Brown in color when preserved; with or without fine bluish gray longitudinal lines on body; pale pectoral fins with upper edge narrowly black; pelvic fins 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 spine encircled with a narrow black margin. Gill rakers on anterior row:20-24; on posterior row:18-23.
Found on hard substrates of shallow lagoon and seaward reefs from the lower surge zone to a depth of more than 15 m (Ref. 27825). Benthopelagic (Ref. 58302). Feed on filamentous algae. Form spawning aggregations (Ref. 27825, 48637). Adults usually in small groups, but form large schools in some oceanic locations. Juveniles are often seen in mixed species aggregations (Ref. 48637). Species at the bottom of the 'pecking order' among surgeon fishes, and as a result employs the strategy of feeding in large schools that overwhelm the territorial defenses of other herbivores (Ref. 1602). Caught with nets (Ref. 30573). Can be eaten both raw and cooked (Ref. 7364). Maximum depth reported at 25m (Ref. 027115)
Form spawning aggregations (Ref. 27825).
