Remark: Sister species: <i>Acanthurus bahianus</i> (Ref. 087362).
Comments: Inhabits shallow bottoms with coral or rocky formations (Ref. 13628); also found around inshore rocky areas with patches of sand, feeding primarily on benthic algae and occasionally grazing on seagrass beds (Ref. 87362).  Usually occurs in groups of five or more individuals.  Mainly diurnal species. The spine on both sides of the caudal peduncle may inflict painful wounds (Ref. 5217).  Marketed fresh.  Minimum depth reported from Ref. 27115.  Previously reported longevity of 31 years from Ref. 52229 refers to <i>Acanthurus bahianus</i>, a case of misidentification.
