New record for deepest fish ever caught and filmed
Scientists have tracked species of snailfish at more than 8,000 metres of depth in the Japan Trench

Two snailfish, of the Pseudoliparis belyaevi species, were caught in traps set 8,022 metres underwater in the Japan Trench, south of Japan, during a two-month voyage by a team from the University of Western Australia (UWA) and the Tokyo University of Marine Science.

Scientists have also recorded a juvenile specimen of an unknown species of snail fish swimming 8,336 meters deep in the Izu-Ogasawara trench off southern Japan. The footage was possible thanks to remote cameras, as part of a ten-year study on the deepest fish population on the planet. Prof. Alan Jamieson, the expedition's chief scientist, says it is vital to conduct more deep-sea research to understand human impact on the ocean. 

Much remains to be learned from exploring the mysteries of the deep: more than eighty percent of our ocean is unmapped, unobserved, and unexplored. New discoveries are expected from future expeditions.
