Abyssobrotula galatheae is a species of cusk eel in the family Ophidiidae. [1] [3] It is the deepest-living fish known; one specimen, trawled from a depth of 8,370 m (27,460 ft) in the Puerto Rico Trench in 1970, holds the record for the deepest fish ever captured. [4]
The theoretical maximum depth for fish is at about 8,000–8,500 m (26,200–27,900 ft), beyond which they would become hyperosmotic. [ 22 ] [ 23 ] [ 24 ] Invertebrates such as sea cucumbers , some of which potentially could be mistaken for flatfish, have been confirmed at depths of 10,000 m (33,000 ft) and more.
Because of the high pressure, the depth to which a diver can descend without special equipment is limited. The deepest recorded descent made by a freediver is 253 m (830 ft) as of 2012. [22] The scuba record is 318 m (1,043 ft) as of June 2005, [23] and 534 metres (1,752 ft) on surface supply on the Comex Hydra 8 experimental dives in 1988. [24]
The world's deepest fish ever filmed has been caught on camera by scientists from The University of Western Australia (UWA) and Japan at a depth of more than eight kilometres underwater. An ...
This is possibly the depth record for a fish caught on the seafloor. [ 2 ] [ 6 ] Abyssobrotula galatheae has generally been recognized as the record-holder based on one caught at the seafloor at 8,370 m (27,460 ft), but it might have been caught with a non-closing net (a net that is open on the way up and down into the deep) and therefore was ...

They are often referred to as "doomsday fish" because of their mythical reputation as earthquake or natural disaster predictions. In the months preceding the 2011 earthquake, 20 oarfish were ...
A 2006 study by Canadian scientists has found five species of deep-sea fish – blue hake, spiny eel – to be on the verge of extinction due to the shift of commercial fishing from continental shelves to the slopes of the continental shelves, down to depths of 1,600 metres (5,249 ft).
