In [[animal]]s, '''viviparity''' is development of the [[embryo]] inside the body of the mother, with the maternal circulation providing for the metabolic needs of the embryo's development, until the mother gives [[birth]] to a fully or partially developed [[juvenile (organism)|juvenile]] that is at least metabolically independent. This is opposed to [[oviparity]], where the embryos develop independently outside the mother in [[egg]]s until they are developed enough to break out as [[hatchling]]s;<ref name=":0" /> and [[ovoviviparity]], where the embryos are developed in eggs that remain carried inside the mother's body until the hatchlings emerge from the mother as juveniles, similar to a live birth.
