What is Absence of wheels in animal bodies?

Some animals don't have wheels to move, they use different parts instead.

Imagine you're playing with your toy car. It has wheels, so it rolls smoothly on the floor. Now think about a little bug crawling on your leg. It doesn’t have wheels, it moves using its legs, like tiny feet that walk one after another.

Some animals, like cats or dogs, use their feet to run and jump around. They don't need wheels because they can push off the ground with their feet. That’s like hopping on a trampoline, you use your legs to move, not wheels.

Other animals, like snakes, don’t have legs at all! They slither along by moving their body in waves. It's like when you wiggle through a tunnel, no legs or wheels needed!

So even though some animals don't have wheels, they still get around just fine, using feet, legs, or even their whole bodies to move from one place to another. Some animals don't have wheels to move, they use different parts instead.
