Description

The longfin pike is the only species of the family Dinolestidae and occurs in the temperate waters around southern Australia. The species grows to about 84 cm and has an elongate, silvery, pike-like body with a large mouth with fine teeth and large eyes. It forms schools in bays over rocky reefs and in seagrass beds. As a fast, nocturnal predator it hunts small schooling fishes and crustaceans. The longfin pike is a local angling and food fish. Despite its pike-like appearance and teeth it is harmless to humans.
