I remember seeing a photo of these at an aquarium as a child. It actually gave me nightmares and to this day I am still terrified of these things. Thankfully they live in the deep!
It is filmed in seawater in a special round tank aboard a research ship - yes it's not well because trawled from nearly a mile down. The increase in temperature and mechanical damage of the net are what kills it, but it's really tricky to film deep sea creatures without huge resources for submarines or large ocean going ships that can trawl or send ROVs down with cable connections.
It's acctually not dead its just that it's very rare that it gets a good meal so in order to preserve its calories and energy it moves as little as possible
You are a great observer. This is mechanical damage (a rip) from being trawled up from the deep. Sadly it is tricky to see these creatures - you either spend a lot on a scientific research ship with a trawl (cost about $2 million per month) or get some research subs (cost $5 million a month upwards - $30,000 per dive). Also given that these creatures live in the OPEN ocean they never encounter hard surfaces (in the mid water anyway like this creature), so they don't have to have strong skin - they don't bump into things much. Yellow fin tuna young (fry) have only one or two cells skin thickness for example - that's why farming them has proved difficult - they hurt themselves on the pens very easily.
Ah, yeah, I’ve heard about stuff like this when it comes to keeping open ocean animals in captivity. White sharks specifically. They have a tendency to bump into their enclosure and quite possibly hurt themselves.
Seeing the gill placement and structure @1:48 is absolutely fascinating. I love gulper eels to the extent that I have a tattoo that covers most of my thigh of an alien-esque gulper eel that would make the eldritch gods smile.
u also need to remember that it is adapted to live under extreme pressure and weight and the pitch black so being under almost none and under bright lights is probably doing no good for it
Yes it is a different eel. No it doesn't inflate like a balloon. The eel filmed by the Nautilus is a genuine Eurypharynx pelecanoides. This one is a Saccopharynx sp (probably S. lavenbergi) so different species, genus and family. Saccopharynx can't expland its gular pouch to the same extent as Eurypharynx, but it does have a larger, distendable belly and bigger teeth. = ruclips.net/video/vYyizW-U1fQ/видео.html
Thanks - it's pretty difficult to get to species level and I imagine there are only a few people in the world who know. S. lavenbergi does indeed have a distribution that includes California where this one was found, although the depth of this trawl at 600m was considerably higher than mentioned in this Fishbase entry: www.fishbase.de/summary/57197. I think it was a night trawl so vertical migration might account for that?
This isn't Eurypharynx pelecanoides. It's a Saccopharynx sp (both are called Gulper eels). Eurypharynx has minute teeth, while the eel in the film has well developed teeth (0:28)
Pelican eel are the ones with the stingray body looking jaw and the gulper eel is the one that looks like a wide tube right also I can’t tell what this one is because it has the Jaw structure looking thing could be please clarify I’m a bit confused on which ones which
Caught off San Clemente Island, California if that helps. There is some contradictory information in the reference books about them but will research again and report back
That is really great - me too and I just wrote a book about it! (www.amazon.co.uk/Whale-Your-Living-Room-documentary/dp/1472143507/ref=sr_1_1?dchild=1&keywords=THe+whale+in+the+living+room&qid=1619385978&sr=8-1)
I agree, and the place where it lives. We need technological advances such as a cheap drone that works underwater without cable. Unfortunately that's tricky because the radio signals needed to control it are absorbed by water. People are experimenting with light beams to control an untethered underwater drone but they only have a limited range. Cable is too restrictive and needs an expensive cable ship if you are going to average sea depths of about 2 miles. It's about $40,000 A DAY to do that at the moment.
Yes they are very delicate like many open ocean fish that never touch any surface and can have very thin skins ~ so trawling for them is very damaging ~ surprising how this one is pretty well preserved considering
Well the one we filmed was in the Pacific off California but does look pretty similar to Saccopharynx ampullaceus, which is a north Atlantic species I think. Maybe not so square shaped and a bit smaller with a more slender body - but that could depend on what it has recently eaten as they are very flexible! Not sure I have our species name is exactly right though - Eurypharynx pelecanoides - but maybe a Californian area sub species?
It has a circular flow and is called a 'kreisel' tank - it is used for delicate creatures that should not touch the sides. Aquariums that show jellyfish often use them. Open ocean creatures do not ever usually touch any hard surface because there is so much open water and so many often don't bother having a tough skin. It works well for lighter creatures - not so well for big fish. You can read more about these types of aquariums here: fishlarvae.org/equipment-techniques/plankton-kreisel-tank/
It seems to be similar to the insides of many fish gills but also seems to have an intense red color suggesting high levels of oxygen absorbing pigments like hemoglobins ( compare for example with bloodworms that live in low oxygen environments) but no one knows as it is so rare to find one even partly alive- you are right in thinking that deep water is low in oxygen
@@IndoonaOceans Well I can def get behind that theory as several species of deep water sharks. Cat-sharks, 6/7 gills, and the frilled shark come to mind especially. Guess now we need to learn how something with a jet black color, virtually non existent eye sight, and a missing swim bladder makes more of itself thousands of feet down….the mysteries of the deep :)
If you mean the surface of the ocean then that is how we filmed them. Only the mouth which can balloon when alive is a bit floppy. The actual skin surface is like velvet and the inside of the black mouth even more so.
I think it is 'air sack' - I was talking about the 'swim bladder' that many fish have to control their buoyancy - as you go down the pressure of water gets much more intense and if you have air in any cavity then it will be shrunk as the pressure increases. Fish in shallow water can adjust this by having an internal air sack or swim bladder that they can expand or contract with their muscles I think and so compensate for the changes in buoyancy as they go deeper. Being able to float at any depth is great because it means you don't have to waste energy swimming. SO that works until you come up and the air expands again making the fish potentially much more buoyant and it might shoot to the surface and get eaten by a seabird say, or get tissue damage from sudden pressure change, if it doesn't compensate by squeezing its swim bladder to increase the pressure of this air sack and reduce buoyancy. That works OK in the shallows but if you come up from 600 metres like this gulper eel could - you'd likely explode the air sack (swim bladder). So many deep sea fish, like the gulper eel, don't have the swim bladders shallow water fish do because they would be more of a pain than a help. As you know liquids cannot be compressed like a gas so if you eliminate all gas pockets in the body then pressure changes are not so harmful.
But i see in that tank deep sea fishes being alive did they put pressure in that tank? because these types like that fangtooth fish live in deep pressure or can they just survive without pressure?
I think it is how roughly it is treated in the net - it is unavoidable to hurt it if caught that way in a trawl net - the only other way would be to catch it with a mini submarine and suck it into its tank. But that is usually far too expensive and it's difficult or near impossible to find such a fish with a submarine (especially if they have bright lights on them). You are right about the pressure differences and the extreme pressure in the deep sea but many fish like this have lost any air cavities and their body is entirely fluid - as you know fluid does not for all practical purposes expand or contract - only gas and if it has no gas in the body then it is OK. For this reason many deep sea fish do not have a 'swim bladder' the organ used for keeping buoyancy that is filled with gas. However, I think there are some limits for extreme pressure differences as it is probably impossible to eliminate all gas pockets. The Monterey aquarium in the USA has kept deep sea fishes for some time but have all the experts and a research team with submarines and ROVs at MBARI - Monterey Bay Research Institute. They also keep the tanks very cool - it is about 4 centigrade at 600m where these fishes live. Hope that helps explain!
So water cuts out light as you probably know, especially red light, which is why it soon goes blue as you dive. At about 50 metres- the human limit for diving on air it is a darkish shade of blue. At about 1000m it is almost black and at 2000m I would say black ( this eel was caught at 600m). BUT it depends on how much light is coming from the surface. On a bright day with the sun overhead at mid day if you had a very sensitive camera you’d likely be able to detect the sun at say 1000m down. I have been involved in a project filming at night off the Azores using ultra sensitive starlight cameras. We filmed in full moonlight and on days with no moonlight ( new moon). On the full moon days we could detect moonlight down to 500m but we couldn’t see anything on new moon days - so light at depth depends on the level of surface illumination- obviously really but you don’t think about it until you try to sample the light at depth.
It kinda has that creepy but fascinating feel of dilpcaulus doesn't it? However, only a zoology would think that perhaps: Diplocaulus - en.wikipedia.org/wiki/Diplocaulus
It's a round tank with a circular water flow called a kreisel - often used for jellyfish and it stops them sticking on the front glass - tends to keep lighter fish at least in mid water.Open ocean creatures never experience surfaces to bump into.
It's the filming tank . - a special one called a kreisel - you see the wide shot and there are a few trawled animals in it including a vampire squid . - immediately before 2.41 is a little microscopic plankton animal called a copepod. You can see more in the video 'How We Filmed A Dragonfish' on the Indoona channel and here is something about kreisel aquariums: www.practicalfishkeeping.co.uk/gear/review-schuran-kreisel-tank/
@@klttrll There is one actually ruclips.net/video/eet0jlMXJ5M/видео.html although those poor squids are pretty soft and don't survive the trawling for long
Yes I know what you mean! A lot of deep sea creatures look scary but in fact they are mostly pretty small (except for the giant squid etc. and anything else we may still find!)
And they can puff up their mouth & heads like a balloon. A defensive measure to appear bigger, when it encounter these submersibles. How did you captured alive? And how long did it survived in the tank. I didn't know these could be captured alive.
Thanks for the comment- I think it had recently died. It’s mainly because of mechanical damage in the trawl net - although the change in temperature and pressure as it comes to the surface relatively suddenly doesn’t help. Actually I suspect that on moonless nights it would come much nearer the surface of its own accord. There is a great video of it showing the balloon mouth you suggest- I will find the link and post it here. In that it seems to be ballooning as part of predation- maybe the increase in mouth volume sucks in prey - but I hadn’t thought of it as defense - I will look again. It is of course usually almost completely dark at its depths so perhaps visible signs of being big don’t matter?
Here is the link I mentioned:ruclips.net/video/ph6R0yY2WzI/видео.html - you can see the ballooning 35 seconds into the video- beautifully filmed by the Rebikoff Foundation in the Azores - a couple who run a submersible and have some astonishing images
@@IndoonaOceans Thanks! There was a time I was fascinated with deep sea creatures but eventually my fascination turned to other subjects: carnivorous plants & corpse flowers.
That’s a very good question and observation. As you say the oxygen content is low at these depths although the cold somewhat helps as gas saturation is proportional to temperature and more O2 will dissolve into cold rather than warmer water. Increased pressure helps force more gas into solution too. However, between about 200-1000m there is something called the oxygen minimum layer as you probably know, and I guess this is where the surface is far enough away to stop atmospheric mixing but not quite cool or pressurized enough to help oxygen saturation. That’s just the depths where these mid water creatures live. Although low oxygen it’s not no oxygen and these fish likely have adaptations to make the best of it. I noticed how very deep red the gulper eels’ gills are and how relatively long and large. The deep pigment reminds me of bloodworms that live in anoxic mud and if I remember rightly have special hemoglobins- oxygen carrying molecules- sort of supercharged to make the best of the little oxygen there is. Although I don’t know if the blood of the gulper eel has been analyzed I wouldn’t be surprised if something similar is going on Also they may well have other adaptations like special ways to ventilate their gills ( the fangtooth does) .There’s more in papers like this on the oxygen in the sea:www.sciencedirect.com/topics/earth-and-planetary-sciences/oxygen-minimum-layer And for more details of hemoglobin in other deep sea invertebrates and fish - which seems to suggest it varies a lot by species and that in some there is no difference between shallow and deep water kinds (but deep water fish often have low metabolism and are slow growing too therefore). journals.biologists.com/jeb/article/206/15/2693/20251/Hemoglobin-function-in-deep-sea-and-hydrothermal On bloodworms: www.wattylereducation.info/index.aspx?articleid=3524#:~:text=Adaptations%3A%20'Bloodworm'%20(red,species%20build%20case%20for%20protection.
@@IndoonaOceans thank you so much for the detailed answer! I love it ❤ I asked because I was wondering if all creatures on Earth breathe. So the answer is yes, but except of viruses, which just feed. It's for a coding exercise. It makes sense that these creatures deep in sea are beautiful red, since they cling on to these supercharged hemoglobins like their life depends on it - because it does :)
I'm amazed to see that there are creatures that are actually alive, swimming around in the water. Are they from the deep sea too. Also do you know much about the Gulper Eel's gills, and is this a male or female?
Hi - I don't know the sex of this fish - maybe there are specialists looking at this who can tell us please? The gills look very extensive and the fish lives in mid water depths , probalby about 600m average, where the oxygen levels start to go down so I am guessing that they have to be pretty efficient. Although the open and deep sea is quite sparsely populated with fish there is so much of it that the fish there form much of the total life on Earth.
Well my mum is Austrian and my Dad was Scottish but pretty English really and I grew up in Wales and lived in Germany, USA, Singapore and New Zealand for anything between three months to a year so who knows! Well spotted!
Gulper or Pelican Eels are deep sea creatures that need, the heavy water pressure in their natural environment to survive. Most all deep sea creatures that are taken from their natural environment die, due to the change in water pressure that they endure. So unless they made tanks that can mimic or make the heavy water pressure that they live in, you could never have a Gulper Eel or any deep see creature as a pet. They would also need to make special containers for capturing these creatures that could make the conditions of their environment, so they don't die during capture. This is why national aquariums can't have deep sea animals on display.
Like it! It is just that other way of thinking that will get you far and can change the world. I guess it's because we became aware as a species only 160k years ago or so and almost all of that without seeing beneath the oceans - so we were bound to see pelicans first before deep sea creatures. Of course all animals here today are by definition modern day creatures, with common ancestors but not evolved from each other ( so we are not evolved for example from chimpanzees but we both share a common ancestor, as you know). I suspect as you suggest some creatures and plants are nearer their common ancestors than others however, when there is little change in their environment (like the deep seas) and if they are a successful organism in that environment they hardly need to change much (except to combat pathogens perhaps) e.g. sharks, dragonflies, or horsetail ferns are all incredibly like their fossils hundreds of millions of years ago, to name but a few. So likely the gulper eel is closer to vertebrate ancestors than most.
have a look at the video on how it was filmed - ruclips.net/video/zYNBDJjZlLQ/видео.html - it is a record and unique footage othis creature. Thanks for you interest and I think it is important that we know what is on our planet to ultimately be able to protect it!
Sort of - nearly or recently dead. It is difficult to catch such fish without killing them as they come from very deep where it is cold. They are fragile and the trawling net damages them. Pressure isn't the main problem I don't think as they are adapted by not having air spaces, so no gas to exapnd when they come up.
Yes I agree with you - and I explain on another clip how it was caught for a science expedition and I thought at least we can film it for thousands of people (actually getting on for half a million counting all videos on the dragonfish on this channel) so that more learn about the sea and the extraordinary life it holds. Sadly too thousands of tons of fish are taken from the sea alive by trawl nets for our food.
Ive eated a few deep sea fish but i wouldnt try this one because ive eated a predatory fish and got sick also tasted bad.Theyr usually eyther verry tough almost like a steak in consistency or verry fat and bitter.Beware that somme might even be poisonous so its not just the fat that gets you sick.
YO IM WATCHING ONE PIECE RN AND THEY JUST GOT LOST IN THE DEEP SEA AND I WAS THINKING ABOUT HOW SCARY DEEP SEA WAS AND LANDED ON THIS VID IM SORRY IM SCREAMING ITS JUST SUCH A COINCIDENCE
I understand how you feel, and thanks for raising this important ethical issue. The trawling technique and the way this was filmed on a scientific expedition, is fully disclosed in both video, description and in replies to comments on this channel. My own view is that it would be shameful not to show this unique creature, in detail, to a wider audience than scientific researchers, given that this creature was not caught to be filmed but for scientific study. As explained elsewhere it is hugely costly to explore the deep sea and you can either trawl or use a submarine. Each of these methods is problematic. The use of deep sea trawls is cheaper but still can run an overhead of U.S. $30,000 , and more, a day depending on the ship, and sadly will kill delicate deep sea creatures, even those from relatively shallow depths like this one from 600M. This is mainly due to the mechanical damage of the net rather than pressure differences as deep sea fish have great adaptations to avoid pressure problems, although temperature differences are often lethal too as deep water is very cold and the surface very hot to these fish. So the fish shown here was recently dead. It has, however, been seen now through this channel over half a million times and hopefully adds to our understanding of the amazing creatures from the deep sea with which we share our planet - so it's great publicity for the sea if you like. The bigger picture is that marine research is woefully underfunded, considering the ocean's importance to the world and our urgent need to understand it. If the Indoona channel can do even an infinitesimal amount helping understand that, then it is not in vain.
Watch this video which explains how difficult and expensive and rare they are to see: Gulper eel caught on camera - gulper, or pelican eel and how we filmed images never seen before ruclips.net/video/zYNBDJjZlLQ/видео.html:

We did not add pressure to the tank - the animals lived for a few hours but died I think mainly from injury during trawling in the nets
@@IndoonaOceans good to know, thx for the responses
Wow. Just spectacular.
Thanks glad you liked it - what else would you like to see in the deep ocean?
That is adorable

How deep does an Eel have to be for there to be no light?
So water cuts out light as you probably know, especially red light, which is why it soon goes blue as you dive. At about 50 metres- the human limit for diving on air it is a darkish shade of blue. At about 1000m it is almost black and at 2000m I would say black ( this eel was caught at 600m). BUT it depends on how much light is coming from the surface. On a bright day with the sun overhead at mid day if you had a very sensitive camera you’d likely be able to detect the sun at say 1000m down. I have been involved in a project filming at night off the Azores using ultra sensitive starlight cameras. We filmed in full moonlight and on days with no moonlight ( new moon). On the full moon days we could detect moonlight down to 500m but we couldn’t see anything on new moon days - so light at depth depends on the level of surface illumination- obviously really but you don’t think about it until you try to sample the light at depth.
surprisingly unbelievable
Look no further than nature for things outside your wildest imagination
is it aggressive or friendly 🤔
Not aggressive at all - very soft body. The fang tooth went for us though - see in other clips on this channel.
@@IndoonaOceans ok thank you
Why does the gulper eel remind me of the dilpcaulus?
Kentucky Fried Elephant Diplocaulus*
Oof sorry
It kinda has that creepy but fascinating feel of dilpcaulus doesn't it? However, only a zoology would think that perhaps: Diplocaulus - en.wikipedia.org/wiki/Diplocaulus
Can anyone say what the name of the holding tank is called... ty
It's a round tank with a circular water flow called a kreisel - often used for jellyfish and it stops them sticking on the front glass - tends to keep lighter fish at least in mid water.Open ocean creatures never experience surfaces to bump into.
2:41 what all is in there
It's the filming tank . - a special one called a kreisel - you see the wide shot and there are a few trawled animals in it including a vampire squid . - immediately before 2.41 is a little microscopic plankton animal called a copepod. You can see more in the video 'How We Filmed A Dragonfish' on the Indoona channel and here is something about kreisel aquariums: www.practicalfishkeeping.co.uk/gear/review-schuran-kreisel-tank/
Why didn’t you do a video of the vampire squid
@@klttrll There is one actually ruclips.net/video/eet0jlMXJ5M/видео.html although those poor squids are pretty soft and don't survive the trawling for long
Is it dead...?
Recently dead yes please see ‘how we filmed’ videos for this and the dragon fish
It looked like a giant creature . Till the hand showed up.
Yes I know what you mean! A lot of deep sea creatures look scary but in fact they are mostly pretty small (except for the giant squid etc. and anything else we may still find!)
Never knew they were so small
And they can puff up their mouth & heads like a balloon. A defensive measure to appear bigger, when it encounter these submersibles. How did you captured alive? And how long did it survived in the tank. I didn't know these could be captured alive.
Thanks for the comment- I think it had recently died. It’s mainly because of mechanical damage in the trawl net - although the change in temperature and pressure as it comes to the surface relatively suddenly doesn’t help. Actually I suspect that on moonless nights it would come much nearer the surface of its own accord. There is a great video of it showing the balloon mouth you suggest- I will find the link and post it here. In that it seems to be ballooning as part of predation- maybe the increase in mouth volume sucks in prey - but I hadn’t thought of it as defense - I will look again. It is of course usually almost completely dark at its depths so perhaps visible signs of being big don’t matter?
Here is the link I mentioned:ruclips.net/video/ph6R0yY2WzI/видео.html - you can see the ballooning 35 seconds into the video- beautifully filmed by the Rebikoff Foundation in the Azores - a couple who run a submersible and have some astonishing images

@@IndoonaOceans Thanks! There was a time I was fascinated with deep sea creatures but eventually my fascination turned to other subjects: carnivorous plants & corpse flowers.
Katakuri ??
Perhaps so…
May I ask if these deep creatures are breathing? Since so deep there is almost no oxygen.
That’s a very good question and observation. As you say the oxygen content is low at these depths although the cold somewhat helps as gas saturation is proportional to temperature and more O2 will dissolve into cold rather than warmer water. Increased pressure helps force more gas into solution too. However, between about 200-1000m there is something called the oxygen minimum layer as you probably know, and I guess this is where the surface is far enough away to stop atmospheric mixing but not quite cool or pressurized enough to help oxygen saturation. That’s just the depths where these mid water creatures live. Although low oxygen it’s not no oxygen and these fish likely have adaptations to make the best of it. I noticed how very deep red the gulper eels’ gills are and how relatively long and large. The deep pigment reminds me of bloodworms that live in anoxic mud and if I remember rightly have special hemoglobins- oxygen carrying molecules- sort of supercharged to make the best of the little oxygen there is. Although I don’t know if the blood of the gulper eel has been analyzed I wouldn’t be surprised if something similar is going on Also they may well have other adaptations like special ways to ventilate their gills ( the fangtooth does) .There’s more in papers like this on the oxygen in the sea:www.sciencedirect.com/topics/earth-and-planetary-sciences/oxygen-minimum-layer
And for more details of hemoglobin in other deep sea invertebrates and fish - which seems to suggest it varies a lot by species and that in some there is no difference between shallow and deep water kinds (but deep water fish often have low metabolism and are slow growing too therefore). journals.biologists.com/jeb/article/206/15/2693/20251/Hemoglobin-function-in-deep-sea-and-hydrothermal

@@IndoonaOceans thank you so much for the detailed answer! I love it ❤ I asked because I was wondering if all creatures on Earth breathe. So the answer is yes, but except of viruses, which just feed. It's for a coding exercise. It makes sense that these creatures deep in sea are beautiful red, since they cling on to these supercharged hemoglobins like their life depends on it - because it does :)
If you look at it long enough it looks like it is smiling
Sadly it's not happy though - trawled up from 600metres
dude, this is cool
Yes what strange creatures we share the planet with. Mind you they probably think that about us!
i guess you could say this is the “pog fish”

I toght the same but after watching more carefully i think its an eel because of the tail.
Well it looks like a snake but is actually a relative of the eels
Love this place coming from Alaska
Thanks you - you are very welcome
I'm amazed to see that there are creatures that are actually alive, swimming around in the water. Are they from the deep sea too. Also do you know much about the Gulper Eel's gills, and is this a male or female?
Hi - I don't know the sex of this fish - maybe there are specialists looking at this who can tell us please? The gills look very extensive and the fish lives in mid water depths , probalby about 600m average, where the oxygen levels start to go down so I am guessing that they have to be pretty efficient. Although the open and deep sea is quite sparsely populated with fish there is so much of it that the fish there form much of the total life on Earth.
Where are you from bro ? Your accent is like Scottish mixed with American or something 🤣
Well my mum is Austrian and my Dad was Scottish but pretty English really and I grew up in Wales and lived in Germany, USA, Singapore and New Zealand for anything between three months to a year so who knows! Well spotted!
@@IndoonaOceans interesting , thanks for the information buddy 👍
;-; want one as a pet
Cody mach3 sadly they don't like light
My friend caught one a few months ago on a fishing trip. He has a massive fish tank in his basement which is pitch black and he keeps it there.
Gulper or Pelican Eels are deep sea creatures that need, the heavy water pressure in their natural environment to survive. Most all deep sea creatures that are taken from their natural environment die, due to the change in water pressure that they endure. So unless they made tanks that can mimic or make the heavy water pressure that they live in, you could never have a Gulper Eel or any deep see creature as a pet. They would also need to make special containers for capturing these creatures that could make the conditions of their environment, so they don't die during capture. This is why national aquariums can't have deep sea animals on display.
@@l04d83 Are you sure it was a deep sea Gulper Eel that your cousin caught?
Would make a very good video if he still has it!
Eel = Long Fish
true!
Hes like aaaaaaaa
Yeah ~ wouldn't be much point going to the dentist though!
If all living creatures evolved from fishes, then why do we call this a pelican eel and the pelican is not the gulper bird
Like it! It is just that other way of thinking that will get you far and can change the world. I guess it's because we became aware as a species only 160k years ago or so and almost all of that without seeing beneath the oceans - so we were bound to see pelicans first before deep sea creatures. Of course all animals here today are by definition modern day creatures, with common ancestors but not evolved from each other ( so we are not evolved for example from chimpanzees but we both share a common ancestor, as you know). I suspect as you suggest some creatures and plants are nearer their common ancestors than others however, when there is little change in their environment (like the deep seas) and if they are a successful organism in that environment they hardly need to change much (except to combat pathogens perhaps) e.g. sharks, dragonflies, or horsetail ferns are all incredibly like their fossils hundreds of millions of years ago, to name but a few. So likely the gulper eel is closer to vertebrate ancestors than most.
Is it wrong that I like this creature?
no!
Rumors said you replies comments. Are you?
Yes if you would like to ask a question I will try to answer

That first eel is dead ;_; stop playing with its dead body, sad
have a look at the video on how it was filmed - ruclips.net/video/zYNBDJjZlLQ/видео.html - it is a record and unique footage othis creature. Thanks for you interest and I think it is important that we know what is on our planet to ultimately be able to protect it!
This is a dead specimen right
Sort of - nearly or recently dead. It is difficult to catch such fish without killing them as they come from very deep where it is cold. They are fragile and the trawling net damages them. Pressure isn't the main problem I don't think as they are adapted by not having air spaces, so no gas to exapnd when they come up.
I dont like that one side of his upper jaw isnt actually attached to his lips...
Yes I agree with you - and I explain on another clip how it was caught for a science expedition and I thought at least we can film it for thousands of people (actually getting on for half a million counting all videos on the dragonfish on this channel) so that more learn about the sea and the extraordinary life it holds. Sadly too thousands of tons of fish are taken from the sea alive by trawl nets for our food.
How does it taste if cooked? :)
fishy
I want to know to the same thing
Ive eated a few deep sea fish but i wouldnt try this one because ive eated a predatory fish and got sick also tasted bad.Theyr usually eyther verry tough almost like a steak in consistency or verry fat and bitter.Beware that somme might even be poisonous so its not just the fat that gets you sick.
Like shit im sure.
How about prolong its life
terrifying
a little perhaps but too small really
If it a giant version of this creature in the sea ah hell nah am about of here
Yes is would be but you can see its size against the hand - and a lot of frightening deep sea creatures are pretty small like this e.g. angler fish

@@IndoonaOceans yes
Waving around a dead fish as if it was alive. Shameful.
I understand how you feel, and thanks for raising this important ethical issue.
The trawling technique and the way this was filmed on a scientific expedition, is fully disclosed in both video, description and in replies to comments on this channel. My own view is that it would be shameful not to show this unique creature, in detail, to a wider audience than scientific researchers, given that this creature was not caught to be filmed but for scientific study.
As explained elsewhere it is hugely costly to explore the deep sea and you can either trawl or use a submarine. Each of these methods is problematic. The use of deep sea trawls is cheaper but still can run an overhead of U.S. $30,000 , and more, a day depending on the ship, and sadly will kill delicate deep sea creatures, even those from relatively shallow depths like this one from 600M. This is mainly due to the mechanical damage of the net rather than pressure differences as deep sea fish have great adaptations to avoid pressure problems, although temperature differences are often lethal too as deep water is very cold and the surface very hot to these fish. So the fish shown here was recently dead. It has, however, been seen now through this channel over half a million times and hopefully adds to our understanding of the amazing creatures from the deep sea with which we share our planet - so it's great publicity for the sea if you like.
The bigger picture is that marine research is woefully underfunded, considering the ocean's importance to the world and our urgent need to understand it. If the Indoona channel can do even an infinitesimal amount helping understand that, then it is not in vain.
