Description

The fringe-eye flathead is a flathead (Platycephalidae) from the Indo-West Pacific. The species has a strongly flattened head and an elongate body with a mottled, sand-coloured pattern; over the eyes it bears fringe-like skin flaps (eye flags), to which the name refers. It inhabits shallow rocky coastal areas, often near seaweed beds and mangroves, usually at less than a few metres depth. As an ambush hunter it lies partly buried on the bottom and springs on small fishes and crustaceans. The species is harmless to humans.
