Épines dorsales (Total) : 16 - 18; Rayons mous dorsaux (Total) : 9 - 11; Épines anales: 1; Rayons mous anaux: 19 - 21. Dorsal fin: III, XIII-XV (modally XIV), 9-11 (typically10). Anal fin: I, 19-21 (rarely 19). Lateral line with 17-20 (typically 18) pored scales and 16-20 (typically 18) notched scales. Pattern of mandibular pore 4+1+4. Lobate supraorbital cirrus. Nasal cirrus bearing forked tips. First dorsal fin higher or same height as second dorsal fin. Female body coloration white with 4-5 brownish-red H-bars; males black with 2 white bars below junction of 2nd and 3rd dorsal fin with caudal peduncle. Caudal-fin rays bearing alternating white and reddish-brown marks. Supraoccipital sensory canal forming a flattened curve anterior to 1st dorsal fin.
Body shape (shape guide): elongated; Cross section: oval.
Adults inhabit rocky shores. They feed on algae (Ref. 9137). Eggs are hemispherical and covered with numerous sticky threads that anchor them in the algae on the nesting sites (Ref. 240). Larvae are planktonic which occur primarily in shallow, nearshore waters (Ref. 94114).
