There are over 3,000 kinds of snakes in the world. Giants snakes like the seven-meter long Python, can swallow a large antelope whole. Other snakes can grow no bigger than a pencil. Some live in the sea, some burrow underground, and others climb trees. All snakes have certain things in common: a long, thin shape; scaly, legless bodies; and unblinking, lidless eyes.
Like all reptiles, snakes rely on the heat of the sun to control their body temperature. The greatest variety of species of snakes is found in the warm, humid tropical regions all around the world. Snakes are shy creatures. But some are in danger of disappearing altogether before we even get a chance to learn about them anything about them.
