Description

The Nigerian tonguesole is a long, tongue-shaped flatfish of the family Cynoglossidae (tonguefishes) reaching about 40 cm. The narrow, rearward-tapering body has a rounded, hook-shaped snout; the dorsal, tail and anal fins merge into a continuous fringe. Both eyes lie close together on the left side of the head. The species lives on sand and mud bottoms of turbid coastal water and estuaries along the West African coast. On the bottom it searches, mainly at night, for worms, small crustaceans and molluscs. With its fine flesh it is a valued commercial fish in West Africa, landed by the coastal fishery.
