Duri punggung (Keseluruhan (total)) : 13; duri punggung lunak (Keseluruhan (total)) : 15; Duri dubur: 3; Sirip dubur lunak: 12. Bluish grey with blackish margin on gill cover; diagnostic white patch just in front of each eye (Ref. 11482).
Usually seen in aggregations while grazing over shallow reefs (Ref. 11482). May also mix with schools of other species (Ref. 5227).The fine mat of comb-like, bicuspid and tricuspid teeth are used to scrape algae from rocks and corals (Ref. 28023).
