Snake Emerging From Egg
A green tree python, native to the rain forests of New Guinea and northeastern Australia, emerges from its shell. Most newborn snakes, which must free themselves from tough, leathery eggs, come armed with a single egg tooth, located on their head or snout. The egg tooth is used to tear through the shell and is discarded when the snake first sheds its skin. Thirty percent of snakes, however, give birth to live young. Egg-laying snakes usually live in warmer climates, which helps incubate their eggs.
