Spotlight: Miles Deep In the Mariana Trench, A New Fish Species Is Discovered

There’s exciting news coming out of the Mariana Trench’s mind-boggling depths. Deep sea explorers discovered a snailfish species living more than five miles — FIVE MILES! – deep in the Mariana Trench. It has been named the Pseudoliparis swirei, and according to this National Geographic article, “…scientists suspect they are unlikely to ever find a fish that lives much deeper.”

But it’s the deep sea, the least-explored part of our earth, so who can imagine what else marine researchers may find. As University of Washington marine biologist Mackenzie Gerringer notes,

“We think of it as a harsh environment because it’s extreme for us, but there’s a whole group of organisms that are very happy down there,” said lead researcher Mackenzie Gerringer, a marine biologist at the University of Washington. Further research in these depths may yield even more weird discoveries. “There are a lot of surprises waiting.”

This snailfish is about twice as long as a cigar, yet it can withstand more water pressure than 1,600 elephants standing on its head.
