Short description
Identification keys | Morphology | Morphometrics
Dorsal spines (total): 57 - 64; Dorsal soft rays (total): 0; Anal spines: 0; Anal soft rays: 40 - 46; Vertebrae: 62 - 68. Dorsal well notched but joined to caudal; caudal rounded; pectorals bluntly pointed (Ref. 6885). Dark, or with a broken or variegated dark and light patterns usually with dark and light bars accentuating each other across jaw; frequently dark markings near anterior portion of dorsal fin and on the posterior margin of each gill cover; rarely individuals partly or completely bright red (Ref. 6885).
Facultative air-breathing (Ref. 126274); Prefers subtidal areas among rocks (Ref. 2850) and algae to depths of 30 meters (Ref. 51666).
