Seemingly "Cute and Normal Aquarium Fish" Thrives in the Deepest Parts of Mariana Trench!

Fact #1: Mariana Trench is deep.

Fact #2: So deep that if Mount Everest were dropped into it, you can still enjoy its mile depth before you reach the mountain's peak.

With that in mind, have you ever thought of what's life like under it?

As the deepest part of the world’s oceans, Mariana Trench has undeniably extreme conditions to live in. The area’s so dark that no light from the sun ever reaches it. At just 10,000 meters deep (keep in mind, that's not the trench's deepest yet), an unmanned deep-sea submarine crumbled due to high pressure.

And its deepest point? Just imagine "having an African elephant stand on your big toenail"--that's how pressurized it is.  We, humans, can already be incapacitated at just under 250 meters of water!

And yet there are this beautiful warriors--there is life down there. Even at extreme pressures, a number of creatures were able to keep on existing as if they're just surviving a normal day at work. From acorn worm that keeps on sinking into the sand and isopods with their long legs, to flying saucer-like jellyfishes that seems so hypnotic, marine animals thrive along those surfaces like secret strong aliens.

One that might really catch people's attention is this cute snailfish. This light skinned tadpole-looking creature was recorded on May 18, 2017 to be the deepest living fish ever to be seen. In a video shown from the Japan Agency for Marine-Earth Science and Technology, they found this specie at 8.1 kilometres down, eating the rotting mackerel bait that was attached outside their compact landers. Such sighting beats the reigning record in 2014 for the deepest live fish sighting by 33 meters!

What's more surprising is they look just like a normal fish in a home aquarium! And to be honest, it even looks like something I'd have as a pet! Just look at it gracefully go.

Theoretically, fishes cannot survive at depths more than 8.2 kilometres as the extreme pressure kills them. But these snailfish just easily dangles at the line for a treat. Now the question still remains--how? How did they do it?
