Biology     Glossary (e.g. epibenthic)

Adults inhabit shallow reefs, both in lagoons and outer reef areas. They frequently move in groups. Juveniles found between soft corals in lagoons at depths of up to 2 m (Ref. 9710, 48637). Adults in groups, often mixed with other similar species (Ref. 48637).

Estimates based on models

Preferred temperature (Ref. 123201): 25.6 - 29.3, mean 28.5 °C (based on 2408 cells).
Phylogenetic diversity index (Ref. 82804):  PD50 = 0.5000   [Uniqueness, from 0.5 = low to 2.0 = high].
Bayesian length-weight: a=0.02344 (0.01118 - 0.04914), b=2.95 (2.78 - 3.12), in cm total length, based on LWR estimates for this Genus-body shape (Ref. 93245).
Trophic level (Ref. 69278):  2.0   ±0.1 se; based on size and trophs of closest relatives
Generation time: 1.6 ( na - na) years. Estimated as median ln(3)/K based on 1 growth studies.
Resilience (Ref. 120179):  Low, minimum population doubling time 4.5 - 14 years (tmax=30; K=0.67).
Fishing Vulnerability (Ref. 59153):  Low to moderate vulnerability (26 of 100).
Price category (Ref. 80766):   Medium.
Nutrients (Ref. 124155):  Calcium = 57.6 [23.7, 169.7] mg/100g; Iron = 0.797 [0.301, 1.988] mg/100g; Protein = 18.4 [17.1, 19.6] %; Omega3 = 0.0927 [, ] g/100g; Selenium = 19 [7, 57] μg/100g; VitaminA = 26.1 [6.0, 106.8] μg/100g; Zinc = 2.6 [0.8, 4.9] mg/100g (wet weight);
