All snakes belong to the class Reptilia.

Snakes have an evolution history of 130 million years.

There are about 3000 species of snakes in the world.

Snakes can be divided into 3 groups: Primitive Snakes, Blind Snakes and Advanced Snakes.

All snakes reproduce sexually and with their own species.

Snakes do not chew their food. They are able to swallow their prey whole, as their jaws are extendable.

Pythons can ingest 400 times their daily energy requirements in one meal.

Snake's venom is used to make anti-venom vaccines.

Snakes will only feed, mate and produce offspring when their body temperature is in the perfect range.

A snake stores fat in its body therefore some snakes can exist for months without eating.

The study of snakes is called Herpetology.

All snakes, if threatened, defend themselves by biting. However, only few of them are deadly venomous.

Though the snakes skin appears moist, but in reality all snakes have dry skin, often with a polished gloss that helps them travel fast by reducing the frictional force.

Some snakes like to move around only during daylight (diurnal) and others like to move around only at night (nocturnal).

The rains make all the snakes more active and alert.

Since snakes have been robbed of their eardrums through the process of evolution, many people think that snakes are deaf. It is not true. However, it is true that snakes seem not to react to high frequency airborne sounds, that's why a rattlesnake cannot hear its rattle, but they are very sensitive to vibrations of low frequency received through the surface on which they are resting.

Some snakes such as pit vipers are equipped with special sensory system, called pits, found mostly on the side of the face or on lips, to detect infra-red radiation. These pits known as the most sensitive heat receptors in the animal world, not only distinguish the direction of an object that differs in temperature from background, but also it's distance. They can sense even the slightest change in temperature of 0.001 Celsius degrees. Thus, a rattlesnake can find and strike a mouse in total darkness.

Snakes use their tongues to collect chemical signals, which helps them in locating their prey, recognizing a predator and finding a mate.
