Short description Morphology | Morphometrics

Dorsal spines (total): 11; Dorsal soft rays (total): 16-17; Anal spines: 3; Anal soft rays: 8. This species is distinguished by the following set of characters: D XI,16 (rarely XI,17); A III,8; pectoral-fin rays 18; lateral-line scales 48-52 (modally 48 and 50); longitudinal scale series 114-132 (120 and 128); total gill rakers 21-24 (22); body deep, its depth 30.7-42.7 (mean 35.3) % SL; the 1st to 3rd dorsal-fn spine lengths gradually increasing, 3rd or 4th (rarely 5th) spine longest; anal-fin posterior margin is rounded; caudal fin truncate, the posterior margin with narrow white line; head, body, and all fins have small polygonal brown spots (smaller than pupil, expanded on head and body undersurface) on pale background, forming a reticulate pattern; pectoral fin is brown, with its margin yellow when fresh (brownish in preserved specimens) (Ref. 123820)..

Estimates based on models

Phylogenetic diversity index (Ref. 82805):  PD50 = No PD50 data   [Uniqueness, from 0.5 = low to 2.0 = high].
Bayesian length-weight: a=0.01148 (0.00558 - 0.02364), b=3.04 (2.87 - 3.21), in cm total length, based on LWR estimates for this Genus-body shape (Ref. 93245).
Trophic level (Ref. 69278):  3.9   ±0.6 se; based on size and trophs of closest relatives
Resilience (Ref. 120179):  Low, minimum population doubling time 4.5 - 14 years (Preliminary K or Fecundity.).
Vulnerability (Ref. 59153):  Moderate to high vulnerability (45 of 100) .
