Biology     Glossary (e.g. epibenthic)

Adults are found in lagoon and seaward reefs, aggregate in caves, often upside down. Males incubate the eggs mass in their mouth (Ref. 9710). Minimum depth reported from Ref. 27115.

Estimates of some properties based on models

Preferred temperature (Ref. 115969): 24.6 - 28.7, mean 26.8 (based on 572 cells).
Phylogenetic diversity index (Ref. 82805):  PD50 = 0.6250   [Uniqueness, from 0.5 = low to 2.0 = high].
Bayesian length-weight: a=0.01096 (0.00441 - 0.02728), b=2.98 (2.76 - 3.20), in cm Total Length, based on LWR estimates for this (Sub)family-body shape (Ref. 93245).
Trophic Level (Ref. 69278):  3.4   ±0.2 se; Based on size and trophs of closest relatives
Resilience (Ref. 69278):  High, minimum population doubling time less than 15 months (Preliminary K or Fecundity.).
Vulnerability (Ref. 59153):  Low vulnerability (12 of 100) .
