Short description Morphology | Morphometrics

This species is distinguished by the following set of characters: scale rows between 6th dorsal-fin spine and lateral line 6-7 (usually 7); scale rows between last dorsal-fin spine and lateral line 6-7 (7); middle postorbital scale rows 2-3 (3); caudal-peduncle depth 7.2-9.0% (modally 8.1%) of SL; interorbital width at vertical midline of eye 17.9-21.4 % (19.5%) of HL; maxillary depth 14.3-16.3% (15.7%) of HL; lower opercular spine length 25.0-28.9% (27.0%) of HL; dorsal margin of interorbital space flat; presence of nasal and parietal spines; supraocular spine rudimentary; second lacrimal spine directed anteroventrally or ventrally (directed posteroventrally only on left side of CSIRO H1167-06); tip of lower opercular spine below posterior margin of opercle; jaws with long, widely spaced canine teeth; premaxillary teeth generally in single straight row (posteriormost teeth in 2 irregular rows), totaling ca. 40 teeth. Colouration: head and body uniformly vivid red in fresh specimens, caudal fin and oral membrane uniformly pale in preserved specimens (Ref. 123746).

Estimates based on models

Phylogenetic diversity index (Ref. 82804):  PD50 = No PD50 data   [Uniqueness, from 0.5 = low to 2.0 = high].
Bayesian length-weight: a=0.01047 (0.00417 - 0.02629), b=3.04 (2.82 - 3.26), in cm total length, based on LWR estimates for this (Sub)family-body shape (Ref. 93245).
Trophic level (Ref. 69278):  3.2   ±0.4 se; based on size and trophs of closest relatives
Fishing Vulnerability (Ref. 59153):  Low vulnerability (10 of 100).
