Biology     Glossary (e.g. epibenthic)

Found in aggregations over hard, algal coated bottoms of exposed, surf-swept outer reef flats, lagoon and seaward reefs, to a depth of at least 24 m (Ref. 30573). Benthopelagic (Ref. 58302). Juveniles associated with floating material (Ref. 58302). Mainly herbivorous, feeding on seaweed and associated invertebrates (Ref. 30573). Appear to be more commonly involved in hallucinogenic fish poisoning than most other related species (Ref. 4690). Caught with other types of artisanal gear. Minimum depth reported taken from Ref. 128797.
