Short description
Identification keys | Morphology | Morphometrics
Dorsal soft rays (total): 13; Vertebrae: 35. Differs from other species of the genus by the combination of the following characters: long pectoral fins always surpassing pelvic-fin origin; anal fin origin at level of a vertical through fifth or sixth dorsal fin rays; one supraopercular and two humeral spots on flanks; two or three maxillary teeth; 35-38 perforated scales in the lateral series; and 24-27 branched anal fin rays. Distinguishes further from most of its congeners by having deep body (36.9-42.6% SL); large eye (10.2-11.9% SL); maxillary length, 100.0-136.6% interorbital width); and presence of 24-25 gill rakers on first branchial arch (Ref. 55798).

Estimates based on models
Phylogenetic diversity index (Ref.
82804): PD
50 = 0.5000 [Uniqueness, from 0.5 = low to 2.0 = high].
Bayesian length-weight: a=0.01000 (0.00244 - 0.04107), b=3.04 (2.81 - 3.27), in cm total length, based on all LWR estimates for this body shape (Ref.

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.
