Biology     Glossary (e.g. epibenthic)

Adults occur solitary or forms small groups on coral outcrops (Ref. 90102). Found in clear water, rich coral habitats on coastal to outer reef crests of slopes to about 15 m depth. They live on rocks and corals on steep slopes. (Ref. 48636). Oviparous. Eggs are demersal and adhesive (Ref. 205), and are attached to the substrate via a filamentous, adhesive pad or pedestal (Ref. 94114). Larvae are planktonic, often found in shallow, coastal waters (Ref. 94114).

Estimates based on models

Preferred temperature (Ref. 123201): 28.4 - 29.2, mean 29 °C (based on 6 cells).
Phylogenetic diversity index (Ref. 82804):  PD50 = 0.5000   [Uniqueness, from 0.5 = low to 2.0 = high].
Bayesian length-weight: a=0.00776 (0.00356 - 0.01695), b=3.00 (2.81 - 3.19), in cm total length, based on LWR estimates for this (Sub)family-body shape (Ref. 93245).
Trophic level (Ref. 69278):  2.0   ±0.00 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). 🛈
