Short description Morphology | Morphometrics

Dorsal spines (total): 0; Dorsal soft rays (total): 9-10; Anal spines: 0; Anal soft rays: 9 - 10. Many white spots scattered on body (Ref. 559).

Biology     Glossary (e.g. epibenthic)

Occurs in clear lagoon and seaward reefs, Ref. 48637. Found with sponges at various depths (Ref. 48637). Prefers sheltered areas in the form of holes in dead and living corals. Solitary or paired. Feeds on sponges, polychaetes, filamentous algae and on smaller quantities of tunicates, crustaceans, echinoderms and corals.

Estimates of some properties based on models

Phylogenetic diversity index (Ref. 82805):  PD50 = 0.5000   [Uniqueness, from 0.5 = low to 2.0 = high].
Bayesian length-weight: a=0.02818 (0.01190 - 0.06674), b=2.94 (2.73 - 3.15), 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):  High, minimum population doubling time less than 15 months (Preliminary K or Fecundity.).
Vulnerability (Ref. 59153):  Low vulnerability (10 of 100) .
