Espinhos dorsais (total) : 9; Raios dorsais moles (total) : 24 - 26; Espinhos anais: 3; Raios anais moles: 22 - 24. Brown in color when preserved; a black bar on upper edge of gill opening; head spotted; a less intense dark mark just behind the eye, connected narrowly with the dark bar; a dark brown region around the caudal spine; outer third of upper pectoral rays pale yellow. Large adults develop a distinctly convex head profile (Ref. 1602). Gill rakers on anterior row:19-23, on posterior row: 21-24.
Inhabits clear outer reef flats and seaward reefs (Ref. 9710). Benthopelagic (Ref. 58302). Solitary or in small wide-ranging groups (Ref. 9710). Usually in schools of mixed similar species when grazing algae (Ref. 48637).
