Biology     Glossary (e.g. epibenthic)

Adults inhabit outer reef slopes and deep lagoons (Ref. 9710). They form small to moderate aggregations on reef crests with moderate currents (Ref. 48636). 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). Diurnal species (Ref. 52881).

Estimates based on models

Preferred temperature (Ref. 123201): 24.5 - 29, mean 27.9 °C (based on 668 cells).
Phylogenetic diversity index (Ref. 82804):  PD50 = 0.5000   [Uniqueness, from 0.5 = low to 2.0 = high].
Bayesian length-weight: a=0.01259 (0.00571 - 0.02773), b=3.03 (2.84 - 3.22), in cm total length, based on LWR estimates for this (Sub)family-body shape (Ref. 93245).
Trophic level (Ref. 69278):  2.7   ±0.31 se; based on food items.
Resilience (Ref. 120179):  Medium, minimum population doubling time 1.4 - 4.4 years (Preliminary K or Fecundity.).
Fishing Vulnerability (Ref. 59153):  Low vulnerability (10 of 100).
Nutrients (Ref. 124155):  Calcium = 83.8 [48.9, 124.1] mg/100g ; Iron = 0.709 [0.463, 1.061] mg/100g ; Protein = 18.6 [17.6, 19.6] % ; Omega3 = 0.142 [0.097, 0.206] g/100g ; Selenium = 26.1 [16.2, 44.2] μg/100g ; VitaminA = 113 [40, 313] μg/100g ; Zinc = 1.8 [1.3, 2.4] mg/100g (wet weight);
