Description

The dwarf flathead is a flathead (Platycephalidae) from the western Pacific. The species has a strongly flattened head and an elongate body, a build suited to a buried life on the bottom; its sand-coloured pattern makes it nearly invisible. It lives on sandy bottoms of shallow to moderately deep coastal water. As an ambush hunter it waits half-buried for small fishes and crustaceans. The sharp spines on the gill cover can cause cuts when handled.
