Biology     Glossary (e.g. epibenthic)

Almost always found in holes of corals. Feed on amphipods and copepods (Ref. 5521). Main diet of benthic harpacticoid copepods (Ref. 94105). Oviparous (Ref. 56066). Eggs are attached to the walls of the parent's shelter and are brooded by the male parent (Ref. 56066).

Estimates based on models

Preferred temperature (Ref. 115969): 27.3 - 28.2, mean 27.9 (based on 226 cells).
Phylogenetic diversity index (Ref. 82805):  PD50 = 0.5000   [Uniqueness, from 0.5 = low to 2.0 = high].
Bayesian length-weight: a=0.00457 (0.00182 - 0.01148), b=3.08 (2.86 - 3.30), in cm Total Length, based on LWR estimates for this (Sub)family-body shape (Ref. 93245).
Trophic level (Ref. 69278):  3.1   ±0.32 se; based on food items.
Resilience (Ref. 69278):  Medium, minimum population doubling time 1.4 - 4.4 years (tmax=4).
Vulnerability (Ref. 59153):  Low vulnerability (21 of 100) .
