What Is the Classification of a Lizard?

Lizards belong to a class of animals called reptiles, or reptilia, which contains over 8,225 species. Reptiles are cold-blooded vertebrates that breathe air. Most of them are egg-laying, except for some vipers and constrictor snakes as well as some lizards.

There are approximately 3,000 species of lizards. Most of them have legs, but there are some without them. The shape and the length of their tails also vary. One of the smallest lizards is a species of chameleon, which is only 1.6 inches long, while the long Komodo dragon can reach up to 3 meters in length. Lizards are known to live anywhere in the world except in the Antarctic.
