Description

The Notched flathead is a flathead (Platycephalidae) from shallow coastal water of the Indo-West Pacific. The species grows to about 15 cm and has a strongly flattened, rearward-tapering, sandy body with a broad, bony, spiny head and eyes on top of the head. As an ambush predator it lies half-buried on sand and mud bottoms and seizes passing small fish and crustaceans. The sharp head and gill-cover spines can give a cut when handled.
