Cuskeel, Barathrites sp - Australian Museum

ANIMAL SPECIES:Cuskeel, Barathrites sp

The specimen of Barathrites sp was collected in April 1989 by staff of the Australian Museum Fish Section working on board the H.M.A.S Cook. It was caught in a midwater trawl at a depth of 3300 m (bottom depth 3490 m to 4840 m) in the Tasman Sea off Sydney, New South Wales. It is currently registered in the Fish Collection of the Australian Museum (AMS I.28746-002). The semi-circular mark on the side of the body is a tag recording the registration number of the specimen.

Identification

The genus Barathrites is classified in the family Ophidiidae (the cuskeels). These fishes are mostly elongate, have smooth scales, and are oviparous (egg-laying). Their pelvic fins are reduced to one or two rays or absent. The single dorsal fin is usually continuous with the caudal and anal fins.

The family Ophidiidae contains about 165 species in 50 genera. Many live in the deepsea, and include the deepest living fish known, Abyssobrotula galatheae. This fish grows to about 20 cm in length, and has been recorded from 8370 m in the Puerto Rico Trench.
