Biologia     Glossario (es. epibenthic)

Occurs on lagoon reefs and hovers upside-down among thickets of the staghorn coral Acropora formosa (Ref. 37816, 48637). Often seen resting on underside of coral branches and makes short forays into water column to feed on planktons (Ref 90102).

Estimates based on models

Preferred temperature (Fonte Biblio. 123201): 26.1 - 28.9, mean 27.8 °C (based on 300 cells).
Phylogenetic diversity index (Fonte Biblio. 82804):  PD50 = 0.5000   [Uniqueness, from 0.5 = low to 2.0 = high].
Bayesian length-weight: a=0.00724 (0.00339 - 0.01546), b=3.10 (2.92 - 3.28), in cm total length, based on LWR estimates for this (Sub)family-body shape (Ref. 93245).
Trophic level (Fonte Biblio. 69278):  3.1   ±0.3 se; based on size and trophs of closest relatives
Resilienza (Fonte Biblio. 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 = 289 [94, 921] mg/100g; Iron = 1.64 [0.60, 4.09] mg/100g; Protein = 18.2 [16.0, 20.2] %; Omega3 = 0.172 [0.051, 0.546] g/100g; Selenium = 18.3 [4.4, 61.8] μg/100g; VitaminA = 72.1 [11.2, 447.5] μg/100g; Zinc = 3.11 [1.48, 5.71] mg/100g (wet weight);
