Short description
Dorsal spines (total): 9; Dorsal soft rays (total): 22 - 26; Anal spines: 3; Anal soft rays: 18 - 22; Vertebrae: 24. This species is distinguished by the following characters: posterior margin of upper jaw canted posteroventrally; the lachrymal and expanded part of the maxilla densely covered with scales; a well-defined opercular spot, nearly solid black and approximately the diameter of the pupil; caudal vertebra 14; gill rakers, upper 10-15, lower 24-28, total 35-43; lateral line with 37-48 scales in the curved portion and 24-35 posterior scutes; never developing a yellow mid-lateral body stripe; second dorsal and anal fins transparent or dusky green, no yellow pigmentation.

Estimates based on models
Preferred temperature (Ref. 123201): 16.1 - 22.8, mean 18 °C (based on 172 cells).
Phylogenetic diversity index (Ref. 82804): PD50 = 0.5625 [Uniqueness, from 0.5 = low to 2.0 = high].
Bayesian length-weight: a=0.01349 (0.00646 - 0.02815), b=2.96 (2.79 - 3.13), in cm total length, based on LWR estimates for this (Sub)family-body shape (Ref. 93245).
Trophic level (Ref. 69278): 3.4 ±0.3 se; Based on diet studies.
Resilience (Ref. 120179): Medium, minimum population doubling time 1.4 - 4.4 years (Preliminary K or Fecundity.).
Fishing vulnerability (Ref. 59153): Moderate to high vulnerability (54 of 100).
Price category (Ref. 80766): Medium; Very questionable: based on ex-vessel price for species in this family.
Nutrients (Ref. 124155): Calcium = 39 [19, 93] mg/100g; Iron = 0.518 [0.278, 1.036] mg/100g; Protein = 19.7 [18.5, 21.0] %; Omega3 = 0.612 [0.332, 1.186] g/100g; Selenium = 8.61 [3.98, 18.59] μg/100g; VitaminA = 9.84 [2.68, 35.36] μg/100g; Zinc = 0.663 [0.453, 0.947] mg/100g (wet weight);
