Ovoviviparous animals are similar to viviparous species in which there is internal fertilization and the young are born live, but differ in that there is no placental connection and the unborn young are nourished by egg yolk; the mother's body does provide gas exchange (sharks and rays). The terms "ovoviviparity" or "aplacental viviparity" have been deprecated because they encompass several unrelated modes of reproduction. In some species, the internally developing embryos rely solely on yolk. This is known as "yolk-sac viviparity" and is regarded as a type of lecithotrophy (no maternal provisioning).Other species exhibit matrotrophy, in which the embryo exhausts its yolk supply early in gestation and mother provides additional nutrition. This additional provisioning may be in the form of unfertilized eggs (intrauterine oophagy), uterine secretions (histotrophy), or it may be delivered through a placenta. The first two of these modes were categorized under aplacental viviparity."@en }
