Descrição breve Morfologia | Morfometria

Espinhos dorsais (total): 8; Raios dorsais moles (total): 27-31; Espinhos anais 3; Raios anais moles: 24 - 28. This species is distinguished by the following characters: body deep and compressed, its depth 1.9-2.3 times in standard length or SL; mouth small, teeth numerous (> 30 in jaws of adults), movable, slender and elongate, with expanded incurved tips which are denticulate on the lateral margin (6 denticulations on upper and 4 on lower teeth); total gill rakers on first gill arch 27-36; a continuous unnotched dorsal fin with VIII,27-31; AIII,24-28; caudal fin lunate, concavity 3.7-6 times in SL; a lancet-like spine on caudal peduncle which folds into a deep horizontal groove; colour dark olive to yellowish brown with blue or blue-grey lengthwise lines on body and small orange spots on head and nape; dorsal and anal fins with about 5 lengthwise dark bluish bands; pectoral fins pale with brownish yellow rays; a small blackish spot at rear base of dorsal fin of juveniles and small adults (Ref. 9808).

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 Maturidade | Reprodução | Desova | Ovos | Fecundidade | Larvas

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 and swim around each other discharging milt and eggs, then return to former place and replaced by another group to spawn.
