The smallmouth spiny eel (Polyacanthonotus rissoanus), also called the shortspine tapirfish, is a species of deep-sea spiny eel.

Description

The smallmouth spiny eel is silver or brown in colour, with a maximum length of 36 cm (14 in). It has 26–36 dorsal soft rays. It looks similar to Polyacanthonotus africanus but its lateral line is lighter and less distinct. It has a small mouth and a short preoral snout. Mature males are distinguished by their black nostrils.

Habitat

The smallmouth spiny eel lives in the Arctic waters off of Canada and in the North Atlantic Ocean off of Iceland, Ireland and Great Britain; it has also been observed in the waters off South Africa and in the Tasman Sea. It is a benthic and bathydemersal species, living at depths of 500–2,800 m (1,600–9,200 ft).

Behaviour

Polyacanthonotus rissoanus feeds on coelenterates, worms and crustaceans.
