Short description Identification keys | Morphology | Morphometrics

Dorsal spines (total): 5 - 6; Dorsal soft rays (total): 13 - 14; Anal spines: 0; Anal soft rays: 11 - 12; Vertebrae: 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).
Trophic level (Ref. 69278):  3.7   ±0.3 se; based on size and trophs of closest relatives
Fishing Vulnerability (Ref. 59153):  Low vulnerability (16 of 100).
Price category (Ref. 80766):   Unknown.
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.
