Description

The peacock flounder is a left-eyed flatfish of the family Bothidae (lefteye flounders) reaching about 46 cm. The brown upper side is studded with blue rings and spots, hence the name; the fish is a master of camouflage and adapts its colour and pattern to the substrate in a flash. Both eyes lie on the left side and can move independently; in the male the eyes are set far apart. The species lives over sand, rubble and seagrass bottoms near reefs of shallow coastal water in the western Atlantic and the Caribbean. Half-buried it lurks as an ambush predator for small fish, crustaceans and squid. It is a favourite subject for divers and a locally valued food fish.
