Description

The leopard flounder is a flatfish of the lefteye flounder family (Bothidae) from the Indo-Pacific. The species grows to about 39 cm and has a round-oval, flattened body with both eyes on the left side and a handsome pattern of rings and blue spots on a sand-coloured eyed side, camouflaging it excellently; it can quickly match its colour to the substrate. It lives on sand, silt and mud bottoms of inner reef flats and lagoons. As an ambush bottom hunter it seizes small fishes and crustaceans. Males have an elongated pectoral ray. The species is harmless to humans.
