Dorsal-fin rays IX, 24-27 ; anal-fin rays III, 22-24 ; pectoral-fin rays 16-17. Body brown; with or without fine bluish gray longitudinal lines; pale pectoral fins with upper edge narrowly black; pelvics brown. Lips blackish brown; median upper teeth tend to be pointed. Dorsal fin base with a prominent black spot larger than 1/2 eye diameter; a smaller spot on base of anal fin. Groove of caudal peduncle spine encircled with a narrow black margin. Gill rakers on upper limb girst gill arch:20-24; on lower limb:18-23.
Generally found on shallow coral reefs or rocky bottom from the lower surge zone to a depth of more than 15 m. Feed on filamentous algae. Form spawning aggregations. A species at the bottom of the 'pecking order' among surgeon fishes, and as a result empl
