Western Atlantic: Canada (Ref. 5951) to Maine to Florida, USA (possibly from Nova Scotia, Canada), along coasts of central and south America (Ref. 26938) to Uruguay, including Bermuda and Gulf of Mexico (Ref. 9626). Rare in Greater Antilles (Ref. 26938).
Size / Weight / Age
Maturity: Lm ?  range ? - ? cm
Max length : 48.3 cm TL male/unsexed; (Ref. 9626); common length : 35.0 cm TL male/unsexed; (Ref. 5217); max. published weight: 2.1 kg (Ref. 40637)
Adults are found in shallow coastal waters, usually over hard or sandy bottoms. Juveniles may be encountered in estuarine areas (Ref. 9626) and off sandy beaches (Ref. 5217). Found in schools, but may be encountered in small groups or in pairs (Ref. 26235). Adults feed on small crabs, shrimps, fishes, and worms. Flesh has excellent flavor (Ref. 5521). Marketed fresh (Ref. 9710).
