Description

The thickback sole is a sole-like flatfish of the family Soleidae reaching about 35 cm. Like the true sole it lies on its side with both eyes on the right side; characteristic is a row of broad, dark cross-bands over the brown upper side, often alternating with paler bands. The rounded snout and the continuous fin fringe around the body are typical of the soles. The species lives on sand and mud bottoms of the continental shelf and slope of the north-eastern Atlantic and the Mediterranean, from tens to several hundred metres. On the bottom it eats bristle worms, small crustaceans and molluscs. Because of its modest size it has limited commercial value, though it is locally eaten.
