背棘 (總數) : 9 - 10; 背的軟條 (總數) : 19 - 22; 臀鰭軟條: 25 - 29; 脊椎骨: 35 - 40. This species is distinguished by the following characters: D 9-10 (mode 9) spines; 20-24 (mode 21) scales below lateral line; posterior end of dorsal-fin base before the anal-fin base; body coppery-red when fresh; anterior suborbital area with dark rounded marking margined with white lines, or broad dark inverse trapezoid marking; preopercle with dark spot at posteroventral corner, dark line along posterior margin; spinous portion of dorsal fin often with longitudinal black stripe on lower half; faint longitudinal dark line along anal-fin base; pelvic-fin base lacking a distinct black spot anteriorly (Ref. 76763).
Adults inhabit rocky shores among Sargassum (Ref. 76763). Viviparous, female carries the developing young (Ref. 205).
