The Mariana snailfish or Pseudoliparis swirei, is the deepest fish species collected from the ocean floor.
The snailfish thrives at depths of up to about 8,000 meters (26,200 feet) along the Mariana Trench near Guam.

Mackenzie Gerringer, a postdoctoral researcher at the University of Washington, said:
“This is the deepest fish that’s been collected from the ocean floor, and we’re very excited to have an official name.
They don’t look very robust or strong for living in such an extreme environment, but they are extremely successful.”
