Mammals are the only animals that give birth to live offspring. All other animals lay eggs.
Answer:
Bearing live young (viviparity) has evolved more than 120 times in vertebrates. The species featuring this facility are:
- some fish (sharks and rays),
- some amphibians (certain salamanders and caecilians)
- mammals (with the exception of monetremes)
- reptile species are mostly egg layers but viviparity occurs in some Squamata (lizards, snakes and amphisbians).
