Short description Identification keys | Morphology | Morphometrics

Dorsal spines (total): 11 - 13; Dorsal soft rays (total): 6 - 8; Anal spines: 11 - 12; Anal soft rays: 10 - 11. Dorsal fin with 11-13 spines. Anal fin with 11-12 spines and 10-11 segmented rays. In live male, dorsal, anal and caudal fins with a narrow greenish-bluish margin and a black subdistal band bordered proximally by a blue iridescent band, very narrow in caudal, wider (especially anteriorly) in anal and dorsal. Proximal part of dorsal and anal black along body, grading into red distally, usually forming a conspicuous black blotch at posterior end of dorsal base. Proximal part of caudal fin deep black, grading into bright red patch. Pelvic fin and filament blue (Ref. 56232).

Facultative air-breathing (Ref. 126274)

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=0.00389 (0.00180 - 0.00842), b=3.12 (2.94 - 3.30), in cm total length, based on all LWR estimates for this body shape (Ref. 93245).

Trophic level (Ref. 69278): 3.1 ±0.4 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).
