Description synthétique Morphologie | Morphométrie

Épines dorsales (Total): 8; Rayons mous dorsaux (Total): 27-31; Épines anales 3; Rayons mous anaux: 24 - 28. Body dark olive-brown. Orange spots on head. Pectoral fin yellowish, caudal and ventral fins brown, anterior part of caudal fin pale. Each side of caudal peduncle with sharp, forward-pointing erectile spine which folds down into a horizontal groove. Scales minute. Juveniles with 8 - 12 pale stipes inclining downward and backwards on body. Teeth movable, slender, tips incurved and expanded; upper jaw 5-6 denticulations, lower only 3-4. Gill rakers 27-36 in anterior row, 29-42 in posterior row.

Biologie     Glossaire (ex. epibenthic)

Inhabits reef flats and lagoon and seaward reefs to a depth of over 30 m. Occurs over coral (Ref. 58534), rock, pavement, or rubble substrates. May occur singly or in small to very large, often mixed-species aggregations (Ref. 48637). Feeds on surface film of blue-green algae and diatoms (making this species a key link in the ciguatera food chain) as well as on various small invertebrates.

Life cycle and mating behavior Maturité | Reproduction | Frai | Œufs | Fécondité | Larves

In Tahiti, spawning starts near full moon with the formation of schools of several thousand fish at various depths. The fish remain almost motionless for between 1 to 3 hrs, then change their normal color to pale grey. About 4 or 5 fishes rise a few yards above main school & swim around each other discharging milt & eggs, then return to former place & replaced by another group to spawn.
