The deep-sea skate, Bathyraja abyssicola, is a large-sized species with a maximum total length of about 1.2 m (Ishihara & Ishiyama, 1985). The inverse heart-shaped disc (main part of the animal) bears one or three median nuchal thorns. There is no scapular thorn on shoulders of the disc. The tails bears 25-31 median thorns. Both sides (ventral and dorsal) of the disc and tail are armed with minute fine prickles. This species occurs widely from the Pacific coasts of North America to the Pacific coast of northern Japan at depths from 362-2,906 m (Ishihara & Ishiyama, 1985; Hatooka et al., 2000). The record at the depth of 2,906 is the deepest catch of any skate or ray (Grey, 1956).
