Biology     Glossary (e.g. epibenthic)

Inhabits virtually all coral reef zones (Ref. 1602). Benthopelagic in or near crevices and holes (Ref. 58302). Common in thickets of staghorn Acropora or in large Pocillopora heads (Ref. 1602). Feeds on small crustaceans, worms, and fishes during the night (Ref. 30874). Spine of preopercle venomous. Minimum depth reported taken from Ref. 128797.

Estimates based on models

Preferred temperature (Ref. 123201): 24.9 - 29, mean 27.8 °C (based on 1198 cells).
Phylogenetic diversity index (Ref. 82804):  PD50 = 0.5000   [Uniqueness, from 0.5 = low to 2.0 = high].
Bayesian length-weight: a=0.01622 (0.00970 - 0.02713), b=3.13 (2.99 - 3.27), in cm total length, based on LWR estimates for this species & Genus-body shape (Ref. 93245).
