Difference between Lizards and Snakes (Lizards vs Snakes)

The lizards are most typical of the modern reptiles, showing the least modification in body form.  They usually have an elongated body, along tail and 4 well developed clawed pentadactyl limbs adapted for climbing and digging. The tail of most lizards is easily broken off when threatened or seized by a predator. The ability is known as autonomy. The fact that tail breaks up easily is of great survival value.  While the predator is a  attracted to and eats the wriggling tail, the lizard quietly escapes. The majority of lizards are carnivorous, feeding largely on insects, worms and other small animals. Most lizards are oviparous. Their eggs, protected by thin shells with little time, are laid on land.

Snakes have long cylindrical body without limbs covered with scales and immovable eyelids.  The body is covered by overlapping scales which are differentiated into shields and plates. The large ventral scutes are used In locomotion. The locomotion is brought about by lateral body wall muscles through movement of ribs.
