Siklus hidup dan perilaku kawin Kematangan | Reproduksi, perkembang biakan | Pemijahan | telur-telur | Fekunditas | Larva

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). Distinct pairing with embrace (Ref. 205). Young are born at about 30 cm disc width (Ref. 6871).
