Biology     Glossary (e.g. epibenthic)

Found on hard substrates of shallow lagoon and seaward reefs from the lower surge zone to a depth of more than 15 m (Ref. 27825 ). Benthopelagic (Ref. 58302 ). Feed on filamentous algae. Form spawning aggregations (Ref. 27825 , 48637 ). Adults usually in small groups, but form large schools in some oceanic locations. Juveniles are often seen in mixed species aggregations (Ref. 48637 ). Species at the bottom of the 'pecking order' among surgeon fishes, and as a result employs the strategy of feeding in large schools that overwhelm the territorial defenses of other herbivores (Ref. 1602 ). Caught with nets (Ref. 30573 ). Can be eaten both raw and cooked (Ref. 7364 ). Maximum depth reported at 25m (Ref. 027115 )
