Short description Identification keys | Morphology | Morphometrics

Dorsal spines (total): 7; Dorsal soft rays (total): 7 - 8; Anal spines: 1; Anal soft rays: 8 - 9. Diagnosis: frontal ridge behind the orbits slopes steeply into a wide interorbital trench anteromedially, and into postorbital trenches laterally; posterior nasal opening separate from anterior margin of eye; elongate first dorsal spines absent; fifth pelvic fin ray branched once dichotomously; body red-orange with four white dorsolateral spots between caudal region and origin of second dorsal; no white ventrolateral spots; facial pattern with two thin, diffuse white diagonal lines under orbit and one over preopercle (Ref. 57688).

Inhabits clear lagoon and seaward reefs; within crevices and caves of mostly dead coral rock and sandy rubble bottom (Ref. 9710, 57688). Solitary (Ref. 90102).

Estimates based on models

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

Bayesian length-weight: a=0.01023 (0.00477 - 0.02194), b=3.02 (2.84 - 3.20), in cm Total Length, based on LWR estimates for this (Sub)family-body shape (Ref. 93245).

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).
