Some snakes, such as boas, rattlesnakes and garter snakes, give birth to live young. That means that the baby snakes develop inside their mother. When they are born they are covered with a thin membrane, kind of like a goopy baggie. The baby uses an egg tooth to rip out of the membrane and wriggle free.

Yes. Unlike humans, most reptiles are born as fully functioning miniature adults. Anecdotally, baby brown snakes are more dangerous than adults. Adult snakes have learned that not every stike requires envenomation.

Rattlesnakes are best known for, and most easily recognized by, their rattle. The rattlesnake babies are born with what is called a pre-button. The baby snake loses this piece when it sheds its skin for the first time. With the shedding a new button appears.

Even more amazing is the facts that some types of snakes develop the eggs inside of the female body, but in the end, they give birth to live young. Most snake species, around 70% of them reproduce by laying eggs, and 30% give birth to live young, like rattlesnakes, vipers, boas and most of the sea snake species.

Pythons and boa constrictors have tiny hind leg bones buried in muscles toward their tail ends. ... Vestigial legs are a clue that snakes descended from lizards.
