Short description Identification keys | Morphology | Morphometrics

Dorsal spines (total): 23 - 28; Dorsal soft rays (total): 60 - 75; Anal spines: 2 - 3; Anal soft rays: 61 - 83; Vertebrae: 71 - 85. Diagnosis: 22+1 - 27+1 (median 24+1) dorsal spines; postorbital length relatively short, 53.3-62.6% HL (mean 58.2%); pectoral fin relatively long, 24.7-38.1% HL (mean 30.5%); distance from anterior border of snout to last externally visible dorsal spine 53.9-62.2% SL (mean 57.1%), decreasing with size; origin of soft dorsal fin at about same level as origin of soft anal fin; lower jaw length relatively short, 14.4-23.1% HL (mean 18.3%), increasing with size; origin of first dorsal spine situated before, below, or just posterior to posterior edge of pectoral fin, (-27.9)-2.0% HL [mean (-12.7%)]; distance from gill opening to dorsal pectoral fin base 4.3-9.6% HL (mean 6.9%) (Ref. 81678).

Estimates based on models

Phylogenetic diversity index (Ref. 82804):  PD50 = 0.5000   [Uniqueness, from 0.5 = low to 2.0 = high].
Bayesian length-weight: a=0.00257 (0.00122 - 0.00544), b=2.97 (2.79 - 3.15), in cm total length, based on LWR estimates for this (Sub)family-body shape (Ref. 93245).
Trophic level (Ref. 69278):  3.8   ±0.6 se; based on size and trophs of closest relatives
Resilience (Ref. 120179):  Medium, minimum population doubling time 1.4 - 4.4 years (Preliminary K or Fecundity.).
Fishing Vulnerability (Ref. 59153):  Low to moderate vulnerability (30 of 100).
Nutrients (Ref. 124155):  Calcium = 258 [126, 651] mg/100g; Iron = 2.23 [0.95, 4.84] mg/100g; Protein = 16.9 [15.1, 18.7] %; Omega3 = 0.268 [0.105, 0.667] g/100g; Selenium = 27.1 [7.0, 105.0] μg/100g; VitaminA = 72.1 [23.9, 221.8] μg/100g; Zinc = 1.75 [0.91, 3.65] mg/100g (wet weight);
