Description

The Robust tonguesole is a tonguesole (Cynoglossidae) from shallow coastal and estuarine water of the northwest Pacific. The species grows to about 20 cm and has a strongly flattened, tongue-shaped body with both eyes on the left side, a down-curved mouth and a finely mottled, brown upper side for camouflage. As a bottom-bound fish it lies half-buried in sand and mud and searches for small worms, crustaceans and molluscs. The fish is harmless to humans.
