Found at 27, 000 under the sea

In a hostile realm of the ocean, where the pressure is over 830 times greater than on Earth's surface, scientists spotted a fish casually swimming around. No big deal.
It's a curious-looking snailfish, and at 27,349 feet (8,336 meters) down, it's the deepest fish ever observed. Researchers spotted the critter on a deep sea expedition in the Izu-Ogasawara Trench, located south of Japan, after lowering a camera with bait down into the ocean's "hadal zone." This cryptic region is named for the Greek god of the underworld, and is home to the deepest of the seas. The record-breaking observation, announced in early April 2023, was made by scientists at the University of Western Australia and Tokyo University of Marine Science and Technology.
Even at such remote hadal depths, researchers noted that snailfish generally spotted in the region were a "large and somewhat lively population of fish." Yet how might these animals survive such crushing pressure and isolated conditions? The answer is that snailfish, like this deepest-observed fish of the genus Pseudoliparis, are fantastically strange, with clever adaptations.
"Overall, very deep sea fishes (those living in the abyssal and hadal zones) tend to be small, flabby or jelly-like, eel-shaped fishes living slow lives, [that] like to binge eat and hunt using the blue light of their prey," Jessica Arbour, a biologist at Middle Tennessee State University, told in an email.
Amazing creature found 27,000 feet under the sea. Here's how it survives.
