Found usually over sandy or muddy bottoms in coastal waters to about 60 m depth. Occurs in nursery and feeding grounds in river estuaries during summer and fall. Juveniles often stay in the estuarine waters throughout the year. Feeds mainly on worms, small crustaceans and organic detritus. A small specimen of this species was caught in Tokyo Bay, Japan, probably brought in with the ballast water of a ship (Ref. 10325).
