Biologia     Glossario (es. epibenthic)

Adults inhabit inshore and offshore coral reefs. They are found in aggregations above corals (Ref. 9710). Benthopelagic (Ref. 58302). 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): 24.9 - 25.6, mean 25.3 °C (based on 35 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).
Price category (Ref. 80766):   Unknown.
Nutrients (Ref. 124155):  Calcium = 161 [75, 275] mg/100g; Iron = 1.01 [0.57, 1.75] mg/100g; Protein = 18 [17, 19] %; Omega3 = 0.137 [0.074, 0.249] g/100g; Selenium = 24 [11, 51] μg/100g; VitaminA = 176 [49, 626] μg/100g; Zinc = 1.83 [1.17, 2.72] mg/100g (wet weight);
