Description

The Japanese dragonet is a dragonet (Callionymidae) from shallow sand and reef water of the northwest Pacific around Japan. The species grows to about 6 cm and has a flattened, scaleless body with a triangular head, high-set eyes and a small, protrusible mouth; males often carry a high, ornate first dorsal fin. As a bottom-dweller it creeps over sand and rubble and picks small crustaceans, worms and fish eggs. The fish is harmless to humans.
