Biology     Glossary (e.g. epibenthic)

Inhabits clear coastal reefs and protected outer reef habitats with rich invertebrate growth (Ref. 48637). Prefers deeper reefs. Often in pairs (Ref. 9710). Sometimes solitary (Ref. 90102). Secretive, adults are usually in pairs (Ref. 48637).

Estimates of some properties based on models

Phylogenetic diversity index (Ref. 82805):  PD50 = 0.5039   [Uniqueness, from 0.5 = low to 2.0 = high].
Bayesian length-weight: a=0.02089 (0.00983 - 0.04439), b=2.92 (2.74 - 3.10), based on LWR estimates for this (Sub)Family-body shape (Ref. 93245).
Trophic Level (Ref. 69278):  2.9   ±0.4 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 (10 of 100) .
Price category (Ref. 80766):   Unknown.
