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. | Lateral undulation is the type of locomotion usually associated with snakes i.e. side to side wriggling.
