Viviparity (vivipary)—the embryo matures inside mum, followed by a live birth. Ovoviviparous animals produce eggs, but instead of laying, the eggs develop within the mother's body. In oviparous animals, fertilization takes place internally but embryo development takes place externally. Ovoviviparous definition, producing eggs that are hatched within the body, so that the young are born alive but without placental attachment, as certain reptiles or fishes. Viviparity, retention and growth of the fertilized egg within the maternal body until the young animal, as a larva or newborn, is capable of independent existence.The growing embryo derives continuous nourishment from the mother, usually through a placenta or similar structure.

(In the case of guppies, females can store extra sperm and can use it to fertilize eggs for up to eight months.) All nutrients are received from the mother by diffusion from her circulatory system. Increased levels of apoptosis may be the result of the cost of maintaining a larger phenotype as standard metabolic rate scales approximately with mass (Coelho and Moore, 1989;Calder, 1996) and may put larger females at a reproductive disadvantage in situations of prolonged nutritional stress. Unlike most species of snakes that lay eggs, pit vipers are most commonly ovoviviparous. The Human Life Cycle . Ovoviviparity. The eggs of birds such as hen and duck carry immature embryo in them.
