Life cycle and mating behavior
Kematangan | Reproduksi, perkembang biakan | Pemijahan | telur-telur | Fecundity | 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).
