Animals giving birth to young ones are called viviparous animals.
The egg of these animals typically contains less yolk insufficient to support the development of the zygote into an embryo.
Hence, development proceeds inside the body of the female animal, and the fully developed embryo is delivered.
Oviparous animals lay eggs.
Their egg typically has more amount of yolk and can support the development of the zygote into an embryo outside the body of the mother.
Ovoviviparous animals lay eggs and develop the eggs inside the mother's body.
