Since snakes lack limbs locomotion is very different to most other vertebrates. Locomotion is produced by different types of movement based on absence or presence of contact between the animal's body and the medium through which the snake is moving. Most species can use different types of locomotion but some species are specialised and use only one.

==Lateral undulation==

Lateral undulation is the type of locomotion usually associated with snakes (i.e. side to side wriggling). At any given time various areas of the snake’s body are pushing simultaneously against a number of fixed points. As the snake moves forward new contact points are made. This is identical for movement across desert, through branches or swimming.
