Biology
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 [733]. Reproductive cycle appears to be annual in males and biannual in females (Ref. 48844). No defined birthing season (Ref. 48844).
