Description

The smallscale flathead is a flathead (Platycephalidae) from shallow sand and reef water of the Indo-West Pacific. The species grows to about 15 cm and has a strongly flattened head and an elongate, sand-coloured body, ideal for lying half-buried on the bottom. As an ambush predator it waits motionless and seizes passing shrimp and small fish. On the head and gill cover it bears sharp spines that can give a cut when handled.
