Biology     Glossary (e.g. epibenthic)

Adults inhabit outer coral or rocky reefs. They usually form large aggregations in shallow waters e.g. in lagoons; feeding well above the bottom on zooplankton (Ref. 2334). 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. 115969): 24.5 - 28.3, mean 27 (based on 208 cells).
Phylogenetic diversity index (Ref. 82805):  PD50 = 0.5000   [Uniqueness, from 0.5 = low to 2.0 = high].
Bayesian length-weight: a=0.02630 (0.01530 - 0.04521), b=3.06 (2.92 - 3.20), in cm Total Length, based on LWR estimates for this species & Genus-body shape (Ref. 93245).
Trophic Level (Ref. 69278):  3.0   ±0.09 se; Based on food items.
Generation time: 1.4 ( na - na) years. Estimated as median LN(3)/K based on 1 growth studies.
Resilience (Ref. 120179):  High, minimum population doubling time less than 15 months (K=0.8).
Vulnerability (Ref. 59153):  Low vulnerability (17 of 100) .
