Description of 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). Adults of both sexes congregate during the breeding season in shallow bays and estuaries and likewise leave when the pupping season is over after mating (Ref. 48844). Gestation lasts for about 12 months (Ref. 48844).
