Short description Identification keys | Morphology | Morphometrics

Dorsal spines (total): 12; Dorsal soft rays (total): 13; Anal spines: 3; Anal soft rays: 9 - 10. 6 straight, even, and nearly equally wide bronze-yellow stripes on side (Ref. 26938). Snout short, mouth nearly horizontal and small, the maxilla usually not reaching a vertical at front edge of pupil; fins largely yellow (Ref. 13442).

Biology     Glossary (e.g. epibenthic)

Inhabits exposed rocky areas and coral reefs. Often near elkhorn and staghorn corals (Ref. 9710). Commonly found in schools. Juveniles are encountered in Thalassia beds (Ref. 9626). Adults are observed in coral reefs during the day but enters open waters at night to feed on mainly on plankton (Ref. 9626), but also on small crustaceans and mollusks. Marketed fresh (Ref. 3798).

Life cycle and mating behavior Maturity | Reproduction | Spawning | Eggs | Fecundity | Larvae

Estimates based on models

Preferred temperature (Ref. 123201): 26.3 - 28.2, mean 27.4 °C (based on 634 cells).
Phylogenetic diversity index (Ref. 82804):  PD50 = 0.5000   [Uniqueness, from 0.5 = low to 2.0 = high].
Bayesian length-weight: a=0.01202 (0.00732 - 0.01975), b=3.00 (2.86 - 3.14), in cm total length, based on LWR estimates for this species & (Sub)family-body (Ref. 93245).
Trophic level (Ref. 69278):  3.5   ±0.2 se; based on diet studies.
Resilience (Ref. 120179):  High, minimum population doubling time less than 15 months (Preliminary K or Fecundity.).
