The snake is a legged reptile with a long stature. Snakes have scales like lizards and are equally classified into scaly reptiles (Squamata). The difference is lizards are generally legged, have ear holes, and eyelids that can be opened close. However, for cases of legless lizards. This difference becomes blurred and can not be used as a handle.

But the snake can still be distinguished because the snake has no ears and eyelids. Snakes are one of the most successful reptiles in the world. In mountains, forests, deserts, lowlands, farmlands, settlement environments, to the ocean, snakes can be found.

However, like most cold-blooded animals, snakes are increasingly rare in cold places, such as on mountain peaks, in the Irish and New Zealand regions and snow-or-polar regions. There are many types of snakes that live all the time in the trees and almost never step on the ground. Many other species live on the ground or infiltrate under litter or piles of rocks.

While others live aquatic or semi-aquatic in rivers, swamps, lakes and seas. Snakes prey on different types of animals smaller than their bodies. Sea snakes feed on fish, frogs, tadpoles, and even fish eggs. Tree snakes and land snakes feed on birds, mammals, frogs, other types of reptiles, including eggs. Big snakes like pythons can prey on goats, deer, deer and even humans.
