Ovoviviparous: when living young are born from eggs which are hatched in the body of the parent. Explanation of Terms Used in Entomology | John. B. Smith Descending a little lower, we come to the oviparous and ovoviviparous tribes.
Ovoviviparity. Ovoviviparous animals are similar to viviparous species in which there is internal fertilization and the young ones are born alive, but differ in that there is no placental connection and the unborn young ones are nourished by egg yolk; the mother's body does provide gas exchange (sharks and rays).. In some species, the internally developing embryos rely solely on yolk.
A. Viviparous B. Ovoviviparous C. Oviparous. Answer to Question #3. C is correct. While monotremes still use milk to nourish their young, they retain the ancestral form of laying eggs to develop young. Based on this, it is assumed that viviparity is a derived trait in the rest of the mammals, and that it arose after mammals evolved mammary ...
Unlike viviparous and ovoviviparous animals which carry their developing young with them, oviparous animals must protect or hide their eggs for the duration of development. Many birds must sit on their eggs frequently to keep them warm, or even constantly in the case of cold-climate birds like penguins.

Ovoviviparous animals do not have an umbilical cord to attach the embryos to their mother or a placenta to provide food, oxygen, and waste exchange. They are nourished by the egg yolk of their egg. After hatching, while still in the mother, they may be nourished by secretions, unfertilized egg yolks, or cannibalizing their siblings.
Oviparous animals, such as birds and many reptiles, are reproduced through eggs that the females deposit in the environment (in a process known as "laying"), and after a period of incubation, these eggs hatch from them and start a new life.. In viviparous animals, which comprise the majority of mammals, such as dogs or humans, the embryos develop inside the mother's womb, in a struct...
