Biology     Glossary (e.g. epibenthic)

Adults inhabit inshore and offshore coral reefs (Ref. 7247). 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): 24.7 - 29.3, mean 27.2 °C (based on 258 cells).
Phylogenetic diversity index (Ref. 82804):  PD50 = 0.5000   [Uniqueness, from 0.5 = low to 2.0 = high].
Bayesian length-weight: a=0.02455 (0.01155 - 0.05216), b=2.98 (2.81 - 3.15), in cm total length, based on LWR estimates for this Genus-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).
Nutrients (Ref. 124155):  Calcium = 109 [55, 167] mg/100g; Iron = 0.758 [0.467, 1.242] mg/100g; Protein = 18.2 [17.0, 19.3] %; Omega3 = 0.119 [0.072, 0.189] g/100g; Selenium = 26.4 [14.8, 48.2] μg/100g; VitaminA = 86.1 [23.5, 292.2] μg/100g; Zinc = 1.75 [1.20, 2.53] mg/100g (wet weight);
