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). Distinct pairing with embrace (Ref. 205). During courtship, the male will hold onto the pectoral margin of a female (sometimes for hours) as she swims through the water. The male flips under the female and inserts a clasper. The male beats his tail from side to side to move the clasper backward and forward in the cloca. Copulation lasts 3-5 minutes. Males have been observed to nudge the female's abdomen during parturition. Viviparous, young born at about 36 cm WD (Ref. 6871).
