marino demersale. Subtropical; 35°N - 15°N, 98°W - 74°W
Western Atlantic: Florida (USA), Little Bahama Bank (Bahamas) and the entire Gulf of Mexico to Campeche, Mexico (Ref. 7251). Range extended to Brazil (Ref. 94035).
Lunghezza alla prima maturità / Dimensione / Peso / Età
Maturità: Lm 7.6, range 10 - ? cm
Max length : 33.0 cm TL maschio/sesso non determinato; (Ref. 85752)
Dark brown bars on caudal and pectoral fins; bars on pectoral fin irregularly joined (Ref. 26938).
Body shape (shape guide): fusiform / normal.
Commonly found in seagrass beds and rocky cuts in coastal bays and lagoons, and in shallows along open coast. In western coast of Florida, adults spawn in February and March (Ref. 26938). Nesting males produce grunt calls called the boatwhistle as advertisement of competition among males and to attract females (Ref. 45338). Neither opercular nor dorsal gland is venomous (Ref. 57406).
