Order - Serpentes

(Snakes)

Snakes have a long, legless, flexible body that is covered with dry scales. When snakes move about on land, they usually slide on their belly. Snake's eyes are covered by clear scales rather than movable eyelids; therefore, their eyes are always open. They repeatedly flick out their narrow, forked tongue, using it to bring odors to a special sense organ in the mouth. Snakes belong to the order of animals called reptiles.

 

There are about 2,400 species of snakes in the world. They live almost everywhere, in deserts, forests, oceans, streams, and lakes. Some are ground dwellers, others live in trees, and other snakes spend most of their lives in water. There are a few areas where snakes do not live. They cannot survive in places where the ground stays frozen the year around, so they are missing in the polar regions or at high mountain elevations.
