Biology     Glossary (e.g. epibenthic)

A common species found in coral and rocky reefs areas exposed to ocean swells (Ref. 9710). Adults form loose groups near the bottom (Ref. 9710). 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. 54980; 113699).

Estimates based on models

Preferred temperature (Ref. 123201): 25.9 - 27.8, mean 26.6 °C (based on 236 cells).
Phylogenetic diversity index (Ref. 82804):  PD50 = 0.5625   [Uniqueness, from 0.5 = low to 2.0 = high].
Bayesian length-weight: a=0.01479 (0.00651 - 0.03363), b=3.00 (2.81 - 3.19), in cm total length, based on LWR estimates for this (Sub)family-body shape (Ref. 93245).
Trophic level (Ref. 69278):  3.0   ±0.1 se; based on diet studies.
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 = 165 [91, 300] mg/100g; Iron = 0.962 [0.591, 1.533] mg/100g; Protein = 18.6 [17.5, 19.6] %; Omega3 = 0.168 [0.098, 0.275] g/100g; Selenium = 20.4 [11.0, 38.2] μg/100g; VitaminA = 174 [58, 502] μg/100g; Zinc = 2.41 [1.65, 3.38] mg/100g (wet weight);
