Description

The sand flathead is a flathead (Platycephalidae) from the temperate coastal waters of southern Australia. The species has a strongly flattened, broad head and a backward-tapering body, adapted to life half-buried on the bottom. It inhabits coastal waters from shallow bays and inlets to about 100 m deep, over sand, shell grit and mud bottoms. It is usually solitary but sometimes forms loose groups. As an ambush hunter it springs on small fishes and crustaceans. It is a sought-after sport and food fish and is harmless to humans.
