Description

The spot croaker is a silvery croaker of the family Sciaenidae (drums) reaching about 36 cm. The sturdy, silvery-grey body bears oblique yellow streaks over the back and a conspicuous dark, round spot just behind the gill cover, from which the species takes its name. Like other drums it can make sound with muscles against its swim bladder. The species lives in schools in estuaries, bays and coastal water along the east coast of the USA and the Gulf of Mexico and tolerates strongly varying salinities. On the bottom it searches for worms, small crustaceans, molluscs and detritus. Young fish grow up in the estuaries. With its tasty flesh it is a popular commercial and sport fish.
