簡短描述
型態特徵 | 形態測量圖
脊椎骨: 113 - 117. This species is distinguished from its congeners Bathyraja in having a whitish brown coloration on the ventral surface of the disk, contrasting the dark greyish brown on other parts; scapular spine absent; row of middorsal spines uninterrupted, running from before scapular arch to first dorsal (Ref. 75535).
Oviparous (Ref. 50449). Eggs have horn-like projections on the shell (Ref. 205). Depth range given by H. Ishihara (pers.comm. 07/07).
卵生的.(參考文獻 50449) 卵在貝殼上有像觸角一樣的突出。 (參考文獻 205) 被 H. Ishihara 給的深度範圍 (pers.comm。 07/07).
