Researchers have found the deepest living fish ever discovered, a sea ghost, at a staggering depth of 26,716 feet – over 5 miles deep. The Mariana Trench located in the Western Pacific near Guam hosts the deepest place on earth, and has been the focus of high profile voyages to conquer its deepest point, Challenger Deep. A recent expedition to the Trench onboard Research Vessel Falkor targeted multiple depths and found active thriving communities of animals. The expedition set many new records such as the deepest rock samples ever collected and new species including the deepest fish ever recorded.
A compilation of video footage captured from the University of Aberdeen’s Hadal-Lander in the Mariana Trench from 5000m to 10,545 m deep. The large fish inhabit the shallower depth (5000 to 6500m) are rat-tails, cusk eels and eel pouts. At the mid depths (6500 to 8000m) are the supergiant amphipods and the small pink snailfish. The fragile snailfish at 8145m is now the deepest living fish. At depth greater than 8500m, only large swarms of small scavenging amphipods are visible. The footage was taken during the HADES-M cruise on Schmidt Ocean Institute’s Research Vessel ‘Falkor’.
