Description

The European flounder is a right-eyed flatfish of the family Pleuronectidae reaching about 60 cm. The eyed side is brown to greenish-brown with faint blotches, the blind underside white; rows of rough bony tubercles run along the base of the dorsal and anal fins and the lateral line, giving the fish a rough feel. The flounder is remarkable for tolerating fresh, brackish and salt water and can occur far up rivers. It lives on sand and mud bottoms of the North Sea, Baltic and Atlantic coast and eats shellfish, worms and small crustaceans. In winter it migrates to sea to spawn. It is a valued food fish.
