Description

Symphurus plagusia, the duskycheek tonguefish, is a small flatfish of the family Cynoglossidae (tonguefishes) from the western Atlantic. The species has a tongue-shaped, strongly flattened body with both eyes on the left side and the dorsal, caudal and anal fins fused into a continuous fringe; it reaches about 25 cm. It lives in shallow water on mud and sand bottoms, often near river mouths, where it partly buries itself. The diet consists of small bottom invertebrates such as polychaete worms and crustaceans. The species is landed locally as bycatch but is of limited commercial importance.
