Description

The Japanese tongue sole is a tongue sole from the northwest Pacific, off Japan, Korea and China. The species grows to about 36 cm and has a strongly flattened, tongue-shaped, dark-brown body with both eyes on the same side and fringed lips. As a bottom-dweller it lies half-buried in sand and mud bottoms of coastal water, between about 20 and 65 metres, and searches for small worms and crustaceans. It is a valued food fish. The IUCN has not evaluated the species.
