Épines dorsales (Total) : 5 - 6; Rayons mous dorsaux (Total) : 13 - 14; Épines anales: 0; Rayons mous anaux: 11 - 12; Vertèbres: 29. Diagnosis: Interorbital region concave with the side borders strong and higher. Vomerine teeth well-developed. Bony plates on head and body widely scattered, each with several prickles. Head spines are prominent, suborbital spines distinct and in three paired sets, Lateral line pores on body not emerging in distinct tubes (Ref. 55609). Color pattern on body varies, with or without three irregular brownish bands (Ref. 27363).

Estimates based on models
Preferred temperature (Ref. 123201): 3 - 5.9, mean 4.3 °C (based on 72 cells).
Phylogenetic diversity index (Ref. 82804): PD50 = 0.5039 [Uniqueness, from 0.5 = low to 2.0 = high].
Bayesian length-weight: a=0.00389 (0.00180 - 0.00842), b=3.12 (2.94 - 3.30), in cm total length, based on all LWR estimates for this body shape (Ref. 93245).
Niveau trophique (Ref. 69278): 3.7 ±0.3 se; based on size and trophs of closest relatives
Fishing Vulnerability (Ref. 59153): Low vulnerability (16 of 100).
Nutrients (Ref. 124155): Calcium = 45.2 [22.2, 105.8] mg/100g; Iron = 0.469 [0.226, 0.973] mg/100g; Protein = 14.8 [12.5, 17.8] %; Omega3 = 0.457 [0.172, 1.447] g/100g; Selenium = 20 [7, 52] μg/100g; VitaminA = 18.7 [3.9, 89.1] μg/100g; Zinc = 0.484 [0.316, 0.766] mg/100g (wet weight); based on nutrient studies.
