Description

[edit]

The shark is elongated in appearance. It has a relatively short snout. The anal fin is relatively short and the pectoral fins are low down. On its ventral snout, there are oval-shaped series of ampullae of Lorenzini. The shark is uniformly brown.[1]

The specimen caught was 58 cm (23 in) long.[1]

Distribution and habitat

The species lives in very deep water, the only specimen was caught at the Bear Seamount in the north-western Atlantic Ocean at a depth of 1,800 m (5,900 ft).[1]

Similar species

[edit]

It is most similar to the black roughscale catshark (Apristurus melanoasper), but Galbraith's catshark is smaller, the anal fin is shorter, the shape is different and the denticles are of different sizes.[1]
