Short description Identification keys | Morphology | Morphometrics

Dorsal spines (total): 7; Dorsal soft rays (total): 8 - 9; Anal spines: 1; Anal soft rays: 8 - 9. This species is characterized by the following characters: scales on the cheek, opercle, pectoral fin base and the predorsal midline; a moderate to well developed interorbital trench with steep sides; absence of postorbital trenches; no enlarged teeth in the upper jaw; ground color of preserved specimens yellow with a strikingly black caudal fin, in freshly dead material the ground color is mustard-yellow and the caudal fin rays are deep red with black interradial membranes, edged with a white band (Ref. 59339).

Inhabits outer reef slopes, often on rubble, rock and sand bottoms in 6-20 m (Ref. 90102).

Estimates based on models

Preferred temperature (Ref. 123201): 28.6 - 29.3, mean 28.9 °C (based on 464 cells).

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).
