Short description Identification keys | Morphology | Morphometrics

Dorsal spines (total): 9; Dorsal soft rays (total): 11; Anal spines: 3; Anal soft rays: 12. With a large blue-margined black patch covering the posteriodorsal region of the head and the dorsal anterior third of the body, an orange submarginal line along the length of the dorsal fin, and upper and lower rays of the caudal fin forming dark lobes that protrude beyond the medial caudal margin (Ref. 35870).

Mainly in open ground areas covered with rubble; may also be found in areas with rock and coral patches (Ref. 35870). Found in small harems and feeds on material on the substratum (Ref. 35870). Minimum depth reported from Ref. 35870.

Estimates based on models

Preferred temperature (Ref. 115969): 24.8 - 28.8, mean 27.5 (based on 216 cells).

Phylogenetic diversity index (Ref. 82804): PD₅₀ = 0.5000 [Uniqueness, from 0.5 = low to 2.0 = high].

Bayesian length-weight: a=0.00977 (0.00470 - 0.02030), b=3.07 (2.89 - 3.25), in cm Total Length, based on LWR estimates for this (Sub)family-body shape (Ref. 93245).

Trophic level (Ref. 69278): 3.4 ±0.4 se; based on size and trophs of closest relatives

Resilience (Ref. 120179): High, minimum population doubling time less than 15 months (Preliminary K or Fecundity.).

Fishing Vulnerability (Ref. 59153): Low vulnerability (10 of 100).
