The Most Shocking Creatures at the Bottom of the Ocean 

Imagine being in a submarine far into the ocean, you land and the floor bleeds. Sounds like something comming from a eldritch horror novel

Isopods say "I know a place" and take you to a deepstaria jellyfish.

Micheal has a new hairstyle every video yet Hank hasn’t changed in 5 years. Both look great!

Y’all should do a compilation of studies that have changed (like things we didn’t know and now do, etc..)since you’ve made a video on the changing subjects.

Funny story about the Alvin sub. I was so scared of getting a new job that I decided to talk to a therapist to help me through the process (job security issues/constant rejction in the past). At my first appointment, he had a shirt on that had a small picture of it. Being a scuba diver, myself, I was curious and asked him about it. Turned out he was part of the crew of the Alvin sub. :)

Aranda is slowly transforming into the green power ranger, when he had that late 80s early 90s mullet going on.

I remember the video from Nautilus Live when they found that Deepstaria. It was such a great moment, listening to professional scientists geek out like college kids. And the animal itself was just plain gorgeous, mysterious, and fascinating.

SciShow: For over a century, their habit of fatally overeating was the main way scientists collected specimens Me: noice

The swept back is a good look on you Michael, rock on.

What we learned recently: In order to study the deep sea species you have to go there and take samples in highly pressurised receptacles. A LOT of planning and work involved. We actually never really thought about this before. So we followed the scientists along on their quest to the depths of the ocean. That was very insightful and great fun indeed.

"Who knew a giant mouthless buttless worm would redefine what we know about how life works on our planet". I agree my friend. And how weird is it that that worm makes blood plumes? Boom 🤯

Who the hell ate 70 hot dogs without vomiting???

The big mystery: why is he wearing a jacket?

The entire bacteria - tube worm symbiotic relationship is super cool and actually might be a good way of understanding how more evolved animals initially developed mitochondria millions of years ago.

in a few billion years or so those tube worms could go the same route as the ancestors of plants where the photo/chemosynthetic bacteria fuse with their respective hosts.

3:22 Aw man. I had a really good joke prepared about what the worms were full of if they can’t poop

Hair looks awesome, Michael! I’m beginning to get jealous. Lol

"Why is it like this?!?!" pretty much sums up studies of deep sea creatures imho

"... four times as long as the swallower" lord hammercy!

Hank, I'm a really big admirer of ur childish enthusiasm when u r explaining stuff. Keeps me hooked.

Awww. That drawing of the dragon fish was adorable

This channel is the only sleep medicine that works for me

1:54 I wonder how the researchers first reacted to that, honestly.

I love when you guys make videos like this ,the other more sciencey videos I find hard to follow since I'm not a science guy but I'm a animal lover to the core ,much Love from Compton california

I didn’t know baby Steven Seagal got hired to do sci-show now.

Dude, your hair looks awesome tied back! I'm currently growing mine out to do a similar style, as well

Giant _Anuropus_ Isopod: (encounters _Deepstaria_ Jellyfish) Also Giant _Anuropus_ Isopod: *_IT'S FREE REAL ESTATE_*

He never mentioned how big the giant tube worms got.. so i googled it.. they grow up to 8 feet.. over 2 meters.. now thats a GIANT tube worm!!🤯

Michael has joined Los Lobos. It's official!

subnautica is a masterpiece, if anyone would like a deepsea simulator.

I love everyone being nice about Michael's hair! So nice of you guys to show restraint :)

why am i so proud of your ponytail xD

I miss Olivia 💜

I'm not sure why, but hanks delivery with his jokes kill me everytime! I'm not happy they make me laugh. But they make me laugh. XD

I start to think life only really needs two things to happen: Lots of possible elements to work with (especially highly active elements and compounds) and a place that has a (mild) energy flow of some sort (e.g. heat).

"a giant mouthless, buttless worm" = description of the century LMAO

Imagine how many fossils of unknown prehistoric species are buried at the bottom of the ocean that we’ll never be able to get to.

Interesting point, the truly gigantic Stygiomedusa Gigantea has a little friend of its own. On the rare occasion we spot one(only 110 or so have been in the century or so since we discovered them!) They always have an Itty bitty fish called Thalassobathia Pelagica. I recall it being mentioned said fishy isn't found anywhere else(could be wrong on that and sadly no time to research 😢) its usually seen right up underneath the bell. I find it intriguing how incredibly different from most jellies they are. Almost like they are more evolved. I suspect the relationship is the jellies offer a safe place to live and the fish rids them of parasites. Its a bit vexing that despite having observed these deep sea behemoths(deepstaria, Stygiomedusa and big red...Tiburon?) We've never really examined one it the lab. That must be epically aggravating to biologists. I recall the lady who invented the splat screen and jelly fish lure and pioneered research into bioluminescence. She also had a big hand in figuring out how to attract an arcateuthis dux. During a submersible dive with the Monterey Bay folks she had the incredible luck to run into(almost literally!) A Stygiomedusa Gigantea. It was so close they couldn't use thrusters and was only a few feet away from her. She very well may be the only biologist to ever come so close. They observed and photographed for a good bit of time. Yet how frustrating that there is simply no way to capture one(well trawlers occasionally get one but that really tells nothing as they are pretty much nothing but a mangled ball of snot afterwards and can be hard to tell if it was even a jelly or if a whale sneezed...hmm can whales sneeze!? I digress, as far as hands on examination such creatures might as well be on the dark side of the moon!

the deep ocean is fascinating, i doubt we'll uncover all its mysteries

I think I'm going to like this guy's channel. I'm going to learn a ton on this channel. And the sources are extremely interesting and ear catching. Good stuff.

Hank says symbiosis between tubeworms and bacteria could be thought of as "basically...an infection", but I'd like to think of it more like the bacteria have entered into a "pre/new construction agreement" before the rest of the (tubeworm) condos have been finished!

I was making dinner, I came in on the black swallower segment. This was an interesting one.

Maybe the isopod stays inside of a jellyfish to break down the waste of food after it eats, kind of like a garbage disposal

biologists: we believe some things are impossible for a living creatures bacteria: change your beliefs

Michael looks like a Jedi master with that hairstyle, and I love it!

The Deepstaria could benefit from the isopod in that other animals could try to eat it, only to be caught by the jellyfish

Thanks i knew about Michael Hill! He was my professor in Oxford and told us about FBC13 algorithm!

Funny enough, "Giant, mouthless, buttless worm" just so happened to be my nickname in highschool...

They’re all terrifying

I've caught heaps of fish with isopods in their mouths so I'm not surprised about the one in the jelly fish

Nice talk

I love these compilations

Here’s my idea for why they have this relationship. The isopod helps break down the food for the jellyfish and in turn, isopod gets shelter and food

The black swallower inflating and floating up made me laugh

I had an idea: what if the isopod lives inside the jellyfish to help attract prey for the jelly - predators of the isopod would smell(?) or sense the isopod and run into the jelly on accident. The jelly benefits by having something to attract prey and the isopod enjoys scraps of food inside the jellys digestive system. thoughts?

love this look michael !

The Black Swallower has nothing on Tarrare.

'Life will find a way', how true.

Micheal if you added an eye patch you'd look just like Snake Pliskin these days. Another great video from you and the team. Thank you for continuing to make these during these crazy, trying times.

Very cool information. Nice delivery and great content. Thank you. 💜😊

These are amazing

The bacteria making food for the tube worms kinda reminds me of how the first mitochondria viruses got trapped in cells and started making ATP.

Manbun comin'? Love it!

How'd they get Kit Harrington on SciShow?

Since the straw has no holes, as it is a tube, does that mean that worms are technically without holes as well?

1:11 it looks like its being lit by a 90s stage lighting setup/show that's been recently upscaled to HD I don't know what made me think of that but it was my immediate thought

His hair is getting so long and it looks so good

I've never related to another animal so much in my life

The more we learn about deep ocean life, the more "extinction event" only applies to most and not all life on Earth.

my questions is why the jellyfish aren't spotted with more than one isopod inside.

Come on SciShow the snake was a Ball Python . Wrong pattern and Boas don't have heat pits.

I love that isopod already and its the first time iv seen it

I am LOVING Michaels long hair

i clicked on this video expecting spooky fish and parallel-universe john green and im suddenly greeted with one of the most gorgeous human beings ive ever seen????? help????????????

6:45 sure someone pointed this out by now... but that's a ball python. Not a boa.

If isopodes are more advanced life forms then aren't the jelly fish the pets

Fantastic

Wow that latest subnautica update looks more realistic than ever!!

So basically ALVIN squished a whole bunch of worms and that’s how they discovered them 🪱

Hank's videos are the best.

The jelly with a hitchhiker inside, I'd also wonder why there is only one per jelly, if there is only one per jelly.

Loving the hair!!!

That jelly is trying to show you its friend :)

My dad helped them and the long Beach aquarium and the Cabrillo aquarium build the tanks they have everything in. At least 20 or so years ago haha

"Shut your mouth, butthole!" Tubeworm: I'm so confused...

Me: now how do they know those worm things are animals and not plants? Hank: ….plumes of red blood… Me: ah. That way.

Just a quick theory but could deepstaria and the isopod have a food based relationship? Perhaps the jelly is coated in a film the isopod finds appealing, whilst perhaps the isopods waste can be filtered by the host? Essentially recycling nutrition between the two in times when food is scarce? Anyways, great vid sci-show!

the hair \m/ lovin it

"Endosymbiotic"......think I may have found a new favorite word...

*Mitochondria are the powerhouse of the cell*

13:13 New band name, or Dethklok song lol

Omg! I'm loving the hair!

I refuse to make a joke! You know exactly about what

Nice video! What about FBC13 algorithm review?

I keep coming back to see Michael's hair progress!

That jellyfish kind of looks like a lantern; in the first pic you showed at least.

Pink pillbug, how cute!

"Evolving in a dark, cold, high-pressure environment like the deep sea will do some bizzare things to your biology." Bars?!

Really? 5 ads? RU-vid making their $$$

Oh I LOVE the hair
