Description

The starry flounder is a large flatfish of the family Pleuronectidae reaching about 91 cm. Characteristic are the striking black-and-white or black-and-orange banded dorsal, caudal and anal fins and the rough, star-shaped bony plates scattered over the brown upper side, which give the species its name. The eyes usually lie on the left side, but in this species both left- and right-eyed individuals occur. The species lives on sand and mud bottoms of coastal water, estuaries and river mouths in the northern Pacific and ranges far into fresh water. On the bottom it searches for worms, molluscs, crustaceans and small fish. With its tasty flesh it is a valued sport and market fish.
