; marino associati a barriera corallina; distribuzione batimetrica 1 - 80 m (Ref. 5217). Subtropical; 42°N - 35°S, 98°W - 28°W
Western Atlantic: North Carolina, USA, the northern Gulf of Mexico and the Bahamas southward to Uruguay. Occurrence in western Caribbean is doubtful (Ref. 26938).
Length at first maturity / Size / Peso / Age
Maturity: Lm 12.9  range ? - ? cm
Max length : 30.0 cm TL maschio/sesso non determinato; (Ref. 7251); common length : 16.0 cm TL maschio/sesso non determinato; (Ref. 5217)
Spine dorsali (totale): 10; Raggi dorsali molli (totale): 12; Spine anali 3; Raggi anali molli: 7 - 8. Body pale brown dorsally with several vertical dark brown bars, becoming white ventrally; dorsal fin dusky with longitudinal yellow lines; pectoral, pelvic and anal fins dusky; caudal fin dusky with small yellow blotches (Ref. 13608). Preopercle has spines radiating from 2 centers (Ref. 26938).
Inhabits bays, coastal grassy areas and shallow banks. Solitary (Ref. 26340) and retreats into shelter when frightened (Ref. 9710). Neither opercular spine nor anterolateral glandular grooves with venom gland is present (Ref. 57406). Synchronously hermaphroditic. Popular as a pan fish despite its small size.
