Maturity: L_m ? range ? - ? cm
Max length : 35.0 cm TL male/unsexed; (Ref. 106604)

Inhabits the deeper parts of the continental slope and on slopes of submarine banks (Ref. 3167). Feeds on all kinds of bottom animals (Ref. 3167). Oviparous (Ref. 50449). Eggs have horn-like projections on the shell (Ref. 205).

Oviparous (Ref. 3167). Paired eggs are laid. Embryos feed solely on yolk (Ref. 50449).

Estimates based on models

Preferred temperature (Ref. 123201): 7.1 - 8.8, mean 8.3 °C (based on 13 cells).

Phylogenetic diversity index (Ref. 82804): PD₅₀ = 0.5312 [Uniqueness, from 0.5 = low to 2.0 = high].

Bayesian length-weight: a=0.00302 (0.00141 - 0.00645), b=3.24 (3.07 - 3.41), in cm total length, based on LWR estimates for this (Sub)family-body shape (Ref. 93245).

Trophic level (Ref. 69278): 3.5 ±0.37 se; based on food items.

Resilience (Ref. 120179): Low, minimum population doubling time 4.5 - 14 years (Fec assumed to be <100).

Fishing Vulnerability (Ref. 59153): Low vulnerability (25 of 100).

Nutrients (Ref. 124155): Calcium = 7.88 [1.21, 155.60] mg/100g; Iron = 0.377 [0.036, 5.033] mg/100g; Protein = 15.1 [13.0, 17.2] %; Omega3 = 0.538 [0.202, 1.418] g/100g; Selenium = 14.8 [2.5, 73.9] μg/100g; VitaminA = 6.05 [0.43, 76.69] μg/100g; Zinc = 0.341 [0.023, 3.869] mg/100g (wet weight);
