Etymology: Bathyraja: Greek, bathys = deep + Latin, raja, -ae = a ray (Raja sp) (Ref. 45335).

生態学
海 底生の; 深さの範囲 20 - 1110 m (Ref. 50550). Temperate
Northwest Pacific: Sea of Okhotsk off Hokkaido, Japan to the Kamchatka Peninsula.
Length at first maturity / サイズ / 重さ / 年齢
Maturity: Lm 68.5, range 61 - 76 cm
Max length : 102 cm TL オス/雌雄の選別がない; (Ref. 52075)
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 8.5 cm long and 6.7 cm wide (Ref. 41249).
Life cycle and mating behavior

Oviparous, paired eggs are laid. Embryos feed solely on yolk (Ref. 50449). Distinct pairing with embrace. Young may tend to follow large objects, such as their mother (Ref. 205).
