Ovoviviparous Animals: Definition, Characteristics and Examples

Ovoviviparous Animals – There are three types of reproduction in the animal kingdom, namely the oviparous (egg-laying), viviparous (dwelling) and ovoviviparous (egg-laying) ways. The three ways of reproduction also have different characteristics. The following is an explanation of ovoviviparous animal reproduction.

Ovoviviparous definition

Ovovivipar is a way of animal reproduction by multiplying eggs in the mother’s body, but the food reserves obtained by the embryo come from inside the egg, not from the mother’s body. Ovoviviparous animals do not have a placenta to provide food, oxygen and exchange of wastes.

This animal also does not have an umbilical cord to connect the embryo with its mother. To make it clearer, ovoviviparous animals are types of animals that reproduce by oviparous (laying eggs) and viviparous (giving birth). Ovoviviparous animals are also often referred to as animals that lay eggs because they use both reproductive systems. There are 2 types of ovoviviparous animals based on their habitat, namely ovoviviparous animals living in water and ovoviviparous animals living on land.
