It lives in depths ranging from 15 to 1602 meters in North Pacific Ocean from northern parts of Japan to the Aleutian Islands and southeastern Alaska and south to northern California.

[1][2] It has a maximum total length of 161 centimeters.

[2][3] It is the most abundant species of the Bathyraja genus in the eastern Bering Sea slope and throughout the Gulf of Alaska.

[1] It is oviparous[2] and produces oblong egg capsules with stiff horn in each corner.

The embryo gets its nutrients from the yolk which is at first utilized for growth at a relatively constant rate but later in the development the yolk is absorbed rapidly.
