World's deepest fish found 7,966 meters down

Can any fish live deeper down than this ? Image Credit: YouTube / University of Washington
A new species of extremely deep-sea snailfish has been found in the depths of the Mariana Trench.
Discovered almost five miles beneath the surface, this ghost-like fish is around twice the length of a cigar and has skin so translucent that it is possible to see its internal organs.

At these depths, the pressure is so extreme that it is like having the equivalent weight of an entire elephant pressing down on every square inch of your entire body.

Below this depth, the pressure becomes so overwhelming that it can even destabilize proteins.

The new species, Pseudoliparis swirei, is named after an officer aboard the HMS Challenger which discovered thousands of new species during an expedition in the 1870s.

"We named this fish after him in acknowledgment of the crews that serve on oceanographic research vessels," said Mackenzie Gerringer, a postdoctoral fellow at the University of Washington.

"It takes a lot of people to keep a ship running and we wanted to sincerely thank them."

Considering the amount of pressure that exists at the bottom of the ocean.....this is truly amazing.

Yeah, I hear you on that. And from the article... At these depths, the pressure is so extreme that it is like having the equivalent weight of an entire elephant pressing down on every square inch of your entire body.

I used to live on Mt Tapochau on the island of Saipan in the Northern Marianas... the ocean is so crazy deep there that Tapochau  (at only 474m) is the highest mountain in the world when measured from the bottom of the ocean. Wikipedia will tell you it’s Mauna Kea, but that’s only 10,000 some meters... Tapochau is over 11,000 meters (474+10,994).

Tapochau is the tip of an enormous underwater mountain range that dwarfs the Himalayas. Did a lot diving when I lived on Saipan, lots of interesting ocean life around that area. Water is super clear in places. Dove the Shoun Maru in Rota and visibility was an amazing 300 feet (90m+)... got weird vertigo, diving down into that... felt like I was somehow falling up. http://www.diverota.com/dives/shoun-01hayashi.htm The CNMI chain also includes Tinian (of USS Indianapolis fame) ... though that’s the  kind of “interesting“ ocean life I’m not too interested in checking out.

Maybe they feed on the plastic waste no doubt littering the trench.
