Ghost fish is the best diver

Science Illustrated - - SCIENCE UPDATE -

ZO­OL­OGY Only twice as long as a ci­gar and equipped with wafer thin skin, so you can see its liver from the out­side. The fish that lives at the low­est ocean depths does not look very tough nor able to re­sist the huge wa­ter pres­sure at depths of 8,000+ m.

Nev­er­the­less the fish, Pseu­doliparis swirei – also known as the Mariana snail­fish – has now of­fi­cially been named the world's deep­est fish, af­ter sci­en­tists took a closer look at it and named the species based on spec­i­mens col­lected in the Mariana Trench.

The fish was orig­i­nally spot­ted at un­be­liev­able depths back in 2014, when it un­of­fi­cially beat the pre­vi­ous record holder, which is also a snail­fish.

In or­der to give the new snail­fish an of­fi­cial name and a ti­tle, sci­en­tists first had to an­a­lyse col­lected ver­sions of the fish. This has now been done, and the ti­tle has been claimed. Re­cently, a Ja­panese deep sea mis­sion filmed a group of snail­fish swim­ming about at a depth of 8,178 m in the Mariana Trench, and that is the new of­fi­cial world record.

Al­though the deep­est place of the ocean reaches al­most another 3 km into the abyss, it is, ac­cord­ing to marine bi­ol­o­gists, un­likely that we will ever spot fish at much lower depths than the Mariana snail­fish. This is due to the fact that the pres­sure is so in­tense that the fish will be un­able to pre­serve the chem­i­cal com­pounds such as pro­teins in­side their bod­ies.

A fish has been ob­served at a depth of 8,178 m in the Mariana Trench. It is now of­fi­cially the world's deep­est-swim­ming fish.
