Biology     Glossary (e.g. epibenthic)

Adults inhabit coral-rich areas of clear lagoon and seaward reefs. They occur singly or in small groups and remains close to thickly branching coral shelter (Ref. 9710). 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). Diurnal species (Ref. 54980; 113699).

Estimates based on models

Preferred temperature (Ref. 115969): 25.4 - 28.9, mean 27.7 (based on 396 cells).
Phylogenetic diversity index (Ref. 82804):  PD50 = 0.5000   [Uniqueness, from 0.5 = low to 2.0 = high].
Bayesian length-weight: a=0.01514 (0.00729 - 0.03144), b=2.92 (2.74 - 3.10), in cm Total Length, based on LWR estimates for this species & (Sub)family-body (Ref. 93245).
Trophic level (Ref. 69278):  2.7   ±0.29 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).
