The flounder is one of the most common of the flat sea fishes, found along the shores of almost all countries. The body, which is extremely flattened at the sides, has the upper side dark and spotted and the under side white. Both eyes are on the upper side; and one is set lower than the other, giving the face a twisted appearance. The flounder is esteemed for its flesh.
