Biology     Glossary (e.g. epibenthic)

Adults inhabit lagoon and seaward reefs. Abundant, in large aggregations over reef tops and upper edges of slopes (Ref. 9710). Usually seen solitary in reefs, staying close to the substrate in depths of about 10 m (Ref. 48636). Diurnal species (Ref. 52881. 120737). Oviparous, distinct pairing during breeding (Ref. 205). Eggs are demersal and adhere to the substrate (Ref. 205). Males guard and aerate the eggs (Ref. 205).

Estimates based on models

Preferred temperature (Ref. 123201): 24.8 - 29.1, mean 27.5 °C (based on 519 cells).
Phylogenetic diversity index (Ref. 82804):  PD50 = 0.5000   [Uniqueness, from 0.5 = low to 2.0 = high].
Bayesian length-weight: a=0.02089 (0.00940 - 0.04644), b=2.98 (2.80 - 3.16), in cm total length, based on LWR estimates for this (Sub)family-body shape (Ref. 93245).
Trophic level (Ref. 69278):  2.7   ±0.30 se; based on food items.
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).
Price category (Ref. 80766):   Unknown.
Nutrients (Ref. 124155):  Calcium = 127 [64, 215] mg/100g; Iron = 0.944 [0.545, 1.610] mg/100g; Protein = 17.9 [16.7, 19.1] %; Omega3 = 0.117 [0.065, 0.206] g/100g; Selenium = 24.8 [11.8, 52.2] μg/100g; VitaminA = 137 [37, 518] μg/100g; Zinc = 1.78 [1.16, 2.66] mg/100g (wet weight);
