Description

Grohmann's scaldfish is a small, left-eyed flatfish of the family Bothidae reaching about 12 cm. Both eyes lie on the left side, which is sandy-brown and bears a few dark spots; the thin, translucent skin through which the bones show is characteristic of the scaldfishes. The species lives on sand and mud bottoms of the continental shelf of the Mediterranean and the adjacent eastern Atlantic, where it presses against the bottom and partly buries itself. On the bottom it hunts small crustaceans and worms. Like all flatfish the young start symmetrical and, after metamorphosis, sink onto their side to the bottom. Because of its small size it has no fishery importance, though it regularly comes up as bycatch.
