Quick Summary

Serpentine locomotion is a method of movement used by limbless vertebrates, most commonly by snakes, legless lizards, amphisbaenids, and caecilians. This type of locomotion involves the body being thrown into a series of sinuous curves.1

In serpentine locomotion, the snake's body moves in S-shaped loops. Each loop pushes against environmental resistance, such as rocks or twigs, to propel the snake forward. The entire body moves together, with all parts following the path of the head. This method is highly effective on surfaces that provide sufficient resistance.21

In serpentine locomotion, in which the body is thrown into a series of sinuous curves, the movements appear identical to those of anguilliform swimming, but the similarity is more apparent than real. Unlike anguilliform swimming, when a snake starts to move, the entire…

Locomotion
The first method, called serpentine locomotion, is shared with almost all legless animals, such as some lizards, the caecilians, earthworms, and others. This is the way most snakes move and has been seen by any zoo visitor. The body assumes a series of S-shaped horizontal loops, and each loop…
