n.
or croaker
In biology, any of about 160 species (family Sciaenidae) of carnivorous, generally bottom-dwelling fishes.
Most are marine, found along warm and tropical seashores. Most can "vocalize" by moving strong muscles attached to the air bladder, which acts as a resonating chamber, amplifying the sounds. Drums have two dorsal fins and are usually silvery. The weakfishes , sea trouts, and squeteagues (genus Cynoscion ) have a large mouth, jutting jaws, and canine teeth, but most drums have an underslung lower jaw and small teeth. The largest species, the totuava, weighs up to 225 lbs (100 kg), but other species are much smaller. Many drums are food or game fishes. See also bass , kingfish .
