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’.
