Description

The winter flounder is a right-eyed flatfish of the family Pleuronectidae (righteye flounders) reaching about 64 cm. The oval body has both eyes on the right side, a small mouth and a thick, leathery skin; the upper side varies from olive-brown to almost black, matching the bottom. The species lives over sand and mud bottoms of cold coastal water and estuaries along the east coast of North America. In winter it moves into shallow bays and estuaries to spawn, hence its name. On the bottom it searches for worms, small crustaceans, molluscs and small fish. With its tasty flesh it is a popular commercial and sport fish, including for ice fishing.
