Scientists capture footage of world's deepest fish off Japan.

Scientists from the University of Western Australia and the Tokyo University of Marine Science and Technology have captured footage of the "world's deepest fish" using baited robotic cameras. The young snailfish was filmed at a depth of 8,300 meters below the surface in the Izu-Ogasawara trench south of Japan, setting a world record for the deepest fish ever recorded on video. The research initiative, which lasted two months, focused on deep-sea fish populations in three trenches located near Japan. The snailfish belongs to an unknown species and is part of the Pseudoliparis family.
