Determinatiesleutels | Morfologie | Morfometrie
This species is distinguished from its congeners in Bathyraja in having a dark greyish brown color on both sides of the body; its clasper rather short with a shallow cleft; distance between extremity of pseudosiphon and tip of clasper is wide (Ref. 75535).
Body shape (shape guide): other.
Oviparous (Ref. 50449). Eggs have horn-like projections on the shell (Ref. 205).
