What does viviparous mean?

Answer 1

An animal that is viviparous gives birth to live young. The opposite is oviparous, meaning that it lays eggs.

Answer 2

Viviparous refers to a reproductive method where offspring develop inside the body of the parent and are born live, as seen in most mammals. This is different from oviparous species that lay eggs and allow them to develop outside the parent's body.
