Elasmobranchii (tubarões e raias) (sharks and rays) > Rajiformes (Skates and rays) > Rajidae (Skates)
Etymology: Amblyraja: Greek, amblys = darkness + Latin, raja, -ae = ray (Raja sp.) (Ref. 45335).

Issue
Provisionally retained as valid but treated as junior synonym of A. hyperborea by Weigmann (2016, Ref. 106604) due to strong morphological similarity and preliminary molecular data. Further work is needed to resolve this issue (Ref. 118749).

Descrição breve Chaves de identificação | Morfologia | Morfometria

Lacks large thorns on anterior margins and mid posterior parts of pectorals and on either side of mid-dorsal ridge on the disc. Upper surface plain light brown, either grayish or of chocolate hue, darker along margins of fins. Lower surface brownish gray, grayish white or perhaps pure white (Ref. 6902).

Biologia     Glossário (ex. epibenthic)

Benthic (Ref. 58426). Deep-water species. Prefers higher temperatures. Feeds on small fishes and crustaceans (Ref. 6902). Oviparous (Ref. 50449). Eggs have horn-like projections on the shell (Ref. 205). Maximum depth reported taken from Ref. 117245. It may be captured as by-catch in deep water fisheries, but due to its depth preference, it is less likely to be vulnerable (Ref. 117245).

Life cycle and mating behavior Maturities | Reprodução | Spawnings | Egg(s) | Fecundities | Larvas

Oviparous, paired eggs are laid. Embryos feed solely on yolk (Ref. 50449). Eggs have horn-like projections on the shell (Ref. 205).

Estimates based on models

Preferred temperature (Ref. 123201): 3.1 - 4, mean 3.6 °C (based on 69 cells).
Phylogenetic diversity index (Ref. 82804):  PD50 = 0.5010   [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).
