Description synthétique Morphologie | Morphométrie

Épines dorsales (Total): 3; Rayons mous dorsaux (Total): 25-27; Épines anales 3; Rayons mous anaux: 16; Vertèbres: 26. This species is distinguished by the following set of characters: D III,25-27, usually III,26; A III,16; 16 circumpeduncular scales; 21-27 predorsal scales; horizontal scale rows above anal-fin origin 13-15 + 1 + 3 = 17-19; rounded caudal fin; upper part of pectoral-fin base with a dark spot; anterior part of body with yellow spots or markings (Ref. 89054).

Exclusively found in reefs subject to strong currents and frequent cold-water upwellings; associated with coral overhangs or large rubble pieces on hard bottom substrates. When approached, individuals retreat under the rubble or overhang (Ref. 89054).

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=0.00490 (0.00187 - 0.01281), b=3.11 (2.88 - 3.34), in cm total length, based on LWR estimates for this (Sub)family-body shape (Ref. 93245).

Niveau trophique (Ref. 69278): 3.4 ±0.5 se; based on size and trophs of closest relatives

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