Rajidae (Skates)
Etymology: Amblyraja: Greek, amblys = darkness + Latin, raja, -ae = ray (Raja sp.) (Ref. 45335).
Eponymy: Professor Adolf Severin Jensen (1866–1953) was a Danish zoologist, ichthyologist and malacologist. [...] (Ref. 128868), visit book page.
Taxonomic Remarks
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).

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).
Body shape (shape guide): other.
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).
