Description

Thor's scaldfish is a small, left-eyed flatfish of the family Bothidae reaching about 18 cm. Both eyes lie on the left side, which is sandy-brown and usually bears two conspicuous dark spots; the thin, translucent skin is characteristic of the scaldfishes. In the male a few front dorsal-fin rays are elongated. The species lives on sand and mud bottoms of the continental shelf of the north-eastern Atlantic and the Mediterranean, where it presses against the bottom and partly buries itself. On the bottom it hunts small crustaceans and worms. Because of its small size it has no fishery importance, though it regularly comes up as bycatch.
