Short description Morphology | Morphometrics

Dorsal spines (total): 1 - 2; Dorsal soft rays (total): 29-34; Anal spines: 0; Anal soft rays: 26 - 30. Body and head color variable. Blackish to dark bluish branchial blotch extending dorsally to level well above the lower margin of eye and may include ventrally the pectoral fin base and axil. Iris usually dark brown. Orange to red caudal fin soft dorsal and anal fins clear, orange or yellow with spots; pectorals clear. Scale spinulation at midbody closely packed. Male scale ridge rugosities develop at about 80 mm SL developed. Strong first dorsal spine. Large pelvic fin rudiment narrowly attached to posterior margin of ventral flap.

Biology     Glossary (e.g. epibenthic)

Occurs in shallow lagoons and seaward reefs to a depth of about 15 m; common in coral-rich areas. Secretive species (Ref. 9710, 48637) among rocks, sponges or in crevices on the bases of large coral formations. Adults usually form pairs but often only one is observed while the other one is hiding (Ref. 48637).

Estimates of some properties based on models

Preferred temperature (Ref. 115969): 23.7 - 29.2, mean 28.1 (based on 2532 cells).
Phylogenetic diversity index (Ref. 82805):  PD50 = 0.5039   [Uniqueness, from 0.5 = low to 2.0 = high].
Bayesian length-weight: a=0.02138 (0.01227 - 0.03725), b=2.91 (2.75 - 3.07), in cm Total Length, based on LWR estimates for this species & (Sub)family-body (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 to moderate vulnerability (25 of 100) .
