Both shells are colored to help the turtle blend in with the 2 environments in which it lives. All turtles lay their eggs on land. Turtles do not contain teeth, but use a horny beak to grab and tear food. Turtles contain three eyelids. Lizards and snakes are examples.
Lizards are the most abundant.
They range in size from the large Komodo Dragon to the small tropical geckos. Snakes probably developed from small burrowing lizards. They are void of legs, eyelids, and ears, and are carnivores, swallowing their prey whole. Their glottis and gullet are at separate ends of the mouth cavity. They contain 2 rows of teeth on the upper jaw and one row on the lower.
