Etymology: Trachinotus: Greek, trachys, -eia, -ys = rough + Greek,noton = back (Ref. 45335).
Environment: milieu / climate zone / depth range / distribution range
Marine; reef-associated; depth range 0 - 12 m (Ref. 9710). Subtropical; 43°N - 37°S
Western Atlantic: Massachusetts (USA), Bermuda, and the Gulf of Mexico to Argentina.
Size / Weight / Age
Maturity: Lm ?  range ? - ? cm
Max length : 50.0 cm TL male/unsexed; (Ref. 7251); common length : 35.0 cm TL male/unsexed; (Ref. 5217); max. published weight: 560.00 g (Ref. 40637)
Adults form schools in clear coastal areas, usually near coral formations (Ref. 5217). Juveniles common in clean sandy beaches (Ref. 5217). Adults feed on crustaceans, polychaete worms, insect pupae, mollusks and fishes (Ref. 9626). Between 1995 and 2000, at least 2 specimens were traded as aquarium fish at Fortaleza, Ceará (Ref. 49392).
