Into three major groups the first, and largest, contains snake and lizards this stately specimen is an iguana from Central America. Like all other reptiles, both snakes and lizards are cold-blooded. That's to say their body temperature stays close to that of their surroundings. And, with the exception of a few species, Such as this water snake, Most of the world's many snakes and lizards live on dry land. Turtles are the next big reptile group. They, as our little friend here demonstrates, are the only reptiles with a shell. There are many kinds of turtles. Some, such as this giant tortoise, live on land, while others are at home in fresh water. In addition, some turtles, Such as the one these scientists are studying, spend most of their lives in the ocean. Alligators, crocodiles, and their kin Make up the last major reptile group. Powerful predators, these mighty reptiles spend much of their time in the water or sunning themselves on the shore nearby.
Crocodilia - As the name suggests, this order of reptiles includes about 23 species of crocodiles, alligators, gharials and caimans. In all, there are approximately 25 individual species of reptile within the Crocodilia order.
Squamata - This order of reptiles includes snakes and lizards. So as you might imagine, it is by far the largest order of reptiles, including more than 7,000 individual species.
Testudines - This reptile order is made up of turtles and tortoises. Under the current system of reptile classification, there are approximately 300 species of turtle and tortoise in the Testudines order of reptiles.
Sphenodontia - This is the least known and smallest order of reptiles. It is comprised of only two species of tuataras from New Zealand. The tuatara resembles a lizard, but it is equally related to both snakes and lizards. It is the last living member of this group of reptiles, which flourished around 200 million years ago toward the end of the "Dinosaur Era."
The largest group of reptiles is the squamates, which includes lizards and snakes. This group is diverse, with over 10,000 species identified to date.
