Description

The Serrate flathead is a flathead (Platycephalidae) from shallow sand and mud water of the Indo-West Pacific. The species grows to about 15 cm and has a strongly flattened, elongate, sandy body with a broad, flat head, high-set eyes and spines on the head and gill cover. As a motionless ambush predator it lies half-buried and camouflaged on the bottom and snaps at passing small fish and crustaceans. The sharp head and gill-cover spines can give a puncture wound when handled.
