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)

生物學特性     字彙 (例如 epibenthic)

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。 明顯的成對出現。 幼魚可能傾向跟隨大的個體, 例如他們的母親.(參考文獻 205) 卵為長方形鞘囊具有僵硬的觸角沈積在沙灘或泥灘的角落.(參考文獻 205) 卵鞘是 15.66 公分長與 8.0 公分寬的.(參考文獻 41249) 經常地被拖網誤捕了而且可能是用作魚粉。

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)
