Description

The naked sole is a small flatfish of the American sole family (Achiridae) from the western Atlantic. The species grows to about 18 cm and has an oval, strongly flattened body with both eyes on the right side and a nearly scaleless skin, to which its name refers; the eyed side bears narrow dark crossbars. It lives on soft sand and mud bottoms, where it hides half-buried. As a bottom hunter it feeds on small benthic invertebrates. Owing to its small size the species is of little fishery interest and is harmless to humans.
