Short description Identification keys | Morphology | Morphometrics

Dorsal soft rays (total): 16 - 18; Anal soft rays: 35 - 39; Vertebrae: 38. Distinguished from other congeners by the combination of the following characters: gill rakers 22-24; scales on lateral line 100-110; scales rows above lateral line 48-56; predorsal scales 55-64; circumpeduncular scales 32-36; one or two bifurcate spines in the ventral keel; dark blotches, with ill-defined contour, sometimes forming transversal bars in the flanks (Ref. 81196).

Estimates based on models

Phylogenetic diversity index (Ref. 82804): PD₅₀ = 0.5001 [Uniqueness, from 0.5 = low to 2.0 = high].

Bayesian length-weight: a=0.02884 (0.01251 - 0.06647), b=3.09 (2.91 - 3.27), in cm total length, based on LWR estimates for this Genus-body shape (Ref. 93245).

Trophic level (Ref. 69278): 3.4 ±0.6 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).
