(total): 59 - 66;
soft rays: 41 - 45;

Northwest Pacific: Commander Islands and southeastern Kamchatka to the Sea of Okhotsk and northern Sea of Japan. Northeast Pacific: Alaska.
Mainly intertidal, but may be found at depths as much as 100 m (Ref. 43939); typically found shallower than 50 meters (Ref. 51666). Often in bays with pebble-rock debris bottoms (Ref. 43939). Oviparous, eggs are guarded by the female parent (Ref. 58332).
