The Blackcheek tonguefish (Symphurus plagiusa) is a fish that lives in both fresh and salt water of the family Cynoglossidae that grows up to 21 cm.
Description
The blackcheek tonguefish is a small, leaf-shaped flatfish of the family Cynoglossidae (tonguefishes) reaching about 21 cm. The elongate, rearward-tapering body has both eyes on the left side; the dorsal, caudal and anal fins merge continuously into a pointed tip. The upper side is brown and marbled, often with a dark spot on the gill cheek, the underside pale. Like all flatfish the larva starts symmetrical and tilts onto the bottom as it grows. The species lives buried on soft sand and mud bottoms of shallow coastal water and estuaries along the American Atlantic coast and tolerates brackish water. On the bottom it searches for small crustaceans, worms and molluscs.
