Épines dorsales (Total) : 7 - 10; Rayons mous dorsaux (Total) : 17 - 23; Épines anales: 0; Rayons mous anaux: 12 - 17. Yellowish with brown spots, most numerous on back; narrow stripes on soft dorsal, pectoral and caudal fins, with dark spots on fin rays (Ref. 4698). Head height equal to head width. Males with a long pointed genital papilla (Ref. 35388).

Found on muddy, sandy or rocky bottoms or among algae (Ref. 4698). Maximum depth at 930 m (Ref. 58426). Benthic (Ref. 58426). Feeds on benthic polychaetes, crustaceans (Hyppolyte, Boreophausia), and large hyperiids (Phascolosoma) (Ref. 4698). Males usually below 7 cm and females below 12 cm. Lives at temperatures -1.7-10°C. Female lays 150-1,000 eggs with a diameter of 3mm (Ref. 35388).

Estimates based on models

Preferred temperature (Ref. 123201): -1.3 - 4.6, mean 0.2 °C (based on 3829 cells).

Phylogenetic diversity index (Ref. 82804): PD₅₀ = 0.5000 [Uniqueness, from 0.5 = low to 2.0 = high].

Bayesian length-weight: a=0.00776 (0.00450 - 0.01340), b=3.19 (3.04 - 3.34), in cm total length, based on LWR estimates for this species & (Sub)family-body (Ref. 93245).

Niveau trophique (Ref. 69278): 3.1 ±0.35 se; based on food items.

Résilience (Ref. 120179): Milieu, temps minimum de doublement de population : 1,4 à 4,4 années (Preliminary K or Fecundity.).

Fishing Vulnerability (Ref. 59153): Low vulnerability (10 of 100).

Nutrients (Ref. 124155): Calcium = 67 [25, 167] mg/100g; Iron = 0.491 [0.206, 1.230] mg/100g; Protein = 16.3 [14.1, 18.5] %; Omega3 = 0.407 [0.152, 1.269] g/100g; Selenium = 17.8 [6.1, 46.0] μg/100g; VitaminA = 21.2 [4.2, 104.9] μg/100g; Zinc = 0.671 [0.402, 1.188] mg/100g (wet weight);
