Biology     Glossary (e.g. epibenthic)

Adults inhabit coral or rocky reefs (Ref. 9334). They aggregate in large numbers in open water above reefs and feed on zooplankton. Not strongly territorial as other damselfishes in the area. They become almost invisible in the darkness of deep water except for its brilliant post-dorsal white spot which gives the illusion of glowing in the dark. 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): 21.2 - 28.5, mean 25.9 °C (based on 40 cells).
Phylogenetic diversity index (Ref. 82804):  PD50 = 0.5000   [Uniqueness, from 0.5 = low to 2.0 = high].
Bayesian length-weight: a=0.01288 (0.00716 - 0.02316), b=3.10 (2.94 - 3.26), in cm total length, based on LWR estimates for this species & (Sub)family-body (Ref. 93245).
Trophic level (Ref. 69278):  3.4   ±0.45 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 = 88.8 [53.6, 148.6] mg/100g; Iron = 0.813 [0.525, 1.261] mg/100g; Protein = 18.7 [17.6, 19.6] %; Omega3 = 0.169 [0.108, 0.262] g/100g; Selenium = 26.7 [15.3, 48.6] μg/100g; VitaminA = 213 [79, 552] μg/100g; Zinc = 1.53 [1.07, 2.08] mg/100g (wet weight);
