Summary

Description

An oval, deep bodied fish with large eyes. Maximum recorded size 30 cm, with males being smaller than females. The snout is concave and long, with a protrusible mouth forming a short tube. Dorsal spines are strong and long. Anal spines are short and thin. The pelvic fin has a strong spine with five stout soft rays but these do not extend very far beyond the 2nd anal spine. The boar fish has small scales which are rough to touch. Individuals of Capros aper from deep water of 200 m or more are a brick red colour, sometimes with yellow bars. Shallow water specimens are often yellow or straw coloured.
