Description

Mertens's deepwater flounder is a very thin, translucent flatfish of the family Bothidae (lefteye flounders) reaching about 18 cm. Both eyes lie on the left side of the head; the pale, strongly compressed body is almost translucent and the mouth is notably small. The species lives on soft bottoms of the deeper continental slope along the West African coast, where it rests flat on the bottom. On the bottom it searches for small zooplankton and small crustaceans. Because of its deep lifestyle and small size it has no fishery value and is only rarely seen; records come mainly from deep-sea research and bycatch.
