On Tuesday, a team of scientists finally discovered and documented the species of fish that can survive about 5 miles underwater, a record. Its official name is Pseudoliparis swirei, a pink little snailfish which they caught about 7,966 meters in the Mariana Trench. The region where this odd little creature lives is known as the hadal zone. It’s interesting that experts caught it for the first time back in 2014 and then again, this year. However, they are only now officially describing it.
This is the deepest fish that has ever been collected from the sea and its looks might not be what people expected from such a creature of the dark. According to Mackenzie Gerringer from the Unversity of Washington’s Friday Harbor Laboratories, people often imagine a black, monster-like fish. Actually, when you are this deep down, the creatures there begin looking a bit different. They no longer have those big teeth and scales.

The Pseudoliparis swirei is actually one of the two species of snailfish experts managed to film during their recent expedition. There are actually over 350 species of snailfish in the entire world. The team successfully caught 37 individuals and filmed one at about 8,178 meters deep.
However, they still haven’t managed to catch an individual from the other snailfish species. It only made an appearance on BBC’s Blue Planet 2 documentary. This fish is so delicate that some scientists have compared it with a tissue in the water. It’s so mysterious that it doesn’t even have a formal name. Experts have only nicknamed it the “ethereal snailfish”.
The Pseudoliparis swirei snailfish has a pale pink color and is twice as long as a cigar. Also, the water pressure it can withstand is greater than the weight of 1,600 elephants sitting on its head. It’s also transparent and you can see its internal organs.
