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
Possibly a junior synonym of A. hyperborea due to strong morphological similarity according to Ebert & Stehmann (2013, Ref. 98315) and Weigmann (2016, Ref. 118749) (Ref. 118749).
