Short description Identification keys | Morphology | Morphometrics

Dorsal spines (total): 0; Dorsal soft rays (total): 11 - 13; Anal spines: 0; Anal soft rays: 10 - 12. Adults brown to grey with blotches and clusters of black spots on back and sides; pelagic juveniles covered with black spots (Ref. 4423).

Biology     Glossary (e.g. epibenthic)

Inhabit clear protected reefs with sponge and algal habitats. Often in large sponges during the day (Ref. 48637). Usually over sand and mud bottoms to at least 170 m (Ref. 30573). Occasionally on reefs (Ref. 9680). Active at night, feeding among reefs (Ref. 48637). A nocturnal species (Ref. 9710) that presumably feeds on hard-shelled invertebrates (Ref. 9680, 48637).

Estimates based on models

Preferred temperature (Ref. 123201): 22.3 - 28.3, mean 26.8 °C (based on 908 cells).
Phylogenetic diversity index (Ref. 82804):  PD50 = 0.6250   [Uniqueness, from 0.5 = low to 2.0 = high].
Bayesian length-weight: a=0.04677 (0.01905 - 0.11483), b=2.82 (2.61 - 3.03), in cm total length, based on LWR estimates for this (Sub)family-body shape (Ref. 93245).
Trophic level (Ref. 69278):  3.6   ±0.59 se; based on food items.
Resilience (Ref. 120179):  High, minimum population doubling time less than 15 months (Preliminary K or Fecundity.).
Fishing Vulnerability (Ref. 59153):  Low vulnerability (20 of 100).
Price category (Ref. 80766):   Unknown.
