Meet the deepest fish in the ocean, a new species named the Mariana snailfish

They don’t look very robust or strong for living in such an extreme environment, but they are extremely successful

n deep water, they cluster together in groups and feed on tiny crustaceans and shrimp using suction from their mouths to gulp prey. Little is known about how these fish can live under intense water pressure; the pressure at those depths is similar to an elephant standing on your thumb.
