Adults occur in coastal waters (Ref. 9283). They are common in shallow water and feed mainly on mollusks, but also take crustaceans and small fishes (Ref. 9283). Juveniles are frequently encountered in estuaries and feed on a variety of benthic invertebrates (Ref. 9283). Marketed fresh and salted or dried (Ref. 9283).
