Viviparous
Viviparous is a method of
animal reproduction in which the embryo develops inside the body of the mother from which it gains nourishment, and not from an
egg. Viviparous offspring live independently and require an external food supply from birth. Vivipary is best developed in placental
mammals, but also occurs in many
reptiles, and a few
fishes.
