Maturity: Lm 7.6, range 10 - ? cm
Max length : 33.0 cm TL hane/ej könsbestämd; (Ref. 85752)
Dark brown bars on caudal and pectoral fins; bars on pectoral fin irregularly joined (Ref. 26938).
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).
