Animals that give live birth have adapted the ability to develop a fetus within themselves instead of having to protect an external egg. For the most part, these are mammals, although the Echidna and the Platypus continue to lay eggs. Keep in mind that all sexually reproducing animals lay eggs, just that mammals keep the egg inside of themselves while every other species does not.
