About 60 percent of the ocean is a cold, dark region that spans down to 11,000 meters. This zone is known as the deep ocean, and though it seems like an inhospitable and remote corner of the planet, it is actually one of the greatest habitats on Earth. Lidia Lins explores how so many species thrive in this mysterious underwater world.
Lesson by Lidia Lins, animation by Viviane Leezer.
Somewhere down there.....Spongebob missed a bus
ha
Rock Bottom
My child watches that show all the time
LMAO
Get this man a medal
This is why the ocean terrifies me, guarantee there's undiscovered nightmare creatures dwelling down there
Like Tai Lopez?
Retro pigynator Ohhh.
cookie cutter shark
+brutal turtle (brutal turtle) please no
+Charles Ferreras my name is brutal turtle
Go deep enough and you'll find spongebob.
And Patrick, they're probably wearing seaweed mustaches singing about they're newfound manliness to get past all the monsters.
***** Squidward tennis balls!
hi nathan
+Boba Vhett Squidward Tortellini xD
bikini botom is too deep for most men
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.
The ones with echolocation hide any time one of our marine machines gets close ;)
Now thats spooky aint it.
Their eyes are very small. They usually use other senses like that one along their lateral lines that helps them detect changes in water currents. I think
EnderStar501
The Colossal Squid has one of the largest eyes in the animal kingdom. Also consider that most escape (Vampire Squid) and prey attracting (Angler) methods are entirely dependent on the prey's dependence on sight. Then again, not enough is known about abyssal creatures to know if they rely on lateral lines or alternative senses like electroreception.
John Doe Rly? oh wow
Thank you for using the metric system! :D
yay someone else care .. ♡
+Pastel most these video's are made in US, seeing use metric system is really a rarity for the rest of us
Procker Dark I feel u
Yeah... even though I didn't grow up with it, the metric system just makes so much more sense! At least, for some things.

Ted teaches me more in 5 minutes than my teachers do in an hour.
Lol
The Chaotic Artist same sometimes we go to the imc/LikeACinema and watch vids sometimes movies like inside out its all cold and i love cold xD (Not To Brag)
Ikr
The Chaotic Artist but how much of it are you going to remember
The Chaotic Artist ur teacher suc
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 keep swimming.
Caleb N just keep swimming just keep swimming.

Damaged lips just keep swimming
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.
They probably live in a city called Rapture!
thats what i think at times. i mean didn't life first start in the water? so whose to say there isn't another type of humanoid species that started down there as well. especially when you consider the head start they had with evolution. unless i just sound like an idiot... lol but it would be amazing tho.
I don't think they would look anything like humans if darwins theory is correct
I think regardless, they wouldn't evolve much as there are less evolutionary stress and not much energy source available. Also, not being able to see much around you doesn't provoke much curiosity.
Gary Oak
"And they think that there are more intelligent species under water...."
Meaning that they are exploring feather down....
The giant squid is such a mystery, what do they eat that makes them so big?
Whales mostly
Anything they get their tantacles around. Theyre scavenger predators. Survivors highly intelligent they dont really hVe a set diet of any kind, increasing their likelihood of receiving a meal.
Fish. Substantial amount of fish.
Star Cherry Deep sea gigantism i guess?
Other deep sea creatures.
You guys should have mentioned hydrothermal vents
Yeah, they probably should have mentioned chemosynthesis
They really should've.
I think given the scope of this video they did pretty good because honestly chemosynthesis in the ocean floor vent biomes deserves an entire video of its own. Especially since we think those environments might simulate the early earth and the archaea there might resemble the earliest pre-oxygen era creatures.
why
Because they feed deepwater ecosystems entirely devoid of sunlight. No marine snow, no photosynthesis, nothing but the mineral vents from the Earth's core! There is also the brine seas that are essentially water to the ocean's air, and cover vast areas of the sea floor (and also host ecosystems devoid of sunlight).
and how many have we already wiped out without our knowing. :(
:(
I think that there aren't much at all, since they're probably too separated from the surface
Christopher Lie increased ocean acidity could be a factor, as well as changes in the ecosystems of fish that lives in the surface. We all know ecosystems are linked, if you mess up one part the whole system might not be able to fix itself and become a disaster
+pramitbanerjee Oh, right. Didn't think about that. But I'm still unsure if this has caused much extinction for the creatures living in the deep ocean.
Christopher Lie well, you have evidence of this happening at the surface level. Its always better to assume the worst and prepare accordingly.
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.
And they say mermaids don't exist
If they exist in such depths, I'm willing to bet my life savings on them not being hot chicks with fish tails lol
you can't say that for sure.
if they're not hot chicks there's no point believing in them or even caring about them
***** exactly. maybe they wont be really hot chicks who lure sailors into death, but ifbthy leave at the bottom of the deep sea and are horrendous creatures wih some mermai features (the tail and the humanoid characteristics) then its possible than they exist. we cant be sure, we dont know 95% of the ocean. so no. you cant say for sure *****
+Maria Hakobyan dont even start with the conspiracies
deep sea is a big NOPE in my book.
It's a yes
it's a yes in my book, im going to the bottom of the trench and digging
Nati Whatever the entire ocean is a big NOPE
Next Stop: The Abyss
It’s a Yes in every book I own! Anyone agree?
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?
U know the blob fish? Every picture u have seen of one is dead
Could you explain? Is that the "
The lack of pressure will transform some molecules in the animal from the liquid in the gaseous phase" part?
Oh wait, Blob fish! I thought you were talking about the Balloon fish. My bad. Well, I'd assume they're dead cause they look that way. But is there any transformation that their bodies overwent after they got surfaced or that's the same way they looked when they were on the bottom of the ocean? Cause otherwise you haven't really answered much of my question.
Carl von Herrlichingen Also, Carl, thank you for your explanation! It's true what you said in that last part. The lady in the video is saying that Jellyfish can migrate back and forth (or should I say above and bellow) due to the fact that they're made out of 90+% water so they can withstand huge amounts of pressure. Idk about these molecules you were talking about though but it might be true.
Ok so basically when molecules are under immense pressures such as those found in the deep ocean things which would normally expand out and become gases are confined in the liquid state as the pressure from all around does not permit their molecules to move sufficiently far apart. When you remove this pressure the organism's tissues would expand drastically as they are no longer being pushed inwards by the huge water outside their body.
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.
I dont get what you meant :|
I think what he's saying is, the guy wanted to be in a time where the frontier was full of mystery and your imagination could run wild, but when people actually explore it and information about what it's like becomes available, it starts to lose some of that magical quality.
imlaughing2death oh yeah like after an anime plot twist or biggest secret was revealed
he just didnt want to go back this far in time lol
Ted videos are just perfect, they value the viewers time and still teach us a lot better than anybody could!
95% of the unexplored depths are probably dominated by kaijus. I wouldn't go so deep.
whats that
like godzilla and friends
Even if we did, they couldn't come on land since they would be too heavy to survive without water support. Whether this is a good thing or a bad thing, I'll leave for you to decide.
Jeyna LSC I hope so! With 21st century materials, we need to get some new subs down there.
Jeyna LSC hmm...*summons Godzilla from the deep*
ugh i just love ted-ed videos so muchhhhhh
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.
Heh. Abysmal.
On a serious note, perhaps a lack of such documentaries is because these deep-sea expeditions require a lot of funding for proper working equipment. And even after that, the animals might get stressed from the artificial lighting (unless you're using those night vision device). In fact, the very presence of the camera, if noticed, might trigger stress to the organism, defeating the purpose of observing them in their natural environment.
tl;dr, it's a high-risk-high-reward thing, and not many people are willing to take that chance.
Also I just realized you said deep sea documentaries in general, so I apologize if I went way off the tangent here.
"we fear that which we do not understand"
the deep sea is the one of the biggest mystery of this world we call "earth"
This is why I'm so scared of the Ocean.
look up cookie cutter shark
look up the dumbo octopus (discovered in 2015)
+YoAddicts oh god no
+YoAddicts I did a report of grimpotheuthis last year
And I struggle to get over angler fish.
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?
Thank you i was not sure about it
Plus deep sea fishes and animals adapt to the pressure levels by having bodies made out of jelly and they have much smaller bone structures. The deeper you go the more jelly you get :D
+Lorie Franceschi blob fish are good examples of the effect of pressure
1 animal though, the giant siphonophore, will burst if it goes too high. They live in very deep waters and are super long. If a giant siphonophore goes too high it will get bigger, and bigger, and bigger, until it will burst.
By the way, regarding animals being around longer than us, look up jonathon the tortoise.
Oh, so that is that one terrifying fish from Finding Nemo!
Nightmare fuel at its finest, ladies and gentlemen!
i can draw a more terrifying version
+Khorps who the fuck cares
Reptile estrin i do
I thought that was a barracuda
the barracuda is in the beginning and the angler fish is in the "just keep swimming" part Krezzer is talking about
@ 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
The ocean is just amazing. I'd love to study marine biology someday.
This was really well made!
Awesome work
thanks for the metric system.
My sister said she would outsmart me, but I have THE POWER OF TED-ED!!!!!!!!!!
Beautiful illustrations! Very informational and interesting. I'm glad I was assigned this video to watch. :)
But what about... a Sea Bear?
The ocean is so scary idk what’s down there and it makes me feel so uncomfortable
I just cant stop watching these shortfilms
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.
This was so awesome and interesting.:D
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.
+Bob yes
Maybe because caves didn't have friendly bioluminescent bacteria for fish to absorb? I know so little though.
Revi M Fadli I feel like even then the ocean doesn't have enough natural light (other than the sun) for fish in the bottom of the ocean to keep their eyes after all these years, but it does sound like a plausible explanation
Thank's for your persian subtitles. Really appereciated.
สุขภาพแข็งแรงค่ะ
if a giant fish dies underwater, will the remain float or drown?
Other creatures would have finish it down to its bone before you knew it.
It will drown to the bottom very bottom of the deep ocean,for example if a whale dies it will drown and it will be a food source for animals like spider crabs,some sharks,other marine animals that are at the deep bottom.
Fish drowning
You mean sink genius
I believe it's kind of like a blackhole, after you reach past a deep ocean's horizon point everything just begins to sink due to atmospheric pressure.
No mention of volcanic vents and their contributions to the ecosystem?
Which is strange considering they are like the oasis of the deep. Where life flourishes and they play a vital part of their ecosystem.
make your own video on it
Chemical soup from when it was raining rocks earlier.
Learnt a lot. Thanks
I'm In LOVE With The Word MYSTERY
this is why I wanna be a marine biologist
I know this is late, but good luck chasing your dream!
I hope we can use bioluminescence technology to remedy my country's problem in electricity
Idiot
Bioluminescence is being researched as a possible substitute for street lights among other things, so why is he an idiot?
+Lime Icing it still requires energy to produce the light I guess? Idk, it's probably because this is a YT comment section 😂
ladylililala
Yes, but the bioluminescent organism usually uses naturally provided energy, as opposed to street lamps of today, which (mostly) uses energy provided through a power cable.
You're probably right about it being the YT comment section, though :P It's pretty horrendous
Bioluminescence is produced through chemicals, rather than an electrical current.
this is amazing.
Love this channel 😍 Love from Darjeeling, India 🙏🏻
I much prefer this woman narrator.
I know right? The guy's voice pisses me off I can never finish a video
+Clément Guardiola both are good in their own ways I suppose :)
Both are amazing! The male narrator's voice is so crisp and beautiful!
feminazi fuck off
+Donald Trump dear sexist republican sir, do everyone a fucking favor and fuck off
dont explore too much, you might discover the atlanteans and wage war against them XD
unli distraction Ikr
Aquaman in a nutshell
AYEEE YOUR PROFILE PHOTO IS CONNORRR
thanks TED-ed!
I ❤️ this channel so much
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?
thats deep. get it, deep.
+Baumworld Clap. Clap. Clap
Well, considering the "bubble universe" theory that would make sense, but it would be an ocean of infinite universes or multiverses.
Horton
This concept really blow my mind.
I am scared of deep water
Even seeing pictures of deep water darkness terrifies me...
Oh , God!! So fabulous!!
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 😟
"Under the sea,
Under the sea,
Darling it's better, down where it's wetter, take it from me...."
4:28 Hey look a Reaper Leviathan!
I enjoy listening to these while drawing its nice and relaxing
That's so interesting!
I have a question: why do underwater creatures get scarier as we go deeper?
because they live in a habitat more and more alien to our environment. Creatures that live in different environments will look different(penguins in the south pole vs lizards in a desert ECT).
Deep ocean creatures live in such a foreign and alien environment to us that they are foreign themselves.
No one can critique your looks if they can't see you
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.
This planet is such a treasure.
0:15 Wow, such a technical and obscure word
its weird that i saw some pineapple-like coral deep in the pacific ocean...i wonder what is it?
MR. Derpy OOOOOOOH
WHO LIVES IN A PINEAPPLE UNDER THE SEA!
SPONGEBOB SQUAREPANTS!!!!
As yellow and porous and absorbent as he?
There's some fucked up shit down there
thank you ted.
Good morning, Marata here!!! Thank you for sharing madam.
I had to comment 'cause the title is in iambic heptameter.
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
Abdulkarim Elnaas
Yeah I know they can use their other senses instead of sight, but when we are talking about camouflage we are talking precisely about hiding from their sight. And using light would do exactly the opposite
Maybe their predators don't see light? But their prey do (which is why the luring technique works on them)? Or maybe they just don't see certain colors.
burt591 these creatures are light only on the bottom, but are dark on the top so life from above just sees the dark ocean
The hunter can't detect its shape as was stated in the video
You don't wanna eat an invisible glowing thing right?
Really cool!
thanks, with these videos i am practice my english
The moment humans reach bottom of the ocean is the moment where more species will go extinct...
I kinda agree
Damn you're right.
Pre-human rates of extinction were about 1 species out of the 10 million a year. Currently the rate of extinctions is about 1000x the pre-human rate. And no, it is not a coincidence, it is our doing. If you disagree please supply examples of your points and proof as well instead of telling my family line to go extinct. My source was this - news.uga.edu/releases/article/species-extinct-1000-times-faster-than-pre-human-times-0914/
Not really,it's not like we'll be able to survive down there until after 200+ years from now
+Jon Mike Holy shit I don't think the ocean is needed for salt anymore.
cthulu. that is all
Alex MacGregor
i think kraken is better
And kaijus.
Spongebob
Super!!!
Congratulations! 😀
Sea creatures are so fascinating! :)
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.
Try Green Lake, Austria! The water is crystal-clear. That's because it is a snowmelt lake that only forms in May-June. Because it is just the right temperature and so clear, all the plants and grass and stuff that it submerges stay alive, despite being underwater. You can see more here: en.wikipedia.org/wiki/Gr%C3%BCner_See_(Styria)
SnowLeopard84 fangirl thanks, it's really beautiful. it didn't change my mind tho, still terrified
Awww! I'm afraid of heights. XD But I've been trying to conquer that fear and it has been paying off. Maybe you can too with your fear of murky water! If you can't... well, I wish you luck in find other beauties of Earth to explore!
i don't know, i don't really have the desire to explore lakes and rivers. i've been snorkeling with sea turtles tho. i also lived on the 10th floor ever since i was little, so i actually love heights
Cool!
0:58 wouldn’t the water freeze
right? good point
The ocean is amazing
you guys r great i love all of ur video
Hola
hola, :-)
Holla Holla We Dem Boyzz!..
Sorry
What is under the ocean? 99% Pokemons!
How ironic we reached the billions of miles away into the space but haven’t yet fully explored 7 miles deep underneath the ocean.
I loved it :)
WHAT IF THERE ARE ANIMALS IN THE MANTLE OR LAVA :v
Microorganisms probably
+Pixel Master Exactly
Yeah or maybe there are animals in the fucking vacuum of space
+Reptile estrin hopefully
there is a extremophile that can survive in space, if it has a food source
spider krabs?
there is no god
You CAN eat them, however. Well, the large ones, at least.
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.
Just imagine exploring it and seeing these animals at closer angle
If about you but I can't wait to meet JarJar Binks in our own oceans b4 meeting Anakin or Obi-Wan
one word. mermaids.
No.
Even if there were mermaids in the depths, they would be adapted to high pressure and so when brought to the surface they would become bloated and hideously deformed and overall not very pretty
this is even more useful than online class.
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 sea...
3:27 I'll just tell the girls I date I didn't eat too well that day! Lol
This is why I'm studying Marine Biology. The Bathypelagic and Abyssopelagic zones are probably the coolest, most mysterious regions on the planet
Good for you!
I respect the contents of the Ocean 🌊🥶🙏🏽
i feel as though the production quality is dropping
Yeah some really rigid animations in this one
THIS IS WHY I'M AFRAID OF DEEP, OPEN WATER!!!!!!
-DEEP OPEN WATER- *no thank you* i'll pass that up
The music is great
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.
