Why Animals Get Creepier the Deeper You Go

The fact that these creatures cannot go up the surface without popping like a balloon, and no man-made machine can meticulously study these creatures beneath the seafloor is the exact definition of so close yet so far and it's both equally terrifying and amazing.

When I look a deep sea animals today, it makes me think of what kind of deep sea creatures existed back in different time periods of earth’s history, it could be stuff we have never even imagined being possible

It's crazy to me that a submarine got absolutely obliterated at 3500-4000m, yet a fish can just chill at 8000m comfortably. They are differently biologically but god damn that's just ridiculous

12:20 Everything in the depths looks like a lovecraftian horror... Except this fish for some reason. Looks like a big goofy Axolotl.

In my humble opinion, the freakiest deep sea animal has to be the barreleye. Even without knowing that they can rotate their eyes like that (I learned something new today!), it's just the weirdest that they have their eyes inside of their head. It upends our intuition about what eyes are and how they work in a way that no other animal does. That's why, to me at least, there's not even a competition about which animal is the freakiest.

It's not "survival of the fittest" as much as "survival of whatever works well enough," leading to a multitude of strange adaptations and mysterious animals in our planet's deep oceans.

12:41 What? That fish is adorable!

I have a PhD in biology and this channel still manages to consistently blow my damn mind! Love it!

Deep sea animals are fascinating! Our camera crew talked to the Monterey Bay Aquarium Research Institute, the pioneer of deep ocean exploration, and their amazing findings, including the barrel eye fish and one of the few dragonfish ever to have been seen alive. What's extremely interesting is to see and understand how scientists are able to capture these creatures and analyse their light-making abilities. Thanks to that, we were able to understand the three reasons why these creatures use bioluminescence.

When I was a kid, whenever I'd feel small or lonely...I'd look up at the stars. Wondered if there was life up there. Turns out I was looking in the wrong direction. When alien life entered our world, it was from deep beneath the Pacific Ocean...

I used to read and look at pictures from a book about sea animals at my grandparents', and it had some of these animals. It was fascinating. Makes you wonder what other species have existed without us knowing.

We know very little about the behavior of deep-sea animals. This can make them seem even more mysterious and even creepy. For example, some deep-sea fish have been known to emit bioluminescent flashes of light. The purpose of this behavior is unknown, but it has led to speculation that these fish may use their light to communicate with each other or to attract prey.

Magnapinna is definitely one of the most intriguing animals down there! There's a video where one quickly and violently swings its arms in different directions, almost like it's hunting, making it look even more mysterious and horror-like than it does moving normally

Something about the bottom of the ocean feels like a 'cold, corrupted wasteland mirror' version of the surface. It's hard to put into words, but is surreal.

I’ve always found that fascinating, ever since I was a child, reading old encyclopedias, before the wiki-boom. To know that the most weird and creepy creatures lived in the underworld was bone chilling.

8:30 I have always wondered what pushed the first species to leave the sea to explore lands... Now I know... FEAR

Just finished playing Dredge a little while ago. Didn't realize that game's fish are all real till I saw this. Thought some were made up, but I was obviously wrong. I was able to identify many from the game in the video. Which is pretty cool.

I'm an engineering student but I've always found the sea really interesting specially the deepest of it, there's so many varieties of creatures and the idea that there's a lot more out there that we don't know about it's intriguing

Definitely need a part two of that! The depth really is beautiful and scary

One of my favorite deep sea animals is the black dragonfish. I can't help but find that it looks strickingly similar to the monster from Alien, and at the same time is mesmerizing and beautiful. I know that it may sound weird because it's not exactly something that most people would deem to be beautiful, but there's just something about it that makes it very intriguing and captivating to me. Its hunting mechanism is somewhat similar to the angler-fish, but at the same time its whole body can glow and it has transparent teeth that make it impossible for its prey to see as it swims right to their doom
