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).西南大西洋。 這種的有效性在 Compagno 1999 名錄懷疑了。 (參考文獻 35766)
