Korte beschrijving Determinatiesleutels | Morfologie | Morfometrie

This species is distinguished from its congeners Bathyraja in having a white blotches of different sizes on the dorsal surface of the disk, lateral folds of tail are broad; clasper has a large pseudosiphon; dense silky fibers covering egg capsule (Ref. 75535).

Holotype taken from a depth of about 450 m (Ref. 26282). Maximum depth based on report for Bering Sea and Aleutian Islands (Ref. 80796). Oviparous. Distinct pairing with embrace. Young may tend to follow large objects, such as their mother (Ref. 205). Eggs are oblong capsules with stiff pointed horns at the corners deposited in sandy or muddy flats (Ref. 205). Egg capsules are 10.19 cm long and 6.28 cm wide (Ref. 41249).

Estimates based on models

Preferred temperature (Ref. 123201): 1.3 - 3.8, mean 2 °C (based on 27 cells).

Fylogenetische diversiteitsindex (Ref. 82804): PD₅₀ = 0.5000 [Uniqueness, from 0.5 = low to 2.0 = high].

Bayesian length-weight: a=0.00331 (0.00211 - 0.00519), b=3.11 (2.98 - 3.24), in cm total length, based on LWR estimates for this species & Genus-body shape (Ref. 93245).

Trofisch niveau (Ref. 69278): 4.1 ±0.71 se; based on food items.

Generation time: 30.5 ( na - na) years. Estimated as median ln(3)/K based on 1 growth studies.

Weerstandsvermogen (Ref. 120179): laag, minimale populatieverdubbelingstijd 4,5-14 jaar (Fec assumed to be <100).

Fishing Vulnerability (Ref. 59153): Very high vulnerability (80 of 100).
