Etymology: Amblyraja: Greek, amblys = darkness + Latin, raja, -ae = ray (Raja sp.) (Ref. 45335).
Eponymy: This is a toponym referring to the fact that the holotype was caught in the coastal waters of South Georgia and was named after that island. (Ref. 128868), visit book page.

生物學特性     字彙 (例如 epibenthic)

Found on continental and insular shelves, as well as upper slopes. Feeds mainly on small benthic invertebrates (Ref. 114953). Oviparous (Ref. 205). Reaches maturity at 80-90 cm TL; birth size at ca. 20 cm TL (Ref. 114953). 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 capsule measures 116.5 mm long and 80.0 mm wide (Ref. 41249). Utilized as fishmeal and possibly not utilized for human consumption due to extreme roughness of its squamation (Ref. 5159).

用來作魚粉了而且可能地沒有被用作人類的消費由於它的鱗片的排列的極端粗糙.(參考文獻 5159) 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) 卵鞘有 116.5 mm 長與 80.0 mm 寬的長。 (參考文獻 41249)

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). Eggs have horn-like projections on the shell (Ref. 205).東南太平洋: 智利.(參考文獻 27540) 南極海: 南喬治亞島的周圍與在向西的脊上向布拉克岩礁。 偶然地在 Scotia 脊上見到。
