Inhabits river estuaries and shallow coastal marine waters over sand bottoms, often associated with seagrass beds. Also occurs in salt marshes and tidal pools of high salinity. Feeds mainly on crustaceans and fishes. An important food and sport fish throughout its range. Utilized fresh for steaming, broiling and baking (Ref. 9988).
