Short description Identification keys | Morphology | Morphometrics

Dorsal spines (total): 4 - 7; Dorsal soft rays (total): 8 - 10; Anal spines: 1; Anal soft rays: 9 - 12. Premaxilla with long ascending process and two lateral processes. Gill rakers 22-25. Midlateral scale count 38-42.

Biology     Glossary (e.g. epibenthic)

Relatively common in both high island and atoll lagoons (Ref. 1602). They are not found in the rougher waters over reefs and are attracted to light at night in lagoons (Ref. 9760). Used as bait in the tuna fishery (Ref. 6822).

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

Oviparous, distinct pairing during breeding (Ref. 205).

Estimates based on models

Preferred temperature (Ref. 123201): 26.9 - 29.3, mean 28.8 °C (based on 1498 cells).
Phylogenetic diversity index (Ref. 82804):  PD50 = 0.5001   [Uniqueness, from 0.5 = low to 2.0 = high].
Bayesian length-weight: a=0.00437 (0.00217 - 0.00879), b=3.15 (2.97 - 3.33), in cm total length, based on LWR estimates for this species & (Sub)family-body (Ref. 93245).
Trophic level (Ref. 69278):  3.3   ±0.4 se; based on size and trophs of closest relatives
Resilience (Ref. 120179):  High, minimum population doubling time less than 15 months (Preliminary K or Fecundity.).
Fishing Vulnerability (Ref. 59153):  Low vulnerability (10 of 100).
Nutrients (Ref. 124155):  Calcium = 143 [75, 286] mg/100g; Iron = 0.761 [0.418, 1.395] mg/100g; Protein = 19.4 [17.1, 21.8] %; Omega3 = 0.129 [0.056, 0.336] g/100g; Selenium = 15.1 [6.5, 37.2] μg/100g; VitaminA = 228 [65, 714] μg/100g; Zinc = 2.1 [1.4, 3.1] mg/100g (wet weight);
