9 Sea Animals Scientists Are Terrified to Cage

Fossil Fruw – After Dark

Some of the ocean's deadliest and strangest creatures have never survived inside a human made aquarium, and the reasons why are darker than you'd expect. In this video we break down nine sea animals, from the great white shark to the colossal squid, that prove some things simply cannot be taken out of the sea. You'll learn why great white sharks die within days of captivity, why the vampire squid could not be kept alive even by the Monterey Bay Aquarium, why orcas like Tilikum turned violent in captivity, and why narwhals, leatherback turtles, leopard seals, oarfish, and sperm whales are considered impossible to keep on display. This is a deep dive into marine biology, ocean horror, and the science behind why apex predators and deep sea creatures cannot survive outside their natural habitat.

If you love ocean mysteries, deep sea creatures, shark facts, and true stories about dangerous marine animals, this video is for you. Make sure to subscribe for more natural history, ocean documentary style content, and prehistoric and modern animal deep dives.

Which sea animal would you be the most horrified to be in a tank with? 💀 (Hype, subscribe, and like the video if you enjoy :D )

Also no ai images, video, or voice were used in this video.

Sensory deprivation is a hell of a thing, which is why it's considered a war crime and inhumane.

The sad part is they will keep the shark caged for days until they die instead of releasing them once they see its not going to work out, that is human arrogance & ego at play.

There are no documented cases of a wild Orca killing a human, only captive ones.

The collosal squid was recorded LAST YEAR, thats how hidden they are and how deep they stay

It's cruel, no wild animals should be caged, especially ocean ones. Leave them alone 😭

Killer whales are ripped from their families. Extreme trauma is what causes their minds to go in captivity. They're not evil and they don't attack people in the wild

I remember seeing the Vampire Squid at the aquarium, I can remember that it was only a small circular window like a ship port hole that you could view the squid

Keeping any ocean animal inside a tank is barbaric and should be illegal. No Orca is the wild ever attacked a human, let alone kill them, only those in captivity and they had every reason to.

The sperm whale part is the one I keep coming back to 🐋 Its entire life happens a kilometre down in total darkness, built out of sound rather than light. Even with a tank the size of a stadium, you couldn't give it the one thing it actually needs — enough distance for its own voice to travel out and come back. You'd be keeping the body and throwing away the world it lives in.

What makes you think marine biologist and researchers need to cage an animal to study them? They are best studied in their natural habitat.

as a californian the Monterey bay aqaurium has held a GW shark for the longest recorded time before choosing to release it back I was one of a few many who were able to see her

To anyone wondering about the creepy beluga, the eyes are on the side of the mouth, the hollow eyes your seeing is enhanced shadows caused by its blubbery head, and not eyes. They are actually very cute in real life, you have no need to fear them!

There was no Orca named Nuka 3 involved in any death. However Nootka IV was in the same tank as Tilikum and Haida 2 (also misspelled here) at the time of Keltie Byrnes death. If they get the stuff wrong you can easily look up, don't trust the rest.

I LITTERALLY cried during the narwhal bit cuz I love narwhals

No wild animal should ever be tanked, or caged, Sea wolrld should be shut down.

Thumbnail looks like the animal is about to drop a hard rap album.

These poor animals, especially orcas who are kept in captivity, they aren't naturally born to hunt humans but they will kill a human especially if kept in a tank and forced to preform tricks like a dog. Then ppl are shocked when a captive trained orca kills a trainer, an orca who was forced to live in misery and stress. Then ppl mourn the death of the trainer and say the orca should be put to death. That's like walking into a lions den, getting maulled to death and then blaming the animal for what? Doing what it naturally does? For mentally snapping and killing a trainer after years of abuse?.

10:10 no animals should be kept captive for our own pleasure 🤦🏽‍♀️🤦🏽‍♀️😭😭😭 and if it is for scientific reason please be careful and respect them or don't do research on them 🩷 and taking a picture with a dead animal is so weird
