Viviparity is the development of young within the body of the mother, where the mother's body supplies all of the nourishment necessary for the development of the foetus. Human beings are a viviparous species. Oviparity is the development of young within an egg which is deposited outside the body of the mother and hatches outside. The nourishment which the infant needs is wholly contained in the egg. Ovoviviparity is a system midway between the two, where an egg is created with nourishment enough for the infant to grow, but it is not laid, but hatches within the body of the mother. To external appearance, an ovoviviparous species appears to be a viviparous one.
