Occurs on sandy bottom. Feeds on shrimps, crabs, other crustaceans, squid, bivalves and small fishes. Produces loud, drumming sound by vibrating its swim bladder (Ref. 9988). Used both for food and fish meal; other uses include bait for lobster traps and flatfish, handlines, pet food and fertilizer. Utilized fresh and frozen; also used for caviar ; can be broiled and baked (Ref. 9988).
