Épines dorsales (Total): 8; Rayons mous dorsaux (Total): 24-27; Épines anales 3; Rayons mous anaux: 22 - 25. Prominent black spot at the rear base of dorsal and anal fins; adults with a bluish ring around the eye (Ref 1602). Dorsal and anal fins dark brown. Caudal fin brown in adults, yellow in young.

Biologie     Glossaire (ex. epibenthic)

Inhabits coral and rubble areas of deep lagoon and seaward reefs. Usually solitary, grazing on surface algae (Ref. 90102). Feeds by scooping film of detritus and unicellular algae (e.g. dinoflagellate Gambierdiscus toxicus) that produce ciguatera toxin making this species a key link in the ciguatera food chain (Ref. 1602, 48637). Caught with nets (Ref. 30573).
