Biology     Glossary (e.g. epibenthic)

Adults are usually seen singly or in small groups on coastal reefs, amongst mixed algae-coral reef or rocky reefs (Ref. 48636). They are found on exposed seaward reefs; less abundant in lagoons and channels. Feed on zooplankton. 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. 113699).

Estimates based on models

Preferred temperature (Ref. 123201): 25 - 29.3, mean 28.5 °C (based on 1936 cells).
Phylogenetic diversity index (Ref. 82804):  PD50 = 0.5000   [Uniqueness, from 0.5 = low to 2.0 = high].
Bayesian length-weight: a=0.01660 (0.00878 - 0.03136), b=2.97 (2.81 - 3.13), in cm total length, based on LWR estimates for this species & (Sub)family-body (Ref. 93245).
Trophic level (Ref. 69278):  3.0   ±0.25 se; based on food items.
Generation time: 3.7 ( na - na) years. Estimated as median ln(3)/K based on 2 growth studies.
Resilience (Ref. 120179):  Medium, minimum population doubling time 1.4 - 4.4 years (Preliminary K or Fecundity.).
Fishing Vulnerability (Ref. 59153):  Low to moderate vulnerability (29 of 100).
Price category (Ref. 80766):   Unknown.
