Marine; brackish; reef-associated; depth range 0 - 5 m. Subtropical; 43°N - 25°N, 82°W - 68°W
Western Atlantic: Cape Cod, Massachusetts to Florida in USA, straggling south to Miami in cold years.
Size / Weight / Age
Maturity: Lm ?  range ? - 38 cm
Max length : 43.2 cm TL male/unsexed; (Ref. 40637); max. published weight: 2.2 kg (Ref. 40637)
Largely inhabits inshore water on rocky bottoms and reefs, jetties and wrecks. Frequently occurs among litter and tolerates polluted water. Becoming important as an experimental fish because of its size and hardiness. Has been reared in captivity (Ref. 35422).
