Biologia     Glossario (es. epibenthic)

Adults inhabit steep outer reef slopes with rich coral growth. They occur singly or in small groups and remains close to shelter, often at the entrance of large caves or near its ceiling (Ref. 48636). Diurnal species (Ref. 54980; 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): 23.4 - 28.3, mean 26.8 °C (based on 317 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):  3.0   ±0.2 se; based on size and trophs of closest relatives
Resilienza (Ref. 120179):  Alto, tempo minimo di raddoppiamento della popolazione meno di 15 mesi (Preliminary K or Fecundity.).
Fishing Vulnerability (Ref. 59153):  Low vulnerability (10 of 100).
Nutrients (Ref. 124155):  Calcium = 148 [70, 246] mg/100g; Iron = 1 [1, 2] mg/100g; Protein = 18.1 [16.8, 19.3] %; Omega3 = 0.142 [0.077, 0.253] g/100g; Selenium = 28.1 [13.2, 58.6] μg/100g; VitaminA = 148 [42, 528] μg/100g; Zinc = 1.72 [1.11, 2.52] mg/100g (wet weight);
