Oviparous (Ref. 50449). Eggs have horn-like projections on the shell (Ref. 205). Reportedly taken as bycatch in deeper water benthic trawl and longline teleost target fisheries as well as in target longline skate fishing from off Mar del Plata, Argentina (Ref. 104534).

Estimates based on models

Preferred temperature (Ref. 123201): 3.9 - 6, mean 4.6 °C (based on 27 cells).
Phylogenetic diversity index (Ref. 82804):  PD50 = 0.5000   [Uniqueness, from 0.5 = low to 2.0 = high].
Bayesian length-weight: a=0.00550 (0.00291 - 0.01038), b=3.13 (2.97 - 3.29), in cm total length, based on LWR estimates for this Genus-body shape (Ref. 93245).
Trofisk nivå (Ref. 69278):  4.0   ±0.7 se; based on size and trophs of closest relatives
Resiliens (Ref. 120179):  Låg, lägsta populationsfördubblingstid 4,5-14 år (Fec assumed to be <100).
Fishing Vulnerability (Ref. 59153):  High to very high vulnerability (67 of 100).
Price category (Ref. 80766):   Medium.
Nutrients (Ref. 124155):  Calcium = 4.32 [0.65, 78.93] mg/100g; Iron = 0.242 [0.023, 2.796] mg/100g; Protein = 14.9 [13.3, 16.7] %; Omega3 = 0.677 [0.259, 1.711] g/100g; Selenium = 15 [3, 70] μg/100g; VitaminA = 9.8 [0.8, 124.4] μg/100g; Zinc = 0.296 [0.020, 3.302] mg/100g (wet weight); based on nutrient studies.
