Life cycle and mating behavior

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).全世界的熱帶水域。 西大西洋: 美國南卡羅萊那州到阿根廷。 時常與 Myliobatis freminvillii 互相混淆。
