the famous Attenborough catchphrase: “others are not so lucky..”
It’s forgivable because it’s only a clip, but the clip fails to mention that the brine pools are very hot, highly concentrated collections of methane, sulfuric acid and anoxia. Due to the high salinity, about 4-5x greater than the surrounding sea, an animal’s cells quickly lose water from osmosis, causing osmotic stress. Some animals, including those seep mussels surrounding the pool, have a symbiotic relationship with bacteria that oxidizes sulfides and methane. Animals like the eels are attracted to the food supply, and are subsequently killed for any carelessness.
Anoxia is a condition or state, not a compound. The term you're looking for is anoxic water.
I want to start my master’s degree :/ taking a break from college due to obvious reasons. So I’m here watching nature docs and reading.
Wow you explained more than the video did 😊 thank you !
Thank you for the info. One cannot expect from BBC to give all the info.. I was confused about that clip but your info helped me a lot. Thanks
The shot with the submarines lights behind that thing is incredible. It reminds me of an alien movie.
That one eel who didn’t even give a crap and just passed by 😂
😄
Homeslice needs a cardboard sign: "Homeless Vet. Please help. God bless."
It's a cruel world. But the reality is, even if they were capable of helping the other, that would only cause that eel to become more brazen and careless because it would probably figure another eel would just help it out. They figured this out by drowning mice. Let a mouse nearly drown but save it last second and put it back in the water and it will have hope you'll save it again. It was a disturbing experiment, to say the least.
@@Ana.401😂😂😂😂 y la tierra es plana? No me digas!
Its like a horror scene from another planet. Fantastic programming
Like the game subnautica
@@derk3933 Creation is so wonderful that more than 95% of all the species that have stepped their "foot" on this planet have disappeared.
1:17 “Somebody should probably help that guy or something”
It’s like what spongebob almost drowned in. Man and people thought lakes in spongebob were fake
Gas maybe? idk
The creator of spongebob confirmed that the island you see in the opening credits is based of the real life bikini atol, where in the 1940s several nuclear tests were carried out. So every weird thing in spongebob like fire under the sea can be explained by radiation
The creator of spongebob has a degree in marine biology.
no one thought that, even if you didn't know about the brine pool the cartoon can just say it's goo or oil.
the guy that created sponge bob was a marine biologist so everything had a degree of reality
These lakes are also anoxic. Meaning fish would indeed drown in addition to other ways they would die.
What happened to Mike DeGruy???? His death is still mystery
I announce officially my independence from swimming after watching this video
1:17 godamit, Carl
Not enough people get this!
Plot twist, carl’s dead due to toxic shock and that’s his spirit
Eerie as it is...the whisper of attenborough together with the ghostly sound made it more otherwordly
I Think its all about osmosis. there is a high concentration of salt to water in the brine, therefore it is more dense than normal sea water and that is why it sinks.
Fish, such as the eels, need a stable amount of water (isotonic) in and out of the body. since there is a high water potential (more water) in the eels than the brine (more salt to water) water moves from a high water potential to low water potential.
this leaves the eels with less water stability in the body, which is why they suffer toxic shocks because water is leaving the body and osmosis is passive (doesn't require energy) and so water moves dangerously out of the eels' naturally.I am currently doing A-Level Biology
But then what about the "toxic" shock. I think the toxic shock could be due to diffusion. Since your explanation also fits in perfectly, both the processes are occuring. But I guess the reason for the electric shock is diffusion of highly concenrtated salt solutions.
+Bo666y toxic shock Is not electric shock...it's bcoz of accumulation of toxins in body...
I doubt that the outer membrane of the eel could allow for osmosis. I think its got to do with the breathing of the brine water (through the gills) that brings in the toxic shock.
nice copy paste
This is sodium intoxication
I remember them touching on this in the first series, this is absolutely incredible. Easily the most incredible documentary I have ever seen. On nearly any topic.
Better visual horror than prometheus and the newest alien movie
I am utterly fascinated by this concept for some reason
WE NEED TO KNOW WHATS IN THERE
This is the closest the BBC or David Attenborough got to creepypasta. Love the dark ambient!
Tag your it..lol 😅 much love Sexy Grandma Darkness ✌💙💙
Holy shit, can't wait!!
If I ever have a heavy metal band, I’m calling it Brine Pool of Death.
I bet you all, if we don't take care of our water's pH, we're gonna have Revelations level of Calamity here.
1:18 the eel passed by on purpose just to flex like “Hey look at me, I’m not an idiot like this dumbass who went into the brine pool”
Ah...goo lagoon.
Should have waited after eating before going in
*BUTT CRAMPS!*
Is this what spongebob almost drowned in
Nature is soooooooo weird and awesome!!!!
Its like water under water
Scavengers, scavengers barely even human!
Hhhh it went on 3 times....eel's gonna learn today 👀
What a terrifying thing to see.
I was just looking at the thing from octonauts lol
Can anyone tell me what was the name of the eel? I'm making an article about the oceans, and I didn't hear it right
Cutthroat eel.
This stressed me out & I'm not even the 𝔢𝔢𝔩 😭
Crazy stuff! Looks really weird :D
Which lake is it?
The dead shore ☠️
Goo Lagoon
They killed the poor guy. He accidentally dies in a helicopter crash after this discovery
le goo lagoon
goo lagoon
What country is this?
Reminds me mades in abys.
I feel scary..weird
can anyone tell me how they filmed it
Two small manned subs.
With a camera.

Hahaha! 😂

Forbidden pasta
What is the scientific name for this species of cutthroat eel?
Like spongbob
6 ¶ Then God said, “Let there be a firmament in the midst of the waters, and let it divide the waters from the waters.”
7 Thus God made the firmament, and divided the waters which were under the firmament from the waters which were above the firmament; and it was so.
Genesis 1
1:20 "not givin a fuck... sorry mate"
The narrator sounds like colin baker
What is brine pool ?

Somewhere in the Gulf of Mexico

I ❤ This creepy but.. Cool 😉 much love Sexy Grandma Darkness ✌💙💙
Creepy but cool, true! 😊👍🏼
How deep are ya'll?
I am here from tiktok posting
My big question is shouldn't life at these depths be harmed in some way by the bright camera and submarine lights? Anything that lives down there has never ever seen light except for the odd glowing creature or something. So shouldn't lights like this harm them?
Well they're used to no light so they are basically all blind, they would have no way to take damage
kentknightsrule that makes sense
ok. SJW for everything. when u are watching this, u use electricity and it harms the planet. if u move or press something, the bacteria around u may die and be harmed. so dont move. dont breathe. just dont exist. thz
Niel Boshoff Animals (Marine life) deep underwater don't see light all that much, so they are practicly blind. What keeps them from being completely blind is the ability they aquire from being deep in the ocean. And that is glow in the dark body parts, so practicly bioluminesense. And they can see that bright light glow under the ocean that attracks them which is how most of those fish hunt their prey. Sharks are the same in some way, they are actually blind so if you shine a flashlight in their eye it wouldn't do anything to it, becuase sharks don't use their eyes to hunt they use their senses of movement and sound. Their is tons of videos on youtube showing this and explaining it, while some creatures can see light and are atrackted to it some don't see it at all. Also this is a good video to show case a game called "Subnautica" and how the ocean is in that game compared to our ocean it's pretty amazing and great game
@@aungkyawmin9456 What the hell are you on about, it's a fair question to ask about life this deep underwater.
This is dddeeeeppp stttuuffff
Very horrible,😱😱😱😱
Nightmare shit!
Very confused 🤔 What exactly happened there?
Its a section of the ocean that has an extremely high salinity (high salt) which they swim into the high salinity water their nerves and muscles go crazy, google 'brine pools' for abit more info

It almost died
@@tidalblue2739 OKAY, LOOKS LIKE YOU ARE CLEAN BANDIT FAN...
8 And God called the firmament Heaven. And the evening and the morning were the second day.
I loved the episode, but I've just gotta say the horror music with the creepy voices added in was unnecessary.
That eel lied himself into a knot out of pain because he spent 10 seconds in there. I think the creepy music is adequate
The sound effects are trash
Proof positive that there was a "creator". And that he had no idea what he was doing.
If you love nature, you should love the creator even more. Seek Jesus for forgiveness of your sins. Repent, He loves you but He is just and will judge righteously, repent.
Fake. This is not a blue planet scene.... this is the first trailer from Prometheus 3. :)
I hate bbc
Tubelight Gustii haha thanks for the laugh 😄
nice smile there
What a useless comment
