SNAKES AND LIZARDS

Hi, snakes and lizards are ancient animals. They both are reptiles. Modern reptiles were first seen 250 million years ago! All reptiles are cold blooded. That means that their body temperature changes by the things they are standing by. They are more active when the weather is warm. In cold weather they barely move and they crawl into a burrow until the weather changes. Lizards are more common than snakes. Snakes and lizards are alike and different in many ways because snakes don't have legs, snakes don't have any ears in their heads,  snakes don't have real eyelids, and snakes can open their mouth wider. Maybe I'll study more about snakes and lizards when I grow up.
