Espinas dorsales (total) : 10; Radios blandos dorsales (total) : 12; Espinas anales: 3; Radios blandos anales: 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).
Body shape (shape guide): fusiform / normal.
Inhabits bays, coastal grassy areas and shallow banks. Solitary (Ref. 26340) and retreats into shelter when frightened (Ref. 9710).
