The otherworldly creatures in the ocean's deepest depths - Lidia Lins 

This is why the ocean terrifies me, guarantee there's undiscovered nightmare creatures dwelling down there

Somewhere down there.....Spongebob missed a bus

It's odd that in these dark depths, the inhabitants still rely on vision to function. You'd think they'd use something else, like echolocation. But nope, they use their eyes.

Ted teaches me more in 5 minutes than my teachers do in an hour.

Thank you for using the metric system! :D

Go deep enough and you'll find spongebob.

Dear +TED-Ed. Normally, all your videos are a treat to watch and I always look forward to these lessons. But this lesson had another awesome feature that I wasn't expecting. *The sound!* Not only was the narration on point, the sound effects were chilling, like they should have been! Thanks again for the efforts you put in the videos.

just imagine if there where another intelligent species under water, and they think that there are more intelligent species under water, so they venture down there, while we do the same thing, just above and over water.

Just keep swimming.

You guys should have mentioned hydrothermal vents

And they say mermaids don't exist

and how many have we already wiped out without our knowing. :(

The giant squid is such a mystery, what do they eat that makes them so big?

Honestly this topic is so interesting. Especially from an angle of horror, I imagine it being terrifying to go into the depths of the ocean only to discover some of these giant species.

Once i heard a man say: "It must have been wonderful, but also scary, to live back in the old days, when you couldn't know what laid behind the next mountain". I showed him this, and he started bitching about how that wasn't what he ment.

deep sea is a big NOPE in my book.

95% of the unexplored depths are probably dominated by kaijus. I wouldn't go so deep.

What would happen if any of these animals living so down below would come to the surface or somewhere closer to surface water area? Would the lack of pressure affect them in any way? What about increased Oxygen into the water and sunlight? Will that confuse them or even kill them?

Ted videos are just perfect, they value the viewers time and still teach us a lot better than anybody could!

"we fear that which we do not understand" the deep sea is the one of the biggest mystery of this world we call "earth"

Oh, so that is that one terrifying fish from Finding Nemo! Nightmare fuel at its finest, ladies and gentlemen!

This is why I'm so scared of the Ocean.

And yet there is an absolutely abysmal lack of deep sea documentaries on Netflix. There are maybe two, one of which is just an episode of a series.

ugh i just love ted-ed videos so muchhhhhh

The animals in the deep ocean are not unworldly or unearthly, they have been there a long time. We have just now, within the last 100 years, started exploring the deep ocean. Some creatures may have been around longer than humans. I do have a question: When bring a creature up from the depths, would not its body , because of the pressure difference, start to expand and finally explode?

@ 1:10 - 1:30 You could say, that Edward Forbes’s theory “was blown out of the water.”

I always get a pleasant chill at the end of all videos, because the endings are so inspiring and powerful

Beautiful illustrations! Very informational and interesting. I'm glad I was assigned this video to watch. :)

This was really well made! Awesome work

But what about... a Sea Bear?

The ocean is just amazing. I'd love to study marine biology someday.

Great video, really enjoy the latest educational videos. However I would ask you to please add captions to your videos as it greatly increases the availability and we can share them to more people. Thank you and keep up the good work.

The ocean is so scary idk what’s down there and it makes me feel so uncomfortable

I hope we can use bioluminescence technology to remedy my country's problem in electricity

I always wondered if there really is "no light" at the bottom of the ocean. Reason being, Amblyopsidae are a type of fish found in caves where all sunlight is blocked off so they don't have any eyes at all, yet fish and other animals at the bottom of the ocean do. So if we know that the cave fish don't have any physical eyes because no sunlight at all goes into the cave, why do fish at the bottom of the ocean have eyes? My theory is that they CAN see, their eyes can see more of the light spectrum than we can so while we see complete darkness they can see everything. If anyone knows of any official theories like this please let me know because I'd love to research this.

if a giant fish dies underwater, will the remain float or drown?

thanks for the metric system.

This was so awesome and interesting.:D

Thank's for your persian subtitles. Really appereciated.

Love this channel 😍 Love from Darjeeling, India 🙏🏻

No mention of volcanic vents and their contributions to the ecosystem?

I much prefer this woman narrator.

I just cant stop watching these shortfilms

İ once came across a documantery. İt was the best documantery i ever seen in my life. İt was about deep oceon and i only seen the near of end, but even with this it was incredible. İ couldn't find it again. İt was like an oasis in TV. Sad i can't find it 😟

What if Earth is just a small particle at the deepest depths of the ocean which is why the universe is mostly absent of light, except for stars and other such things?

this is why I wanna be a marine biologist

Land animals: How do you guys even survive there? Deep sea creatures: *How did they get legs?*

thanks TED-ed!

dont explore too much, you might discover the atlanteans and wage war against them XD

I am scared of deep water Even seeing pictures of deep water darkness terrifies me...

Learnt a lot. Thanks

this is amazing.

4:28 Hey look a Reaper Leviathan!

What if scientist explore the ocean rather than exploring space. I mean space can give us more info about life, matters etc. But what if the life under the ocean can give us more info to a i dont know maybe alien life, fossils, or matters that we dont know. We are so excited about discovering something specially above rather than under think about the stuff we can use if scientist first discover the ocean. My point is we can explore what we have here on our planet theres still so many mysteries hiding and waiting for us to see.

My sister said she would outsmart me, but I have THE POWER OF TED-ED!!!!!!!!!!

I enjoy listening to these while drawing its nice and relaxing

"Under the sea, Under the sea, Darling it's better, down where it's wetter, take it from me...."

I have a question: why do underwater creatures get scarier as we go deeper?

That's so interesting!

Oh , God!! So fabulous!!

2:22 that theory of camouflage make not much sense to me, what if the predator is above or at the same level than him? It would attract predators. In a dark place, I think not shining would be the best camouflage, light would just make him more visible

its weird that i saw some pineapple-like coral deep in the pacific ocean...i wonder what is it?

The thing is that because humas dont go that deep , that has to mean the deep ocean is the cleanest place on Earth. That is just depresing.

How ironic we reached the billions of miles away into the space but haven’t yet fully explored 7 miles deep underneath the ocean.

umm am i the only one terrified by oceans, rivers and lakes? like, the water is dark and you can't see what's under you and there are all these scary-ass fish and snakes and crocodiles and sea-monsters... i've never been swimming in a lake or river and i never will.

There's some fucked up shit down there

thanks, with these videos i am practice my english

When I think of the creatures we have yet to discover in the deep sea, I imagine seeing the ancient Tatanaboa, though changed through the many years (perhaps even larger)

I had to comment 'cause the title is in iambic heptameter.

What is under the ocean? 99% Pokemons!

I ❤️ this channel so much

The deep sea is so fascinating. I wouldn't mind dying if it meant I die in the middle of discovering a beautiful view.

The moment humans reach bottom of the ocean is the moment where more species will go extinct...

If about you but I can't wait to meet JarJar Binks in our own oceans b4 meeting Anakin or Obi-Wan

Super!!! Congratulations! 😀

thank you ted.

WHAT IF THERE ARE ANIMALS IN THE MANTLE OR LAVA :v

3:27 I'll just tell the girls I date I didn't eat too well that day! Lol

This planet is such a treasure.

Just imagine exploring it and seeing these animals at closer angle

cthulu. that is all

- _- The sea...

Really cool!

There is also chemosynthesis in which organisms can produce food without needing sunlight. Many deep sea creatures rely on chemosynthetic organisms along with hydrothermal vents (which provide minerals and nutrients) to feed on. I'm not sure if they mentioned that in the video, but I found that fascinating when I learned it:3

0:58 wouldn’t the water freeze

Hola

I'm In LOVE With The Word MYSTERY

Sea creatures are so fascinating! :)

we discovered %5 of the ocean but polluted more than 10% of it.

i feel as though the production quality is dropping

This is why I'm studying Marine Biology. The Bathypelagic and Abyssopelagic zones are probably the coolest, most mysterious regions on the planet

Scary thought to be swimming on the surface of the deep ocean knowing that it goes that far down and what dark creatures are below you.

THIS IS WHY I'M AFRAID OF DEEP, OPEN WATER!!!!!! -DEEP OPEN WATER- *no thank you* i'll pass that up

spider krabs? there is no god

Good morning, Marata here!!! Thank you for sharing madam.

you guys r great i love all of ur video

one word. mermaids.

Marvellous ma sha Allah ♥ ^_^

0:15 Wow, such a technical and obscure word

I loved it :)
