
@@Appletank8 There are what is sometimes called "W" and "Z" where both are required, but do not determine the internal gender of the offspring; gender is influenced by external factors such as: temperature during incubation; nutrient availability during larval/juvenile stage; local gender ratios during adolescent/adult stage. Some species do not deviate to a specific gender until just before becoming mature and participating during mating season(s); though most that follow such strategy often die just after mating/incubating eggs.
The glass eels have another name, they’re called elvers which I think is amazing. The Australian and surrounding countries eels are also just as strange and nobody is sure where or how they reproduce just that it’s somewhere near New Caledonia. I love finding them in the wild when I’m out filming for my documentaries, they can be so far up rivers that have multiple waterfalls and seemingly impassable terrain but somehow still get there
"The glass eels have another name, they’re called elvers" Did you even watch the video? It clearly shows that 'elvers' are the stage AFTER 'glass eels'. 1:15 🤦♂ So, if anybody is calling glass eels 'elvers', then they don't have a clue what their talking about, apparently just like you don't.
I live in Europe and I’ve seen lots of eels when I was a child. My dad used to take me out fishing very early in the morning when the grass was still dewy. He used to fish in two ponds that were quite close together but separated by a grassland. In the early hours of the morning we could see the eels slider from one pond to the other. They do so to look for other feeding grounds. It’s quite a sight. Now sadly eels are an endangered species. It’s true that the glass eels are traded. Especially Chinese people think it’s a delicatesse.
We have known about this since the late 70s when it was filmed of eels spawning on Sargasso weed rafts, it was later they found out that Eels will use the natural ocean currents, Like they will arrive in Europe using the Gulf Stream, and they will use the North Atlantic Drift current to latch onto the Southern Gulf Drift current which takes them into the starting point of the Weed Rafts of the Florida Coast where they end up in the Sargasso Sea to spawn
I was taught that eels from Britain went to the Sargasso to breed in biology class at school in 1970-71. I'm a little surprised to be told this has only just been discovered.
Many years ago I worked with a captain who had sailed around most of the worlds oceans on Supertankers. He told us that a lot of eels are born or hatched in the Sargasso Sea, as he had talked to fishermen in that area who sometimes caught elvers (baby eel). Maybe it was just a "fisher-mans" story, but who knows.
There's this theory about eels going to the bermuda triangle (sargasso sea) to sacrifice themselves to the alien eel god (or satan perhaps) to create more eels. I liked that wacky theory since eels (especially morays) looks like it came out of lovecraftian horror.
Fascinating video about fascinating animals! A relative of mine is convinced that eels are endadgered due to US military equipment in the sargasso sea messing with the animals navigation system, as eels only recently got endangered, and they can only breed in one place. I'm not so sure myself, but it'd be cool to understand why they need to go to the sargasso sea, and how they find their way there.
Eels: Unbothered. Moisturized, Happy. In my lane. Focused. Flourishing. Humans: okay but why Eels: Slightly bothered. Still moisturized. Probably happy? In a lane. Slightly distracted from this collar. Potentially flourishing.
Who else thought from the title that this was going to be a story about how we didn't know who the ancient dinosaur-era ancestors of the eels were, and instead found an even weirder story about how we didn't know where eels got their gonads?
American eels also spawn in the Saragaso sea. I remember when I was a kid all you had to do was throw your hook in a river and reel it in. You were almost guaranteed to have an eel on the line
All I can think of the Eel Song from Mighty Boosh... Eels up inside ya Findin an entrance where they can Eels up inside ya Findin an entrance where they can
Surely someone has kept eels in captivity to see their full life cycle, right? Why would that not have worked out? They just never reach the last stage if they don't make the journey to the Sargasso Sea?
I have stopped eating eel despite liking it. Due to complex reproduction and life cycles, they can't really be farmed so they are actually just catching the wild baby eels and then growing them, but this is destroying their wild populations and the overall population is shrinking.
But the thing of them being born in the Sargazzo sea and spending their adult life in Europe was already known at least when I was a kid in the 80s. It's interesting that they do the opposite of what the atlantic salmon does: living in the sea and migrating to the rivers to reproduce and die.
Here's a thought: could someone use e-dna (environmental dna) to try and narrow down the specific spawning site? I know currents would make it complicated, but it'd be less expensive than disposable GPS tags
It takes over a third to a half of a current human lifespan just to see them grow gonads!?! How have they not gone extinct yet!?! We eat so many of them!! Do they have a ton of eggs and most of them don't die die to predators and things!?! I have so many more questions that need answered now!!!
the IUCN lists them as critically endangered, which is one step away from extinction. apparently eels are in particularly desperate need of bans on catching or selling them, but the fishery lobby is successfully delaying regulatory action, and it's sort of generally failing to register that a fish that used to be so common and cheap is now in need of protection.
Oh my... I had no idea since they are sold everywhere for cheap... I really hope they get the help they need then soon so we can have our slippery slimy friends for a long time to come🥺😥💜 I really hate how governments can be essentially bought out since people work in governments, sometimes I think we'd be better off with literal monkeys in charge...
Well, we have lost ~98% of the European eel population in the last 35 years. Majority of the glass eels are caught to be raised and slaughtered in eel farms. And the general population has no idea because those farms market themselves as if they were breeding them. But yes, they spawn a lot of offspring at once. It's why they lose the digestive tract during migration, to make room for as many egg/sperm cells as possible.
This works only for north Atlantic eels. What about South Atlantic. North Pacific. South Pacific. Indian Ocean. There are eels everywhere. There was a Xena show where they were handling (in New Zealand) these brutes of eels, had to be 5 feet long and as big as your thigh. They're not all going to the Sargasso Sea.
I wonder if anyone will make a comment about the quest to find eel male reproductive organs by Sigmund Freud, alluring to the portrail of this event by a famous youtube channel Sam'o'nella
This is actually really big news I have so many books on fish that just have no idea about the full cycle of eels. We used to help the Elvers on their journey when we were kids lol they crawl across land trying to get to other water.
Ohh man, you think it's silly but it's a Multi million dollar operation, look at m6 home province, it just closed the glass eel fisheries, an people still pocthing them, 1:50
@@Omni_Shambles ahah yes you got that right, the only thing we don't know is , do they live birth or do they lay eggs like other serpent like critters?
Could you please create an archive showing the different variations of prior pins? I'm having trouble identifying the rarity of mine, since only the current animal is shown on the chart in the DFTBA store. Thanks for considering the suggestion :)
The town I live in (in the UK) has a major eel river running past the end of the local jetty and I have caught specimens up to and over four pounds though most of them are smaller as they start their journey from sea to river. One major highlight is the rare occasion when we can look down into the water and see literally millions of juveniles swimming at the surface around the end of the jetty.
It's been known now for over 25 years that the Northern Atlantic Common Eel, spawn in Sargasso Doldrums, it also happens in the South Atlantic and also there are same sorts of Doldrums in the Pacific for more Eels to spawn in It was filmed in the Sargasso Sea eels spawning on the Sargasso weed beds which comes from Mexico Gulf

I feel like a few years back we discovered an insect that we thought was two different species ending up being a life cycle stage. So interesting we finally connected the dots with eels too
A Devonshire farmer told me couple of years back that eels don't die until after 12 o' clock on the day they're caught. Even if you cut them up and put them in the fridge they quiver and twitch until seconds into the new day. They wait until a storm and then cross from one field to the next by thunder and lightning. On Christmas Eve when the other animals kneel down at midnight to herald the birth of Our Saviour eels and ravens congregate in the graveyard.
Eels descended from the Goa'uld. Everything Stargate fan knows this through and through!!! The first fish I ever caught was an eel in the St. John's River, Florida, around 4 years old.
The north american freshwater eel is also a mystery. They are born way upstream in very shallow creeks and travel downstream all their lives. No one knows how the eggs get upstream in the first place. The adults never go back.
Continental drift was a main factor in eel evolution. It is believed the common ancestor of eels lived east of the supercontinent Pangaea, in the Tethys Ocean (present day Indonesia). The ancestral eel, like modern eels, must have made regular migrations between its spawning region in the ocean and its nursery areas in the rivers. As the northern part of Pangaea separated from the southern part, the Tethys Ocean was connected with the sea in the east with the sea in the west. The ancestral eel was thus able to spread into the western sea.
I remember being in college around 2015 and hearing my ichthyology (fish science) professor say with a straight face that we don't know where eels breed. "Somewhere in the Atlantic" was as close as we had narrowed it down. Still blows my mind.
I think that I, on a Danish Cemetery, saw a sign that this person had been the one to find out that the eels migrated to Sargasso to make new and small eels!

I always hear about "We only know about 10% of our oceans" but now seeing how only last year people understood how an animal life cycle works, makes this claim way more evident in my mind now.

I still have questions… 1) Do we have enough information to simulate this long migration process and reproductive end cycle in the lab? If not why? There are theories that this has to do with salinity adaption, stress, oceanic pressure adaption, and even the phases of the moon. Which are causal and which are coincidental? 2) You mentioned physiological changes in the eels late stage reproductive cycle. Do we know why they must travel to these specific locations? 3) other catadromous fish such as the Australian greyling reproduce near the mouths or rivers and estuaries instead of the depths of the ocean. Why is this? How do they differ from eels? 4) Does this reproduction process shorten their life span? In other words would they live longer if they had not gone through this stressful migration and adaption but never reproduce? Or would they actually be able to reproduce? Would not making it the full mean they are fertile but have no other eels to mate with given the variability of their location to the spawning area. Thus making their reproduction meaningless.
I found a glass eel in a river as a kid while hunting minnows it was nearly invisible, i also found a pink eel in a rock pool when i was around 8 it was the lenth of my arm and as thick as my wrist.
I just want to thank the countless men and women who work most of their lives to uncovering the secrets of how eels do it. Science is so very important, especially in the world where people lie about what they eat in the morning.

I did a project on european eels when I was at uni, back in 2017. Eel migration was still a bit of a mystery then, we literally had an eel expert in to answer questions and most of his answers were "we don't know yet". Cool to hear that 5-6 years later, a little more of the mystery has been solved!
It is nice to have some mysteries and fun when those mysteries can get resolved.
We've known the general "the come from near the Sargasso" for around a century though. Some European scientist got a bunch of ship captains to periodically let down nets, and send him the catch and the location so he could do a survey of what was going through which sections of the Atlantic. The conclusion (after sifting through several years of results) was the determination that their spawning grounds are in the Sargasso. They were recently caught _on film,_ but that's about it.
We've known where European Eels come from for around a century.
We still don't know. We have never seen the mate
@@thanhavictus and the egg
@@thanhavictus Leave them some privacy, you pervert.
nevermind the larval stage - adult eels go from living 25+ years in freshwater, migrating kilometers over land when it rains (you forgot to mention that part) to all sorts of ponds and lakes not even connected to the ocean to migrating back through the ocean at depths of up to 1400m?! goddamn that's a crazy fish!
also that ~25 year age minimum for breeding, and spawning just one time before dying, explains my confusion about hearing that european eels are nowadays considered to be a highly threatened species [edit: IUCN critically endangered, the closest category to extinction] after previously being one of the most common and cheap fish everybody took for granted. 😬 I think we have a passenger fish situation on our hands. though in terms of reproduction, it's more like whaling or fishing greenland sharks.
Technically CR (Critically Endangered) is the second closest category to Extinct, not the closest. Extinct in the Wild is the category between CR and E.
I work with CR species in the wild and have had to write up some of the IUCN species descriptions.
@@earthknight60 there is no distinction between extinction in the wild and full extinction for the european eel since it can't be bred in captivity.

According to naturalist Gerald Durrell, elvers (the stage of young eel that migrates from the ocean back to inland waters) don't just migrate over land when it rains -- he tells of seeing columns of the little critters writhing their way over the dusty ground on the Greek island of Corfu on a dry sunny day when he was a boy.

Hi! Marine biologist/zoologist here. We have seen eels travel to the Sargasso Sea en masse once a year and then baby eels swim back to the freshwater systems they grow up in. But because science is science, it can't be stated as mystery solved until the spawning behavior is witnessed in real time.
Science isn't a collection of unassailable facts. It's a method. Some things can be safely extrapolated, some cannot. Science has discovered a great deal about and solved quite a few mysteries about say, black holes, without directly observing specific phenomenon. The effect the phenomenon had combined with other direct observations led to a discovery with no direct observations. If black holes interest you I'd suggest looking them up, there's too much to go into here. My point is, you're sort of correct, but not empirically.
Hi marine biologist/ zoologist, I'm somebody also interested in the field and just recently did an internship at an aquarium here in Finland, which, coincidentally, happens to be the only place in the world where a yellow eel has turned into a silver eel naturally, or well, spontaneously. I managed to watch as scientist from the Netherlands weighed, drew blood, did ultrasounds and measured some of the eels at the aquarium. So maybe, in the future, they might spot the signs of an eel turning silver! And then impregnate that eel with sperm from male eels from the research lab for eels in the Netherlands. So we might see the whole process soon! Hopefully, of course!
Then science can't say that it's still a mystery lol
(Yes the eel mamas were quite big haha, the scientists let me handle one of the specimens, very cool experience. Would recommend eel touching at least once in your marine biologist life!)
Whatever dude...no one cares whether you are a marine or arse or whatever biologist...they are tasty...thats all that matters to me.
@@_klc_ When a marine biologist / zoologist says, it's a must to touch a eel, it's ok but when I tell woman it's fun to touch my yellow eel, they call it seksual harassment. ☹
@@sbtig9637 I know I'm not OP, but just wanted to reply to this! They are tasty, they are indeed, but at least here in the Baltic sea the population is dying. If we don't research how they reproduce, the eels we know and love (even by their taste, yes) will be gone
There's a phenomenal book by Patrik Svensson called "Ålevangeliet" ("The Eel Gospels") that studies the murky and enigmatic nature and history of eels. It tells the tale of the Sargasso migration told about in this video, but also chronicles mankind's attempt to locate their genitalia (Sigmund Freud studied eels for years in his youth; the book strongly hints that his later frustrations derive from his failure to locate eel genitalia), and how eels that are stuck in earlier states of being (such as as yellow eels) kind of seem to not age, like at all, over literal decades. The book has also been turned into an opera.
Now THAT is a weird flex 🤔
Okay. I love how frustrated he got over eel genitals, but the fact it is an opera makes me want to go to the opera for the first time in my life.
The more and more you look into eels, the weirder and weirder every story gets.
Was this opera written by Skippy The Magnificent?
@@oakenshadow6763 no. No. No no no.
Nothing will ever get me to opera.
Well. Maybe stripper opera.
Maybe.
I will never understand why things that have no flavor become "delicacies". Shark fin is like this too, and even worse. Fishers catch them, hack the fins off, and leave them to die. It devastates shark populations. Shark fin is flavorless and the texture is weird, and yet it's still considered a delicacy and a status symbol.
Because humans are gullible.
Slap the word delicacy onto anything and it becomes "special" and exclusively for the wealthy. Then classist fools fall for the specialness of the delicacy and pay ridiculous amounts of money for it without using their brains. We may be great apes, but so much of our behavior is still "monkey see, monkey do."
Cause they are rare or expensive ig.
Kinda like how lobsters or black caviar were the poor person's food in the past due to being abundant, but got fished so much that now they are a delicacy ig.
Able to spend money on expensive, pointless things. Is part of showing off their wealth. Most people will be respectful and not tell the emperor he is not wearing clothes.
@@NexuJin That's not being respectful, that's participating in delusion based on fear and threat of repercussion.
I feel like part of it is also because the belief in medicinal or mystical properties of it. People eat shark fin soup not only for the status and rarity but also the (unproven) properties like anti aging, combating disease, restorative and regeneration, etc.
If anything is to blame, ultimately it’d be how we center humanity as the leading point in our imaginative reality/socio-construct rather than how it is in actuality. This is why diamond which consist of one of the most abundant element in the universe (that we could even create in a lab) is much more expensive than gold simply because of supply, demand and some manipulation
The real mystery is... Who looked at those things and thought: 'Pie. This belongs in a pie."
the people who put all animals in pies.
Truely, not their finest moment
Hungry people.
English food is so ...omitted... that something/anything had to be better than what they last ate. 😜
you know they recreated mammoth meat by biotechnology just to know how mammoth tasted...
Humans are no different from a slime mold by nature.
Interesting. I'm now 71, and well over 50 years ago, when I was in my early teens, my father told me that the eels all migrate to the Sargasso Sea, and that's where the larvae are found. So I guess the new breakthrough is that we have found mature adult eels at the end of the migration, actually entering the Sargasso Sea.
It's that they had never been observed mating for one thing ,, from a radio program a few days ago coincidentally , otherwise I know nothing about eels much until this video.
yea this is mostly all clickbait and old news. It's not like it was all a mystery. But this guy makes it sound like we knew nothing until this recent "study". That's completely wrong.
@@philip5940 We still haven't observed them mating. And I wouldn't want to.
Hello ! May Allah protect and guide you to his light and happiness in this life and the hereafter, God bless, Ameen. Excuse me for giving a little presentation of Islam, because it is very misunderstood nowadays, especially on those « Antichrist's » times, where media and politics are mixed to distort history and truth. Thank you very much for your time.
Islam is an arabic word that means the Surrender to the One and Only God, our Creator, Protector, Provider, who gives us life and all that we have, we are safe and sound by his will and grace, we are His and to Him we return, and we have to thank him in this trial life by submitting to him by our free will, or later in the Day of judgment when it's too late to save our own skin. Islam was the original Religion descended to earth from heaven with Adam and Eve (peace and blessing be upon them) in the beginning of humanity. and was passed to people with the succession of the 124 000 prophets and 315 messengers of God to all nations and civilizations since, passing by Noah, Abraham, Isaac, Jacob, Ismaël, Joseph, Moses, Aaron, Joshua, David, Solomon and Jesus (Peace and blessing be upon them) during the history of mankind, the last replaces and completes the previous, until the succession of the last messenger of God fourteen centuries ago, Muhammad (Peace and blessing be upon him) to complete the noble morals of all mankind, to bring humans and jinns out of darkness into light, and to purify people's religion and belief from corruption and polytheism, and return it to purity and true monotheism, like it was in the times of the prophets (Peace and blessing be upon them).
Many Religions that we know nowadays, at their beginning were true and under Islam, initiated by one of the prophets of God, but their original teachings, history and scriptures have been corrupted over time with falsification and polytheism, or lost and replaced with false ones. That's why Islam is the only Religion accepted by God nowadays, which consists in bearing witness that there is no god besides Allah (God in Aramaic, the original language of Jesus and the Gospel), and that Muhammad is His servant and messenger, just like Jesus and Moses and others are His servants and messengers. Never a messenger of God said he was God or literally son of God, it was the people after him who changed the words of God and corrupted the Religion. God is unique and absolute, He does not need to have a family and sons or to associate anyone else with His kingdom, He can simply create whatever He wants, everything belongs to Him, and to Him everything will return. Allah said in Surah Al-Mu’minun : “God has never begotten a son, nor is there any god besides Him. Otherwise, each god would have taken away what it has created, and some of them would have gained supremacy over others. Glory be to God, far beyond what they describe. The Knower of the hidden and the manifest. He is exalted, far above what they associate. (91-92 / Translated by ITANI).
Allah means the one and only God, the God of all prophets and creatures, the creator of the universe and mankind, and the Master of the Day of judgment, where our destiny, Hell or Paradise, is decided based on our faith and deeds in this trial life, and above all, Allah's mercy.
Allah said in Surah Al-Ikhlas : In the name of God, the Gracious, the Merciful.
Say, “He is God, the One. God, the Absolute. He begets not, nor was He begotten. And there is none comparable to Him.” (1-4 / Translated by ITANI).
Allah said in Surah An-Nisa : O FOLLOWERS of the Gospel! Do not overstep the bounds [of truth] in your religious beliefs, and do not say of God anything but the truth. The Christ Jesus, son of Mary, was but God's Apostle - [the fulfilment of] His promise which He had conveyed unto Mary - and a soul created by Him. Believe, then, in God and His apostles, and do not say, "[God is] a trinity". Desist [from this assertion] for your own good. God is but One God; utterly remote is He, in His glory, from having a son: unto Him belongs all that is in the heavens and all that is on earth; and none is as worthy of trust as God. Never did the Christ feel too proud to be God's servant, nor do the angels who are near unto Him. And those who feel too proud to serve Him and glory in their arrogance [should know that on Judgment Day] He will gather them all unto Himself: (171-172 / Translated by Muhammad Asad).
Allah the Most Merciful said in Surah Ali-Imran : Behold, the only [true] religion in the sight of God is [man's] self-surrender unto Him; and those who were vouchsafed revelation aforetime took, out of mutual jealousy, to divergent views [on this point] only after knowledge [thereof] had come unto them. But as for him who denies the truth of God's messages - behold, God is swift in reckoning!
Thus, [O Prophet,] if they argue with thee, say, "I have surrendered my whole being unto God, and [so have] all who follow me!" - and ask those who have been vouchsafed revelation aforetime, as well as all unlettered people, "Have you [too] surrendered yourselves unto Him?" And if they surrender themselves unto Him, they are on the right path; but if they turn away - behold, thy duty is no more than to deliver the message: for God sees all that is in [the hearts of] His creatures.
Verily, as for those who deny the truth of God's messages, and slay the prophets against all right, and slay people who enjoin equity - announce unto them a grievous chastisement.
It is they whose works shall come to nought both in this world and in the life to come; and they shall have none to succour them.
(19-22 / Translated by Muhammad Asad)..
God said : Say, “We believe in Allah, and in what was revealed to us, and in what was revealed to Abraham, and Ishmael, and Isaac, and Jacob, and the Patriarchs, and in what was given to Moses and Jesus, and in what was given to the prophets from their Lord.

About to make the same exact comment. Nothing new in this vid. Clickbait.
The race to find the youngest eel in nature is like the race to be the first commenter on RUclips. It's been around for ages and they look really different from an average specimen.

The oldest European eel was supposedly 150 + years old (the Brantevik eel). They were kept in wells to keep the water clean and has since been found in many old wells, still alive.
@@twinturboray about the Branteviks eel, it's true the exact age couldn't be proven because they couldn't find the ear-bone. In another case of well eel ( Urshult eel), the age however could be proven to be minimum 88+ yo.
The fact, that eels in centuries have been kept in wells as natural filters is indisputable though.
@@twinturboray strange to be called "kid" as 80yo.
Are we sure twinturbo didn't have a eel crawl up his butt?
Bombi Bitt!!!🇸🇪🇸🇪🇸🇪🦩
@@lise1255 A very famous book, Swedish. Author: Fritjof Nilsson Piraten. It's also a famous serie for TV. The now EXTREMELY famous actor Stellan Skarsgård, played the 14 year old Bombi Bitt. The Eel has a certain part in the book...
Now the question that remains is "Why the Sargasso Sea" was it where they first evolved into their current body style?
Pretty sure eels have looked like that since before the Sargasso Sea existed, but I don't know that for certain
This type of Eel has been around a good while (before the breakup and separation from Europe). Their breeding grounds seemingly have never changed regardless of continental drift. Chances are you're correct on it being the location being where they first evolved, and as the land mass separated they just started wandering & adapting to other environments over time.
@@Heowolf Also the dense kelp/seaweed groves probably supply a beneficial hiding ground during larval stage.
The continents drift apart and the Sargasso Sea is probably the oldest soil of the Atlantic ocean, existed when the entire ocean was just a lake...
And now somehow they are the victim of their own habit of depending on their lifecycle of going to exactly one 'orgy' away from the shore where predators might too easily find them... to mate and reproduce and then go nicely to shore... the idea of having one big 'orgy' is also a clever survival trick, you make so many critters at once that the available predators just can't eat them all and enough of them do survive...
Where do all the eels in other parts of the world come from?
Eels are remarkable. It's when juveniles swim back thousands of km and then will even climb up waterfalls and dams to get to the habitats they are adapted to spending the majority of their lives in that you know... These fish super evolved.
I wanna be an eel - only having reproductive organs when I feel like it
IN THIS DAY AND AGE YOU CAN BE A HELICOPTER IF YOU WANT.... :)

The eels don't choice it, they are made that way
Mood
Glass eels fishing has been cancelled this year in Atlantic Canada, but there are hundreds of poachers who have decided not to pay attention.
I live on a tidal river, and my backyard is the first stream that enters the river and it is a breeding area for the eels.
They are now endangered in my area.
Did you hear? We now know where eels come from. Fantastic news, isn't it?

Set up a protection zone.
I also grew up in the Annapolis valley and I can remember people harvesting glass eels from the tidal boar rivers feeding the Digby gut / Annapolis basin !!
Baby eels look like the proto animals I used to see in the old discovery shows and personally I think that's very neat
Over my lifetime, I've read again and again about the mystery of eel migration and reproduction. It's been a real obsession for some folks.
But the most important lesson I feel from this video is this: these guys are really cute! In each stage of life, too. Another critter that looks like it's serenely smiling. I know it's not, but I don't care! They aren't harmed by my anthropomorphizing.
a reel obsession, you could say
You are right. It's sometimes Ok to anthropomorphize

I've always known where eels come from. Water.
You thought poop water.
Looking back in my fishing diaries eels were fairly common in freshwater and near the coast until 1993. In the last 30 years I have only caught (and returned) three small ones. Eels now have protected status by the Environment Agency as they are endangered. Adult eels ae pretty tough cookies and can tolerate poor conditions better than most fish. At one time eels were the only fish able to survive in the river Thames. So it can't simply be pollution of our freshwaters that is leading to their demise. I suspect there is something nasty afoot in the Sargasso Sea.
people on the other side if the ocean poaching them as delicacy.
@@HappyBeezerStudios Eels used to be a delicacy. Cut the head off, remove the guts, remove the skin (like taking off a stocking), chop into sections and simmer in water for 20 minutes and they come out jellied. They also should have stopped moving by then.
Have you considered donating your fishing logs to a university one day? I think it could be a valuable treasure trove of information about biodiversity through the decades!
Hello ! May Allah protect and guide you to his light and happiness in this life and the hereafter, God bless, Ameen. Excuse me for giving a little presentation of Islam, because it is very misunderstood nowadays, especially on those « Antichrist's » times, where media and politics are mixed to distort history and truth. Thank you very much for your time.
Islam is an arabic word that means the Surrender to the One and Only God, our Creator, Protector, Provider, who gives us life and all that we have, we are safe and sound by his will and grace, we are His and to Him we return, and we have to thank him in this trial life by submitting to him by our free will, or later in the Day of judgment when it's too late to save our own skin. Islam was the original Religion descended to earth from heaven with Adam and Eve (peace and blessing be upon them) in the beginning of humanity. and was passed to people with the succession of the 124 000 prophets and 315 messengers of God to all nations and civilizations since, passing by Noah, Abraham, Isaac, Jacob, Ismaël, Joseph, Moses, Aaron, Joshua, David, Solomon and Jesus (Peace and blessing be upon them) during the history of mankind, the last replaces and completes the previous, until the succession of the last messenger of God fourteen centuries ago, Muhammad (Peace and blessing be upon him) to complete the noble morals of all mankind, to bring humans and jinns out of darkness into light, and to purify people's religion and belief from corruption and polytheism, and return it to purity and true monotheism, like it was in the times of the prophets (Peace and blessing be upon them).
Many Religions that we know nowadays, at their beginning were true and under Islam, initiated by one of the prophets of God, but their original teachings, history and scriptures have been corrupted over time with falsification and polytheism, or lost and replaced with false ones. That's why Islam is the only Religion accepted by God nowadays, which consists in bearing witness that there is no god besides Allah (God in Aramaic, the original language of Jesus and the Gospel), and that Muhammad is His servant and messenger, just like Jesus and Moses and others are His servants and messengers. Never a messenger of God said he was God or literally son of God, it was the people after him who changed the words of God and corrupted the Religion. God is unique and absolute, He does not need to have a family and sons or to associate anyone else with His kingdom, He can simply create whatever He wants, everything belongs to Him, and to Him everything will return. Allah said in Surah Al-Mu’minun : “God has never begotten a son, nor is there any god besides Him. Otherwise, each god would have taken away what it has created, and some of them would have gained supremacy over others. Glory be to God, far beyond what they describe. The Knower of the hidden and the manifest. He is exalted, far above what they associate. (91-92 / Translated by ITANI).
Allah means the one and only God, the God of all prophets and creatures, the creator of the universe and mankind, and the Master of the Day of judgment, where our destiny, Hell or Paradise, is decided based on our faith and deeds in this trial life, and above all, Allah's mercy.
Allah said in Surah Al-Ikhlas : In the name of God, the Gracious, the Merciful.
Say, “He is God, the One. God, the Absolute. He begets not, nor was He begotten. And there is none comparable to Him.” (1-4 / Translated by ITANI).
Allah said in Surah An-Nisa : O FOLLOWERS of the Gospel! Do not overstep the bounds [of truth] in your religious beliefs, and do not say of God anything but the truth. The Christ Jesus, son of Mary, was but God's Apostle - [the fulfilment of] His promise which He had conveyed unto Mary - and a soul created by Him. Believe, then, in God and His apostles, and do not say, "[God is] a trinity". Desist [from this assertion] for your own good. God is but One God; utterly remote is He, in His glory, from having a son: unto Him belongs all that is in the heavens and all that is on earth; and none is as worthy of trust as God. Never did the Christ feel too proud to be God's servant, nor do the angels who are near unto Him. And those who feel too proud to serve Him and glory in their arrogance [should know that on Judgment Day] He will gather them all unto Himself: (171-172 / Translated by Muhammad Asad).
Allah the Most Merciful said in Surah Ali-Imran : Behold, the only [true] religion in the sight of God is [man's] self-surrender unto Him; and those who were vouchsafed revelation aforetime took, out of mutual jealousy, to divergent views [on this point] only after knowledge [thereof] had come unto them. But as for him who denies the truth of God's messages - behold, God is swift in reckoning!
Thus, [O Prophet,] if they argue with thee, say, "I have surrendered my whole being unto God, and [so have] all who follow me!" - and ask those who have been vouchsafed revelation aforetime, as well as all unlettered people, "Have you [too] surrendered yourselves unto Him?" And if they surrender themselves unto Him, they are on the right path; but if they turn away - behold, thy duty is no more than to deliver the message: for God sees all that is in [the hearts of] His creatures.
Verily, as for those who deny the truth of God's messages, and slay the prophets against all right, and slay people who enjoin equity - announce unto them a grievous chastisement.
It is they whose works shall come to nought both in this world and in the life to come; and they shall have none to succour them.
(19-22 / Translated by Muhammad Asad)..
God said : Say, “We believe in Allah, and in what was revealed to us, and in what was revealed to Abraham, and Ishmael, and Isaac, and Jacob, and the Patriarchs, and in what was given to Moses and Jesus, and in what was given to the prophets from their Lord. We do not differentiate between any of them. And to Him, we surrender.”

It's probably habitat fragmentation. Freshwater disconnected from other freshwater. Dried wetlands. Straightened rivers. Disturbance by ships and ferries. As well as climate change.
The history of how eels make baby eels, is like the entire history of science!! Progressions form "eels come from dead eels or pieces of eel skin - or maybe sunlight reflecting off the Nile..." to more and more precise data/information, and the use of sophisticated tools and instruments to gather solid imperical data which helps eventually lead to TRUTH, lol. Bravo, science!!
As long as it's not fallaciously used by governments and corporations to say, shut the world down based on lies about a virus that are now thoroughly debunked, many by testimony in front of the US Congress.
Hey, what about our eels in the Southern Hemisphere? They travel far inland and even cross damp fields then return to the Pacific Ocean to reproduce. Amazing creatures.
Amazing!!!
I wonder how they developed such a complex behavior. Were they alive 130+ million years ago, when Europe and North America were still close together? That would mean they’ve been swimming further and further to reach their spawning grounds as the continents have separated, but I can’t think of any other explanation as to why a 1.5 year migration through a habitat far more dangerous than their freshwater home would evolve in such a species, unless the Sargasso Sea is the holy grail of baby eel sanctuaries.
New Zealand has a native eel which also spawns in the ocean, but it is still not known for certain exactly where in the Pacific that is. I have seen "Near Tonga" and "Near New Caledonia" mentioned.
Hank is one of my very favorite explainers, whether it's here, on SciShow, or Into the Microcosmos! Thank you, Hank, for all you do!

I've been waiting for a water creature to start my subscription to the pin club, and it's one of my favorites! Glass eel fishing is a big part of the economy where I grew up, hearing that it's often illegal or trafficked is...well...interesting, but honestly not surprising to me 😅 those babies can sell for thousands per pound, one fishing trip and you're rolling in the millions no joke 👀 for poor rural fishing towns that kind of money is no joke
Quite similar to the New Zealand longfin eel, which is a very long-lived fish, with records of females reaching 106 years old and weighing up to 24 kg. They migrate to the Pacific Ocean near Tonga to breed at the end of their lives.
Wow!
I already knew about how weird eel mating organs thanks to a Salmonella academy video about Sigmund Freud .

WHAT'S A N**** GOTTA DO TO GET SOME EEL DI-
During the International Geophysical Year (1956) researchers trawling in the Sargasso brought up a larval eel that was five inches long. As the usual eel larva is only 1/10th of an inch long, they calculated that if this larval form had grown to adulthood proportionally, the adult would have been 200 feet long. This would explain old sailors' tales about sea serpents in the Sargasso.
Prob the last one alive.
Delusional people
And maybe the Loch Ness monster.
On the other hand Japanese eels do have gonads and are also bred by authorities and farmers in the northern parts of the Philippines. They were originally brought there during World War Two when the Japanese occupied the Philippines. The area in the Cordilleras where they are farmed is famous for its rice terraces, and the farmers grow eels as well as rice in the same terraces. Apparently the eels are also beneficial to the rice plants, eating some insects that can damage the plants, and they provide extra income for the rice farmers.
I don't think that's correct, it seems all eel farms start with wild caught glass eels, i have not seen any credible claim of captive breeding, and i imagine rearing the oceanic planktonic larva is going to be a challenge even if were possible to get the adults to spawning physiology in a captive environment.
So they develop gonads on their way to the Sargasso sea, but when is it determined which gonads they get? Or are they hermaphroditic?
Good question!!!
They probably still have X or Y equivalents, it's just that they spend effectively 25 years going around before they hit "puberty"
@@Appletank8 there's quite a few fish that can switch between male and female depending on what's more beneficial, so I wouldn't count on that
Good question. I guess it just depends on how they feel at the time :D
@@Appletank8 There are what is sometimes called "W" and "Z" where both are required, but do not determine the internal gender of the offspring; gender is influenced by external factors such as: temperature during incubation; nutrient availability during larval/juvenile stage; local gender ratios during adolescent/adult stage. Some species do not deviate to a specific gender until just before becoming mature and participating during mating season(s); though most that follow such strategy often die just after mating/incubating eggs.
The glass eels have another name, they’re called elvers which I think is amazing. The Australian and surrounding countries eels are also just as strange and nobody is sure where or how they reproduce just that it’s somewhere near New Caledonia. I love finding them in the wild when I’m out filming for my documentaries, they can be so far up rivers that have multiple waterfalls and seemingly impassable terrain but somehow still get there
"The glass eels have another name, they’re called elvers" Did you even watch the video? It clearly shows that 'elvers' are the stage AFTER 'glass eels'. 1:15 🤦♂
So, if anybody is calling glass eels 'elvers', then they don't have a clue what their talking about, apparently just like you don't.
@@sunnyjim1355 you're wrong
I live in Europe and I’ve seen lots of eels when I was a child. My dad used to take me out fishing very early in the morning when the grass was still dewy. He used to fish in two ponds that were quite close together but separated by a grassland. In the early hours of the morning we could see the eels slider from one pond to the other. They do so to look for other feeding grounds. It’s quite a sight. Now sadly eels are an endangered species. It’s true that the glass eels are traded. Especially Chinese people think it’s a delicatesse.
Japanese eat em too but its ok if they do it
Nah it's mostly the Japanese who eats them. Unagi
You can try unagi sometimes it's delicious and expensive.
Do they call it scientific research like for their whaling activities.
Eels sound like the closest thing we have to actual Pokémon evolution 😂

We have known about this since the late 70s when it was filmed of eels spawning on Sargasso weed rafts, it was later they found out that Eels will use the natural ocean currents, Like they will arrive in Europe using the Gulf Stream, and they will use the North Atlantic Drift current to latch onto the Southern Gulf Drift current which takes them into the starting point of the Weed Rafts of the Florida Coast where they end up in the Sargasso Sea to spawn
I was taught that eels from Britain went to the Sargasso to breed in biology class at school in 1970-71.
I'm a little surprised to be told this has only just been discovered.
In all fairness, he never said that. The story is about tracking adult eels back to the Sargasso.
Many years ago I worked with a captain who had sailed around most of the worlds oceans on Supertankers.
He told us that a lot of eels are born or hatched in the Sargasso Sea, as he had talked to fishermen in that area who sometimes caught elvers (baby eel).
Maybe it was just a "fisher-mans" story, but who knows.
Glass Eels are called "Elvlings" and they are actually being poached RIGHT THIS WEEK IN NOVA SCOTIA!
party in nova scotia
There's this theory about eels going to the bermuda triangle (sargasso sea) to sacrifice themselves to the alien eel god (or satan perhaps) to create more eels. I liked that wacky theory since eels (especially morays) looks like it came out of lovecraftian horror.
Fascinating video about fascinating animals! A relative of mine is convinced that eels are endadgered due to US military equipment in the sargasso sea messing with the animals navigation system, as eels only recently got endangered, and they can only breed in one place.
I'm not so sure myself, but it'd be cool to understand why they need to go to the sargasso sea, and how they find their way there.
Eels: Unbothered. Moisturized, Happy. In my lane. Focused. Flourishing.
Humans: okay but why
Eels: Slightly bothered. Still moisturized. Probably happy? In a lane. Slightly distracted from this collar. Potentially flourishing.
Who else thought from the title that this was going to be a story about how we didn't know who the ancient dinosaur-era ancestors of the eels were, and instead found an even weirder story about how we didn't know where eels got their gonads?
Subscribed the second I heard Hanks voice. lol Any channel he is on is pure science gold and I'm here for it.
Soooo... that means basically we still don't know what an eel egg looks like?
American eels also spawn in the Saragaso sea. I remember when I was a kid all you had to do was throw your hook in a river and reel it in. You were almost guaranteed to have an eel on the line
Huzzah, it's silver eels all along.
All I can think of the Eel Song from Mighty Boosh...

Surely someone has kept eels in captivity to see their full life cycle, right? Why would that not have worked out? They just never reach the last stage if they don't make the journey to the Sargasso Sea?
I mean, they are migratory. It couls be that that last switch just never gets flipped, so to speak.
I have stopped eating eel despite liking it. Due to complex reproduction and life cycles, they can't really be farmed so they are actually just catching the wild baby eels and then growing them, but this is destroying their wild populations and the overall population is shrinking.
But the thing of them being born in the Sargazzo sea and spending their adult life in Europe was already known at least when I was a kid in the 80s.
It's interesting that they do the opposite of what the atlantic salmon does: living in the sea and migrating to the rivers to reproduce and die.
Don't forget the monarch butterfly.
Here's a thought: could someone use e-dna (environmental dna) to try and narrow down the specific spawning site? I know currents would make it complicated, but it'd be less expensive than disposable GPS tags
that would probably pick up the eel larvae that we know are there, not answer the questions about how and where exactly the adult eels spawn.
Thank you for the amazing video. Appreciate the research behind it.
It takes over a third to a half of a current human lifespan just to see them grow gonads!?! How have they not gone extinct yet!?! We eat so many of them!! Do they have a ton of eggs and most of them don't die die to predators and things!?! I have so many more questions that need answered now!!!
They are pretty endangered for many reasons (human reasons...😕)
I don't know any answers to your questions, unfortunately.
I'm deeply curious, too!
the IUCN lists them as critically endangered, which is one step away from extinction. apparently eels are in particularly desperate need of bans on catching or selling them, but the fishery lobby is successfully delaying regulatory action, and it's sort of generally failing to register that a fish that used to be so common and cheap is now in need of protection.
Oh my... I had no idea since they are sold everywhere for cheap... I really hope they get the help they need then soon so we can have our slippery slimy friends for a long time to come🥺😥💜 I really hate how governments can be essentially bought out since people work in governments, sometimes I think we'd be better off with literal monkeys in charge...
Well, we have lost ~98% of the European eel population in the last 35 years. Majority of the glass eels are caught to be raised and slaughtered in eel farms. And the general population has no idea because those farms market themselves as if they were breeding them.
But yes, they spawn a lot of offspring at once. It's why they lose the digestive tract during migration, to make room for as many egg/sperm cells as possible.
"Where do eels come from?"
Well, you see, when a mommy eel and a daddy eel love each other very much...
....they can't love each other just a little bit, they have to be in a committed relationship....
This works only for north Atlantic eels.
What about South Atlantic. North Pacific. South Pacific. Indian Ocean.
There are eels everywhere.
There was a Xena show where they were handling (in New Zealand) these brutes of eels, had to be 5 feet long and as big as your thigh.

It’s amazing that eels haven’t gone extinct and not amazing that many species are endangered.
Where do eels come from, where do eels go? Where do eels come from, yellow eel Joe
I feel like a few years back we discovered an insect that we thought was two different species ending up being a life cycle stage. So interesting we finally connected the dots with eels too
No one:
Sam O’nella: 0:27 “WHATS A N-“
A Devonshire farmer told me couple of years back that eels don't die until after 12 o' clock on the day they're caught. Even if you cut them up and put them in the fridge they quiver and twitch until seconds into the new day.
They wait until a storm and then cross from one field to the next by thunder and lightning.
On Christmas Eve when the other animals kneel down at midnight to herald the birth of Our Saviour eels and ravens congregate in the graveyard.
My hovercraft is full of eels.
Eels descended from the Goa'uld. Everything Stargate fan knows this through and through!!!
The first fish I ever caught was an eel in the St. John's River, Florida, around 4 years old.
I had no idea eels don't have reproductive organs for most of their lives, and that growing them kills them eventually. That really IS bizarre.
The north american freshwater eel is also a mystery. They are born way upstream in very shallow creeks and travel downstream all their lives. No one knows how the eggs get upstream in the first place. The adults never go back.
Continental drift was a main factor in eel evolution. It is believed the common ancestor of eels lived east of the supercontinent Pangaea, in the Tethys Ocean (present day Indonesia). The ancestral eel, like modern eels, must have made regular migrations between its spawning region in the ocean and its nursery areas in the rivers. As the northern part of Pangaea separated from the southern part, the Tethys Ocean was connected with the sea in the east with the sea in the west. The ancestral eel was thus able to spread into the western sea.
I remember being in college around 2015 and hearing my ichthyology (fish science) professor say with a straight face that we don't know where eels breed. "Somewhere in the Atlantic" was as close as we had narrowed it down. Still blows my mind.
This is the best RUclips video this year, of something I didn't know I needed to know.
I think that I, on a Danish Cemetery, saw a sign that this person had been the one to find out that the eels migrated to Sargasso to make new and small eels!

Dude. I was pondering about eels just yesterday. Great timing. Wonderful.
my favorite was aristotles attempt on solving the myth. he said when thunder claps is when eels reproduce.
You really could just say whatever back then
I went to school in Cornwall 1947-1953 and was taught exactly this !!!!!!
I know all those scientists working on that paper must’ve been beaming to solve such an old mystery
Fascinating, although it leaves the impression that we are talking about eels in general, instead of only two species of the many varieties.
I love that humans were so focused on “Where do the eels come from?!?!” We literally researched this for a few hundred years to find out.
That's it? We've FINALLY known all of that for a few decades now.
Anyone who read Graham Swift's Waterland will be hugely relieved to learn all this. It's been 40 bleeding years we've been waiting for the resolution of that plot element.
I always hear about "We only know about 10% of our oceans" but now seeing how only last year people understood how an animal life cycle works, makes this claim way more evident in my mind now.
I can't be the only one that rememberd Sam O'Nella's memorable quote... with Sigmund Freud... and Eeels?
the fact we didn't find out how eels reproduce untill just last year is insane but also not because eels are ridiculous
My 38 year old son has a pet eel,he saved from being bait. His name is Eli and i call him my sliny grandson! 😮😮😮 Hes very cute and sweet and about 10 yrs old! Now i know more about him. Thanks!❤❤❤
Finally! A video actually worthy of an up-thumb. Cool
I still have questions…
1) Do we have enough information to simulate this long migration process and reproductive end cycle in the lab? If not why? There are theories that this has to do with salinity adaption, stress, oceanic pressure adaption, and even the phases of the moon. Which are causal and which are coincidental?
2) You mentioned physiological changes in the eels late stage reproductive cycle. Do we know why they must travel to these specific locations?
3) other catadromous fish such as the Australian greyling reproduce near the mouths or rivers and estuaries instead of the depths of the ocean. Why is this? How do they differ from eels?
4) Does this reproduction process shorten their life span? In other words would they live longer if they had not gone through this stressful migration and adaption but never reproduce? Or would they actually be able to reproduce? Would not making it the full mean they are fertile but have no other eels to mate with given the variability of their location to the spawning area. Thus making their reproduction meaningless.
Really appreciate that your long answer was only 6 minutes Hank.
Thank you
👍👍
I did not know that eels were this mysterious and now I know.
How have I never heard of this channel?????
I found a glass eel in a river as a kid while hunting minnows it was nearly invisible, i also found a pink eel in a rock pool when i was around 8 it was the lenth of my arm and as thick as my wrist.
Thank you for not making us a crazy science fiction history I really appreciate your channel and what it does
I just want to thank the countless men and women who work most of their lives to uncovering the secrets of how eels do it. Science is so very important, especially in the world where people lie about what they eat in the morning.
