The snakes are distinguished by the complete absence of limbs. The largest snakes are in the boa family. They are sluggish on land. The pythons have small spurs that are vestiges of hind limbs. they are at home in jungles & climb trees! the egg eating species of snakes, one is found in INDIA too. They glide through foliage of trees searching for birds nests.
The snakes have long bodies without limbs. They move about with a swimming motion by twisting their bodies into sideways curves. some are good at swimming, climbing or burrowing & others can glide through air. snakes are not slimy creatures. . Just because snakes do not have legs now, does not mean that they didn't have them a sometime in the course of their development. but how & why they came to lose their legs is not yet known to scienceSome experts believe that the ancestors of snakes were certain kinds of burrowing lizards. There are many kinds of such lizards today, & all of them have very small legs or no legs at all. In time, the legs disappointed altogetherThere are four ways in which snakes move. One of them is called " Lateral undulatory movement". In this method, the snake forms its body into a number of wavy, S shaped curves. By pressing backward & outward against rough places on the ground, the snake slips forward on those scales.
A second way snakes move is called " rectilinear movement". In this case, small groups of the belly scales are pulled forward on part of the body, while other scales project backward to keep the snake from slipping back. Then the scales that have been holding the body are pulled forward. the scales that moved first hold the body.
A third way is a "Concertina" method, which is used for climbing. The snake wraps its tail & rear part of the body around a tree, stretches out the forepart of its body & hooks it on the tree higher up. Then it releases the rear part & pulls the rest of its body upwards.
"Sidewinding" is another method by which snakes move. A loop of the forebody is thrown to one side. Then the rear part is shifted to the new position, & another neck loop is thrown out.

NO.. snakes are reptiles WITHOUT legs (limbs).. There are, however, amphibian type reptiles that have legs, or small limbs, etc but are NOT in the same family as snakes
