Elasmobranchii
板鳃亚纲 (鲨鱼与 鱼) (sharks and rays) >
Rajiformes (Skates and rays) >
Arhynchobatidae (Softnose skates)
Etymology: Bathyraja: Greek, bathys = deep + Latin, raja, -ae = a ray (Raja sp) (Ref. 45335).
Environment: milieu / climate zone / depth range / distribution range
生态学
海洋 居于水底的; 深度上下限 91 - 500 m (Ref. 5179). 極; 48°S - 65°S, 79°W - 84°E
Southern Ocean: Orkney and South Shetland islands to the Antarctic Peninsula. Probably more widespread in continental waters into the Weddell Sea and eastward as well as into the Pacific Ocean sector westward. Southeast Pacific: Chile (Ref. 9068).
南極海: 奧克尼群島與雪特蘭群島南部到南極半島。 可能更廣泛分佈在大陸的水域中進入威德爾海之內與東方的以及進入太平洋地區之內西方的。 東南太平洋: 智利.(參考文獻 9068)
大小 / 重量 / 年龄
Maturity: Lm ?  range ? - ? cm
Max length : 120 cm TL 雄鱼/尚未辨别雌雄; (Ref. )
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 15.66 cm long and 8.0 cm wide (Ref. 41249). Regularly taken as bycatch in trawl hauls and may be used as fishmeal. Minimum depth from Ref. 58018.
卵生的。 明显的成对出现。 幼鱼可能倾向跟随大的个体, 例如他们的母亲.(参考文献 205) 卵为长方形鞘囊具有僵硬的触角沈积在沙滩或泥滩的角落.(参考文献 205) 卵鞘是 15.66 公分长与 8.0 公分宽的.(参考文献 41249) 经常地被拖网误捕了而且可能是用作鱼粉。

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).南極海: 奧克尼群島與雪特蘭群島南部到南極半島。 可能更廣泛分佈在大陸的水域中進入威德爾海之內與東方的以及進入太平洋地區之內西方的。 東南太平洋: 智利.(參考文獻 9068)
