Description

The scaldfish is a small, thin flatfish of the family Bothidae reaching about 25 cm. Unlike plaice and sole the scaldfish is left-eyed: both eyes lie on the left side, which is brownish and spotted, while the underside is white and translucent. The scaling is thin and sheds easily, giving the species its unflattering name. It lives on sand and mud bottoms of the north-eastern Atlantic, the North Sea and the Mediterranean, from shallow water to two hundred metres. On the bottom it hunts small crustaceans, worms and small fish. Because of its small size and thin body it has no culinary or commercial value, but it is a common inhabitant of sandy sea bottoms and prey for larger fish.
