Length at first maturity / 大小 / 重量 / 年齡
Maturity: Lm 194.5, range 189 - 200 cm
Max length : 270 cm TL 雄魚/尚未辨別雌雄; (Ref. 3263)
背棘 (總數): 0; 背的軟條 (總數): 0. A giant plain stingray with a broadly pointed snout, small eyes and a round disc; tail short with a long caudal fin and a narrow sting; upper surface covered with denticles (Ref. 5578). Grey-black to brownish or purplish-brown above, white below; rear edges of pelvic fins and tail grey; disc edges black, and sting light (Ref. 5578).
一個龐大的單色魟具有一個尖端寬的吻，小的眼與一個圓的體盤; 尾部很短的有一個長的尾鰭與一個狹窄的刺; 上表皮覆蓋著細齒了。 (參考文獻 5578) 灰黑色的對褐色或紫褐色的上方, 腹面白色的; 腹鰭與尾部後緣灰色的; 體盤邊緣黑色, 與刺的顏色較淡.(參考文獻 5578)
Found on the outer shelf and upper slope (Ref. 5578), on soft bottoms (Ref. 9914) at depths of 275-680 m (Ref.58048). Benthic (Ref. 58302). Feeds on small pelagic fish, eels, crabs, shrimp, lobsters, cephalopods and polychaete worms (Ref. 5578). The specimen taken from a depth of 44 m was caught off Mozambique (Ref. 9914). Its sting is long and can inflict a painful wound if handled. Caught occasionally by demersal longline fisheries in deepwater. Utilized for its meat, but not of a particularly high value (Ref.58048).
在軟質底部上, 棲息於外部的大陸棚與上層斜坡 (參考文獻 5578).。 (參考文獻 9914) 底棲的.(參考文獻 58302) 吃小型大洋性魚類魚，鰻魚，螃蟹，蝦，龍蝦，頭足類動物與多毛類的蠕蟲。 (參考文獻 5578) 取自深度的標本 44 公尺被捕捉莫三比克外海.(參考文獻 9914)
