Eastern Atlantic and Mediterranean Sea: Central to South Eastern Atlantic: Morocco, Mauritania to Congo (Ref. 33465) to Natal, South Africa (Ref. 5578); Mediterranean Sea: the records are patchy along the northern coast of Africa, and in Aegean Sea and Levantine Basin, most likely due to misidentification with other Dasyatidae spp. (Ref. 122045 and others cited).

Exhibit ovoviparity (aplacental viviparity), with embryos feeding initially on yolk, then receiving additional nourishment from the mother by indirect absorption of uterine fluid enriched with mucus, fat or protein through specialised structures (Ref. 50449). With 1 to 4 in a litter (Ref. 12951). Distinct pairing with embrace (Ref. 205).東大西洋與地中海: 摩洛哥，茅利塔尼亞到剛果.(參考文獻 33465) 範圍延伸到南非的納塔爾。 (參考文獻 5578)
