Description

The southern flathead is a flathead (Platycephalidae) from the waters around southern Australia. The species has a strongly flattened head and an elongate, mottled body with sharp spines on the gill covers and high-set eyes. It is a shallow-water species of surf beaches, estuaries and bays, where it waits half-buried on soft bottoms. As an ambush hunter it takes passing small fishes and crustaceans. It is not venomous, but the sharp head spines can give a wound when handled.
