Short description Identification keys | Morphology | Morphometrics

Dorsal spines (total): 11 - 12; Dorsal soft rays (total): 11 - 13; Anal spines: 2; Anal soft rays: 12 - 13; Vertebrae: 26. This species is distinguished by the following set of characters: D XI or XII,11-13 (usually XII, 13); A II,12-13 (rarely 13); pectoral rays 15-17 (rarely 17); spiniform caudal rays 2; tubed lateral-line scales 12-14 (usually 13); total gill rakers on first branchial arch 27-31; body depth 1.6-1.8 in SL; colour in life yellowish brown grading to grey brown on posterior body including caudal peduncle; orange bar across pectoral-fin base, invading axil of fin; pelvic fins are yellow; dorsal and anal fins are brown with yellow area posteriorly on each fin; dark brown margin, dorsally and ventrally on caudal fin, tapering in width posteriorly (Ref. 96316).

Biology     Glossary (e.g. epibenthic)

Prefers gentler slopes of coral-rich areas of highly sheltered lagoons and bays, and also on steep outer reef slopes where it can be found in the vicinity of crevices and caverns (Ref. 96316).

Estimates based on models

Preferred temperature (Ref. 123201): 27.2 - 28.8, mean 27.9 °C (based on 32 cells).
Phylogenetic diversity index (Ref. 82804):  PD50 = 0.5000   [Uniqueness, from 0.5 = low to 2.0 = high].
Bayesian length-weight: a=0.02089 (0.00944 - 0.04623), b=2.98 (2.80 - 3.16), in cm total length, based on LWR estimates for this (Sub)family-body shape (Ref. 93245).
Trophic level (Ref. 69278):  3.0   ±0.2 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).
