Environment: milieu / climate zone / depth range / distribution range
Marine; freshwater; brackish; reef-associated; amphidromous (Ref. 55); depth range 5 - 180 m (Ref. 55), usually ? - 50 m (Ref. 9626). Subtropical; 42°N - 9°N, 98°W - 59°W (Ref. 55231)
Western Atlantic: Massachusetts south along U.S. coast, Bermuda, the Bahamas, and throughout the Gulf of Mexico and Caribbean Sea. Records from Brazil are based on misidentifications (Ref. 113893). Records from the eastern Atlantic are vagrants (Ref. 10795).
Length at first maturity / Size / Weight / Age
Maturity: Lm 32.0, range 21 - ? cm
Max length : 89.0 cm TL male/unsexed; (Ref. 55); common length : 40.0 cm TL male/unsexed; (Ref. 55); max. published weight: 20.0 kg (Ref. 4883); max. reported age: 21 years (Ref. 55)
soft rays: 7 - 8. Dorsal profile of head slightly concave, snout long and pointed. Preopercular notch and knob weak. Scale rows on back parallel to lateral line anteriorly, but rising obliquely posteriorly, below soft part of dorsal fin. Young specimens with a dark stripe from snout through the eye to upper opercle and a blue stripe on cheek below eye.
Adults inhabit coastal as well as offshore waters around coral reefs, rocky areas, estuaries, mangrove areas, and sometimes in lower reaches of rivers (especially the young). They are found in fresh water in Florida (Ref. 26938). Often forming large aggregations. Feed mainly at night on small fishes, shrimps, crabs, gastropods, cephalopods and some planktonic items. Easily approached (Ref. 9710). Good food fish (Ref. 9626). Utilized fresh and frozen; eaten pan-fried, broiled, microwaved, and baked (Ref. 9987). Has been reared in captivity (Ref. 35420).
Spawning occurs in summer near the time of the full moon.
