Dorsal spines (total): 11; Dorsal soft rays (total): 12 - 14; Anal spines: 4; Anal soft rays: 8 - 10. Body with about equal stripes of brownish red and silvery white; spinous dorsal mostly white, membrane tips yellow, basal part of fin red except base of first two membranes which are whitish (Ref. 4201).

Estimates based on models
Preferred temperature (Ref.
123201): 25.4 - 28.9, mean 27.2 °C (based on 435 cells).
Phylogenetic diversity index (Ref.
82804): PD
50 = 0.5000 [Uniqueness, from 0.5 = low to 2.0 = high].
Bayesian length-weight: a=0.01622 (0.00774 - 0.03400), b=2.97 (2.80 - 3.14), in cm total length, based on LWR estimates for this Genus-body shape (Ref.
93245).
Trophic level (Ref.
69278): 3.6 ±0.5 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 (17 of 100).
Nutrients (Ref.
124155): Calcium = 58.9 [23.4, 216.2] mg/100g; Iron = 0.517 [0.197, 1.555] mg/100g; Protein = 18.7 [17.5, 19.9] %; Omega3 = 0.117 [0.051, 0.276] g/100g; Selenium = 22.2 [12.6, 43.7] μg/100g; VitaminA = 76.3 [27.1, 211.2] μg/100g; Zinc = 1.92 [0.81, 3.78] mg/100g (wet weight);
