How Does Snake Locomotion Work?

Snake locomotion is like sliding on a slippery floor using your belly and legs, but without legs!

Snakes move by contracting and expanding their bodies in waves. Imagine you're wearing a really stretchy shirt, and you squish it from one side to the other, that’s how snakes push themselves forward.

Think of a snake as like a ruler made of soft links. When one part of the ruler pushes against the ground, the next part slides forward, just like when you slide your hand along a table and then pull it back. Snakes do this all over their body to move slowly but surely.

Snakes use friction on the ground to help them move. If there’s more friction (like on rough grass), they can push harder. On smooth surfaces, like a floor, they might slide more, just like how you might slip on a wet tile!

Sometimes, snakes even use their tails to help them move faster or turn around, it's like giving themselves an extra pair of feet!
