Description

The deepwater flathead is a bottom fish of the flathead family (Platycephalidae) from the temperate waters around southern Australia. The species grows to about 70 cm and has a strongly flattened head and an elongate, sand-coloured body that camouflages it on the bottom. It lives on the continental shelf and upper slope at considerable depth. As an ambush predator it lies half-buried and seizes passing fishes, crustaceans and squid. The deepwater flathead is a valued commercial fish. Handle the head spines with care; otherwise it is harmless to humans.
