Chaves de identificação | Morfologia | Morfometria
Espinhos dorsais (total) : 53 - 55; Raios dorsais moles (total) : 0; Espinhos anais: 1; Raios anais moles: 37 - 42. Caudal rounded (Ref. 6885). Color variable- males brownish, sometimes with a red tinge; pale spots rimmed with darker on sides of body; spots fainter, smaller, and more numerous dorsally on sides; light on lower part of head with several brown streaks; white on pelvic fins and anterior part of anal fin; other fins with brown pigment spots in bands forming faint bars. Females nearly plain brown on body; in line spread along middle of dorsal fin about 13 dark spots each surrounded by a clear area to form prominent ocelli (Ref. 6885).
Usually in intertidal and subtidal rocky areas (Ref. 2850, 51666). Sometimes hides in crevices and tubeworms holes with only head protruding (Ref. 2850).
