Scientists solve mystery of why thousands of octopus migrate to deep-sea thermal springs

- Deep below the ocean’s surface just off the Central California coast, thousands of octopus gather near an extinct underwater volcano. The Octopus Garden is the largest known aggregation of octopus anywhere in the world.
Researchers from NOAA’s Monterey Bay National Marine Sanctuary and Nautilus Live first observed thousands of pearl octopus (Muusoctopus robustus) nesting on the deep seafloor near Davidson Seamount in 2018. Their discovery captured the curiosity of millions of people around the world, including MBARI scientists. For three years, MBARI and a team of collaborators used high-tech tools to monitor the Octopus Garden and learn exactly why this site is so attractive for deep-sea octopus.
Using cutting-edge technology-including many instruments designed by MBARI engineers-MBARI researchers and our collaborators from NOAA's Monterey Bay National Marine Sanctuary, Moss Landing Marine Laboratories, the University of Alaska Fairbanks, the University of New Hampshire, and the Field Museum confirmed that Muusoctopus gather at the Octopus Garden to mate and nest.
Female pearl octopus nest in cracks and crevices bathed by warm water. Warmth from deep-sea thermal springs accelerates the development of octopus eggs. Scientists believe the shorter brooding period increases a hatchling octopus’ odds for survival.
The size of the Octopus Garden-likely more than 20,000 total octopus nests-and the abundance of other marine life that thrives there underscores the need to understand and protect hotspots of life on the deep seafloor from threats like climate change and seabed mining.

The octopus garden is so beautiful, it really is a priviledge to see it.
We truly must protect the incredible life under the sea. Thank you MBARI for your important work.
Yes its essential for all life on the planet! ❤ hope you are having a great day!
We can barely protect the people on land let alone the people that breathe the same air as everyone else
A volcanic octopus kindergarten! What a time to be alive. ❤
Thanks Dr. Barry for this update. I can't believe it's been 3 years since the first couple of passes when many of us watched live, with bated breath, for researchers to locate and explore the mysterious octopus gardens. I'm happy to hear how much interesting research has come out it since, and I enjoyed this quick catch-up summary.
Two of the finest things ever given to man to enjoy: the Octopus and almost any program about what is up in the oceans. Ty for keeping this about sea critters and not about political topics that people meander through.
I'd like to be...under the sea...
In an octopus's garden :)
In the shade
Idk… there’s some freaky and scary looking fish down there.. 😱
The song immediately came to my mind too.

It’s dreadful to think how many beautiful and unique marine sanctuaries humans have unknowingly trawled into oblivion.
Intresting ! We are lucky to see science progressing in direct. Thanks !
This is so interesting! Nature is amazing.

This is so awesome i cant wait to hear more about what they may learn at the other octopus garden site in Costa Rica! The previous expedition that was there with the Schmidt Ocean Institue was an amazing experience! I really wish that MBARI would stream their ROV dives like some of the other programs like The Nautilis, Okeanos explorer, and Schmidt!
Thank you for doing this important work 🙏🏻
NPR ran a story about this on air earlier today, really amazing stuff. Wonder what the octopuses think about these alien submersibles. They seem really unperturbed.
One of My top 5 animals...
Amazing! Anyone else tickled thst the OCTOpus sanctuary was discovered in OCTOber?
Just me? Nevermind 😅
simply marvelous how they use the vents like that.
Was it you who followed the octopus mom over 5 years as she protected her brood in deep cold waters?
Yes (but it was 4 years, not 5)! That was another species of deep-sea octopus that we found in the Monterey Canyon: ruclips.net/video/lFCQltYMLQk/видео.htmlsi=Q4Id7H7kILBCfw0C
@@MBARIvideo Yes, I knew it was a different species, thanks for the info!

@MBARIvideo,, and aren’t octopus generally solitary creatures? I think that’s what makes this so incredible. Since they pretty much don’t eat after they lay their eggs (because they have to protect their eggs from predators, and they have no other mates or companions to help out protecting the eggs or providing food), I wonder if grouping together like this actually allows them to eat, as it is much less likely predators will attack when there is an entire group of octopus as seen here. This likely also decreases their stress level, and allows them to rest more, too. It makes me really wonder whether octopus have developed to become a bit more social! Any thoughts or knowledge about whether they are eating, or whether anything else about them being grouped together, besides water is allowing the eggs to hatch more quickly?
@@thenoises1604 humans cannot rationalise.
Hydrothermal vents has many more qualities, hope you will make more videos about that.👍❤️
The push for deep sea mining is terrifying.
One more reason to push asteroid mining.
Fascinating and fantastic MBARI Thanks again to everyone for your time and effort.👍🐙👌
Interesting. Considering the ocean waters are getting warmer maybe the next big visible evolution might happen here?
Thank you for sharing the Octopus Garden. Beautiful creatures! What deep sea mining is of interest? For which minerals or metals?
Thanks to you for sharing with us these incredible discoveries ❤
The research is impressive as a whole, but I loved learning about MBARI photo technology to document the Davidson Seamount & the underwater circle of life ❤
Great update. This is so awesome
Excellent footage and an interesting subject too.
I do have a question though, or at least a stumbling block - do the octopus mothers spend the whole of those two years guarding their clutch of eggs? It seems like that would be beyond extremely hard. I know it was shown that some die during the process (something I remember from BBC documentaries too), but given the abundance of shrimp, crabs, etc. shown in the footage, do the mothers occasionally have a meal in order to try to maintain some energy?
Female octopi cannot eat while brooding their eggs. It's their physiology. The Reef Doc on RUclips rescued a brooding female octopus some time ago and he explained what happens. He showed the hatching as well.
I do have the same question! Please somebody gives us light. 😊
@@Darkralos My understanding was that once they started brooding, they stopped eating.
They do not eat once they lay their eggs. Also, octopuses are solitary creatures, so they are entirely on their own when it comes to protecting their eggs. This is why they don’t eat. If they left to go hunt, their eggs would be consumed by someone in seconds, likely. So the stress and hunger generally does it for them (being unable to survive much past their babies’ hatching, if at all).
So the fact these ladies are grouped together is really interesting, and in my opinion, it also contributes to the faster length of time for the babies ro hatch! Since the solidarity keeps them from being able to eat, who knows, it might be possible that being grouped like this allows them to eat. Octopuses are so smart, so it wouldn’t surprise me if they found out that their eggs are safer if they group together like this, and that sneaking off to go hunt will be okay!
This seems like a much more effective process - to join forces like this… I would be very curious to learn if this is passed on to future generations. “It takes a village [to survive past the hatching of an octopus’s eggs]!”
It breaks my heart to see these moms give everything for their eggs, then their life.
His voice is so soothing
Glad you popped up on my feed! Beautiful!
The Beatles were the first to discover this…back in 1969!!
Yeah, i remember learning how octopuses die shortly after or right before their babies hatch. It is very stressful for them to lay their eggs and protect them from predators. What isn’t mentioned here is that one of the main reasons they die is because they pretty much don’t eat while they are protecting their eggs. Octopus are solitary creatures, so they don’t have the fathers or other octopus around to hunt, find or share food with them.
Because octopus are generally solitary creatures, it is quite amazing to see these octopus join each other like this! And I must say, I think there’s more to the eggs hatching more quickly than warmer water!!! I have no doubt that these lady octopi grouped together are helping speed up the process because they are less likely to be stressed out defending their eggs from predators. Who knows, maybe octopus have discovered that being amongst others eases stress, eliminates or lessens their hunger, or something else. Octupus are such intelligent creatures, and there is so much we are still learning about them, so who knows what else could be going on here that we don’t know about! Seriously, though… there is no doubt that animals have their own way of communicating… so I really wonder how this happened. They did not group together like this by accident!
Splatoon Reference
Octopuses have been observed by scuba divers challenging each other over a mound, as if playing King of the Mountain, and then at the end of the afternoon separating to their own holes. Like many mammals, whether they are solitary or join in groups seems to be a matter of food supply. Most of the places we easily observe octopuses, are also heavily fished.
Gorgeous site!
That’s amazing. We need more octopuses.
Outstanding research, truly incredible, great job!!
Thank you for sharing! Absolutely fascinating.
Thank you. It’s another amazing place.
Fantastic content !
That was truly beautiful and interesting. Thank you.
I am reliving the first discovery! ❤
A most beautiful world you presented. I cried with the magnificence and life bountiful water world WE all live in. Thank you.
Just amazing! Thanks for sharing how cool nature is!!
What amazing creatures
Amazing fotage! Thank you very much for sharing all the interesting informations which hopefully brings more awarnes and protection!
Great video guys
groundbreaking, truly
thanks for sharing.
The mysterious ocean… 💜
The Pearl octopus nursery garden is wonderful ❤
I wish the mothers did not die after incubating their only brood of children 😢🐙💔
This is so cool to see
So beautiful
Very interesting and refreshing ❤😎🔥
This is wonderful to see and so interesting .🐙❤
How far do the octopus travel to lay their eggs here ? Do they always lay eggs together? Is it just 1 breed of octopus that does this ?
A true delicacy in great sea food
That was just amazing 💙
非常有用的信息，谢谢
Amazing video
I’m curious if the increased temperatures make it harder for the octopuses because it increases their metabolism
See we are not the only ones that use hotsprings.
I hope Ringo Starr knows this exists 😊
Lots of delicious, umm... I mean beautiful creatures gathering in one place to catch them, I mean observe them 😂
Very cool
To think of all he hard work that these beautiful creatures go through just so the disgusting human animal can eat them.
Davidson seamount sounds cool.
I wish I could go but it's too much pressure.
Yea and if you did it might end up leaving you under water.
Sadly, this means all of them will die afterwards as octopus only lay eggs once in their life and then die of exhaustion.
I had no ideas it took that long for eggs to hatch 😮
A beautiful story to learn about! ❤💖🤗🥰👍😍🤗....those water plants beside them..were actually mouths on a stem! Haha....I noticed one chewing on something! 😅
My biggest phobia is the harvestman Spider 😱😖😩.....
The ones in the abyss are 99.9 % worse! 🥺😳🤯😵
It looks like "boiled octopus", one of the Japanese cuisines in that posture ...
Undoubtedly a stunning discovery. Octopuses congregating for spawning (laying?) eggs are unusual, contrary to their shallower water cousins, hiding into a small crevice to take care of the eggs. Mouth up posture (?) taken by most of them look like as if they were dying ... Their instinct for eggs till the end of life is shared. How did this behavior start?
We named it …blah blah… therefore it should forever be called the blah blah pus and we’re all going extinct. How interesting! Octopuses 🐙💖💖💖
Are you ok?
I hope we protect them and prevent people from farming or fishing these magnificent octopuses.
I hope the area is protected. 🙏🏽 I fear people hunting them now that the location is so specifically shared.
Deep sea tourist submersibles have recently seen a sharp fall in popularity.
8 years in a egg? Wow
I would be interested to find out what planet they originated from. I think 🤔
The deep see is the one place man kind hasn’t ruined yet
The animals are like we gonna have to go elsewhere these weird land creatures keep following us
2years? That’s super long for momma to sit there without food. Doesn’t seem right. That’s longer than anything I know of.
It Spring Break at the Hot Springs for Octopi
❤❤❤❤ octopuses 🐙🐙🐙 sephlopods are my favourite type of animals
2 years?
Yes ! What Do they eat down there...........
How long does this breed live ?
Wow
PROTECT THEM AT ALL COST
waiting for that Beatles reference... Oh wait somebody already got to it
For most of us this is incredible...but sadly enough there are a few who cant wait to sell those and wipe em out.
So many foods😋
Son animales increíbles y hay que protegerlos, sobretodo de los depredadores humanos 🤨
What's the difference between octopi and octopus -other than singular? I've read both terms in old books.
Octopi is plural, that's it.
@@mikeomolt4485 🧐✔️✔️
You really shouldn't have even told anyone.
👍👍👍
Octopie are smart anuf and with these vents causing them to congregate, I wouldn't be surprised if someday, certain octopie evolve to move and hunt in packs
I agree! They are normally solitary! I also wonder whether their biology could evolve to become social creatures that are actually happy and stimulated by the experience of being around others. Octopuses are so intelligent, and it surprises me that despite that intelligence, they normally isolate and keep to themselves, only. I think socialization can sometimes be a sign of intelligence…
these were my sentiments exactly
@@thenoises1604
Squid do now.
❤❤❤❤❤❤❤❤❤
Climate change is bringing us octopi gardens. I love it!
Now some energy company will lay claims on it and destroy it.
Takodachi!??
Hey, let's destroy that to mine rare minerals ! yeaaaaaahh !

Octo canyon is real???
Ringo starr and the beatles were the first to dive rhere😅it looks like theyre preparing for world invasion.
My objective? Work for MBARI
Deep sea mining hasto be one of the dumbest ideas of my lifetime.
I just love looking 👀 at God’s creations under the oceans 🌊
