Biology     Glossary (e.g. epibenthic)

Occur in lagoon, seaward reefs (Ref. 1602) and sheltered inner reef slopes (Ref. 48637). Juveniles often associated with isolated patches of branching coral or rubble of shallow sandy protected areas. Adults occur singly or in pairs on the slopes of deep lagoon or seaward reefs (Ref. 37816, 48637). Often hostile towards divers and may attack unprovoked when caring for eggs (Ref. 48637). Feed on sea urchins, coral, crabs and other crustaceans, mollusks and tube worms. Oviparous (Ref. 205). Largest triggerfish; females are reported to have attacked divers when guarding their nest (Ref. 2334). Also caught with drive-in nets. Marketed fresh and dried-salted (Ref. 9770).
