Biology     Glossary (e.g. epibenthic)

Adults inhabit coral rich areas of outer reef passes and slopes. They occur singly or in small groups near the bottom (Ref. 7247). Diurnal species (Ref. 113699). 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): 25.6 - 28.8, mean 27.6 °C (based on 290 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):  2.6   ±0.29 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 = 128 [63, 197] mg/100g; Iron = 0.823 [0.499, 1.372] mg/100g; Protein = 18.1 [16.9, 19.2] %; Omega3 = 0.121 [0.071, 0.198] g/100g; Selenium = 26.1 [14.1, 48.8] μg/100g; VitaminA = 88.5 [23.4, 306.7] μg/100g; Zinc = 1.93 [1.31, 2.80] mg/100g (wet weight);
