Biology     Glossary (e.g. epibenthic)

Inhabits among rubble or live corals of seaward reefs (Ref. 1602), usually in caves and crevices with rich invertebrate growth to at least 40 m depth (Ref. 48636). Benthopelagic (Ref. 58302). Feeds mainly on benthic crustaceans, but also takes small mollusks, echinoids (sea urchins) (Ref. 1602), fish eggs, and crab larvae (Ref. 37816).

Estimates of some properties based on empirical models

Phylogenetic diversity index (Ref. 82805):  PD50 = 0.5078   [Uniqueness, from 0.5 = low to 2.0 = high].
Bayesian length-weight: a=0.01061 (-0.15153 - 0.17274), b=3.04 (2.95 - 3.13), based on LWR estimates for this family-BS (Ref. 93245).
Trophic Level (Ref. 69278):  3.4   ±0.39 se; Based on food items.
Resilience (Ref. 69278):  High, minimum population doubling time less than 15 months (Preliminary K or Fecundity.).
Vulnerability (Ref. 59153):  Low to moderate vulnerability (29 of 100) .
Price category (Ref. 80766):   Very high.
