A camouflaged species that tolerates water with low saltiness; occurs frequently in brackish bays and estuaries, even on occasion in fresh water. Adults are found mostly over mud bottoms in estuaries and coastal waters to about 120 feet (40 m) depth. Taken by anglers inshore from bridges, jetties and small boats. They move to deeper water in winter, but are still easily accessible. Adults feed chiefly on fishes, also on crabs and shrimps. Juveniles eat mainly small bottom-living invertebrates.
