Environment / Climate / Range
Marine; freshwater; brackish; reef-associated; oceano-estuarine (Ref. 4233); depth range 0 - 140 m (Ref. 36484), usually 0 - 20 m (Ref. 40849). Subtropical; 41°N - 23°S
Length at first maturity / Size / Weight / Age
Maturity: Lm 37.0, range 34 - ? cm
Max length : 101 cm FL male/unsexed; (Ref. 40637); common length : 60.0 cm TL male/unsexed; (Ref. 5217); max. published weight: 13.4 kg (Ref. 40637)

soft rays: 16 - 17. No spots on pectoral fins, and the spot posteriorly on the gill cover is small or absent; the scutes tend to be dusky or blackish; caudal fin is yellow. The young have broad blackish bars on the body.
Western Atlantic: New Jersey (USA), Bermuda, and northern Gulf of Mexico to São Paulo, Brazil (Ref. 57756). Eastern Atlantic: St. Paul's Rocks (Ref. 13121), Ascension Island, and two confirmed records from the Gulf of Guinea (Ref. 7097).
A pelagic (Ref. 26340) schooling species usually found in offshore reefs (Ref. 9710). Juveniles are encountered along shores of sandy beaches, also over muddy bottoms (Ref. 9626). May penetrate into brackish water and ascend rivers. Feed on fishes, shrimps, and other invertebrates (Ref. 3277). Often approach divers (Ref. 9710). Eggs are pelagic (Ref. 4233).
