What is the deepest-living fish?

The deepsea has long held a fascination for people.  What is the 'fishy depth record'?

A Cuskeel, Barathrites sp

The fish that currently holds the depth record is a species of cuskeel (family Ophidiidae) called Abyssobrotula galatheae. This 20 cm long fish has been collected from the Puerto Rico Trench at a depth of 8,370 m (27,455 feet).

The cuskeel in the upper image is Barathrites sp. It was collected at a "mere" 3,300 m. The fish is registered in the Australian Museum Ichthyology Collection (AMS I.28746-002). View the factsheet for this species.

Dr Shillito of the Universite Pierre et Marie Curie, Paris, France, recently used a new device called an abyss box to capture and bring live to the surface a deepsea zoarcid fish, Pachycara saldanhai. The fish was caught, and filmed, at a depth of 2,300 m on the hot vents of the Mid-Atlantic Ridge.
