"Abyssobrotula galatheae", a species of cusk eel in the family Ophidiidae, is among the deepest-living species of fish. In 1970, one specimen was trawled from a depth of 8370 meters in the Puerto Rico Trench. The animal was dead, however, upon arrival at the surface. In 2008, the hadal snailfish ("Pseudoliparis amblystomopsis") was observed and recorded at a depth of 7700 meters in the Japan Trench. These are, to date, the deepest living fish ever recorded. Other fish of the abyssal zone include the fishes of the family Ipnopidae, which includes the abyssal spiderfish ("Bathypterois longipes"), tripodfish ("Bathypterois grallator"), feeler fish ("Bathypterois longifilis"), and the black lizardfish ("Bathysauropsis gracilis"). Some members of this family have been recorded from depths of more than 6000 meters.
