Oviparous species enclose eggs in an egg case and deposit them into the environment, where embryos develop external to the body of the mother . .Embryos remain in the egg case to develop for a period ranging from Authors may regard the two terms as synonymous, or equate ovoviviparity only with aplacental yolk-sac viviparity, in which the embryos are solely sustained by yolk (as opposed to secondary provisioning by their mother in the form of "uterine milk", such as in the stingrays, or unfertilized eggs, such as in the mackerel sharks; the latter is referred to as intrauterine oophagy). viviparity Definitions.

Oviparity is a mode of reproduction in which animals lay eggs. Ovoviviparity is a mode in which animals lay eggs and keep them inside the mother’s body until hatching. Viviparity is the mode of reproduction in which animals directly give birth to young ones. parity and limited-histotroph viviparity (aplacental vivipar-ity), however the lack of a well-corroborated phylogenetic hypothesis for the family and for the order hinders infer-ences regarding the frequency, timing and consequences of changes between those two reproductive modes in the evo-lutionary history of these sharks.

Ovoviviparity is otherwise also known as, ‘Aplacental viviparity.’ In the case of ovoviviparous animals, the fertilization of the eggs occurs internally due to mating between the male and the female sexual organs.
