Etymology: Amblyraja: Greek, amblys = darkness + Latin, raja, -ae = ray (Raja sp.) (Ref. 45335).
Eponymy: Thomas Frerichs was captain of the research vessel ‘Walther Herwig’ from which the holotype was collected. He was honoured for: “…his keen interest in deepsea catches, which assured us many precious discoveries”. (Ref. 128868), visit book page.
Taxonomic Remarks
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).
