Kurzbeschreibung Bestimmungsschlüssel | Morphologie | Morphometrie

Rückenflossenstacheln (insgesamt) : 8; Rückenflossenweichstrahlen (insgesamt) : 27 - 31; Afterflossenstacheln: 3; Afterflossenweichstrahlen: 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).
Body shape (shape guide): short and / or deep; Cross section: compressed.

Biologie     Fachlexikon (Englisch) (z.B. 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.

Lebenszyklus und Paarungsverhalten Geschlechtsreife | Fortpflanzung | Ablaichen | Eier | Fruchtbarkeit | Larven

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.
