Description

The knifejaw is a perch-like fish of the knifejaw family (Oplegnathidae) from the temperate waters around southern Australia. The species grows to about 45 cm and has a deep, silvery-grey body; juveniles often bear dark bars that fade in adults. Characteristic is the mouth, in which the teeth are fused into a strong, parrot-like beak with which the fish breaks open hard prey. It lives on the continental shelf and upper slope and feeds on crustaceans, molluscs and sea urchins. Owing to limited data the species is assessed as Data Deficient (DD). It is harmless to humans.
