Short description

Dorsal spines (total): 9; Dorsal soft rays (total): 10; Anal spines: 3; Anal soft rays: 9. Scales large. 4 median predorsal scales; 2 scale rows on cheek. Caudal fin slightly rounded in initial phase, retained in terminal males with protruding lobes giving a double emarginate effect. Lips cover or nearly cover dental plates. Initial-phase fish without canines; terminal males usually with 1 upper canine and 2 on lower. The initial phase is characterized by a series of irregular dark chevrons which may be difficult to see on dark individuals (Ref. 1602). The basic color may range from a pale gray to a deep mahogany (Ref. 1602). Large initial phase fish develop the dark greenish markings around the lip found in the terminal phase (Ref. 1602).

Inhabits lagoon and seaward reefs from 1 to over 50 m depth. Adults are common in areas with rich coral and high vertical relief (Ref. 9710, 48636). A solitary species (Ref. 90102). Juveniles may school with other species. Form feeding aggregations on rubble and mixed rubble-coral slopes rather than on flats. Females often in schools of mixed species when feeding, males usually seen separate (Ref. 48636). Feeds on benthic algae (Ref. 89972). Males exhibit territorial tendencies.
