Description

The rock flathead is a flathead of the family Platycephalidae from the temperate waters around southern Australia. The species grows to about 50 cm and has an elongate body with a strongly flattened, broad head and eyes on top of the head, adapted to a bottom life. It occurs inshore and over reefs, often in seagrass beds. As an ambush bottom predator it lies half-buried or motionless in wait and seizes small fishes and crustaceans. The rock flathead is a valued angling and food fish. The head bears a few sharp spines; otherwise it is harmless to humans.
