Pogonias cromis

The black drum is a heavy-bodied fish that can grow past a metre and a half, though most divers meet smaller ones. It gets its name from the deep drumming sound it makes, produced by muscles on its swim bladder.
Also known as: oyster drum, drumfish, big drum, gray drum, sea drum, oyster cracker
Barred juveniles look like sheepshead, but the chin barbels settle it: black drum have them, sheepshead do not.
Adults are silvery grey to almost black, with dark pelvic and anal fins. Young fish show four or five bold black bars across a pale body, fading to plain grey as they grow. A cluster of short barbels, whisker-like feelers, hangs under the chin.
Black drum feed mainly on the bottom, crushing mollusks and crabs with strong, rounded teeth. Their chin barbels feel out food buried in sand or mud. In shallow water they sometimes feed head-down, with the tail breaking the surface.
Black drum reach maturity by the end of their second year and spawn in and around estuaries, the mixed salt-and-freshwater zones where rivers meet the sea.
Black drum make deep drumming calls between 100 and 500 Hz, produced with their swim bladder, when they gather to breed.
