This species is distinguished from its congeners Bathyraja in having a white blotches of different sizes on the dorsal surface of the disk, lateral folds of tail are broad; clasper has a large pseudosiphon; dense silky fibers covering egg capsule (Ref. 75535).
Body shape (shape guide): other.
Body shape (shape guide): other.
Exhibited migratory pattern of going toward greater depths during colder months for overwintering, while in the warm period, this species predominantly fed at shallower depths Oviparous. Distinct pairing with embrace. Young may tend to follow large objects, such as their mother (Ref. 205). Eggs are oblong capsules with stiff pointed horns at the corners deposited in sandy or muddy flats (Ref. 205). Egg capsules are 10.19 cm long and 6.28 cm wide (Ref. 41249).
