Question

How many legs does a snake have?

Answer 1

Hint: Snakes are vertebrate organisms and are ectothermic, they belong to class reptilia of the kingdom Animalia. They are cold blooded animals.

Complete answer:
1)The convergent evolution has resulted in the formation of snakes without any limbs, so basically snakes do not have any legs and thus snakes are known as limbless reptiles.
2)There are some species of snakes such as python and boas that have two small vestigial legs present near the cloaca that are not used in locomotion.
3)Therefore, snakes have no legs.

4)Snakes are carnivorous organisms and snakes have only one lung and the kidneys of snakes are present one after the other so that more space can exist inside the snake to consume its prey. Snakes are known to evolve from lizards in the cretaceous period.
5)There are almost 2900 species of snakes and the snakes are found everywhere but snakes are not found in the Antarctic regions.

Note: Snakes belong to phylum Chordata and order Squamata and suborder Serpentes. Serpentes are also classified into two infra orders are alethinophidia and scolecophidia and the snakes are covered by the scale. Snakes are of two types, venomous and nonvenomous, the venomous snake contains a poison that is used to kill the prey and it is also used for self-defense and this poison can cause serious injury and death in humans also. The nonvenomous snake does not contain any such poison.
