Short description

Dorsal spines (total): 6; Dorsal soft rays (total): 27 - 29; Anal spines: 2; Anal soft rays: 27 - 30. Adults bluish grey to olivaceous brown in color, commonly pale anteriorly and on cheek and throat; short irregular lines on sides of body; diagonal lines on horn; lip edges blue (Ref. 3145). Subadults with dark spots on head and body (Ref. 3145). Juveniles lack the prominent horn of adults (Ref. 1602).

Inhabit mid-waters along steep outer lagoon and seaward reef drop-offs. Also found along rocky shores (Ref. 30573, 48637). Benthopelagic (Ref. 58302). Usually in small groups but form large schools in oceanic locations or on reefs subject to strong currents (Ref. 48637). Juveniles and subadults feed on benthic algae; adults feed on zooplankton.
