How Does Reinventing the Wheel: 5 Species That Roll Work?

Reinventing the wheel means doing something new when it’s already been done, but sometimes animals do it on purpose to help them move!

Rolling is like moving by spinning, just like a wheel on a car. Some animals have parts of their body that work like wheels, helping them roll across the ground.

1. Snails, They use their foot, which is soft and slimy, to slide along. It’s like having a slippery sock you can walk on!
2. Earthworms, They squish and stretch as they move. Think of it like pushing yourself forward through a tunnel made of dirt.
3. Beetles, Some beetles roll in circles when they're scared or trying to get away, using their hard shells like a kind of body shield.
4. Rolling things, Like a ball! A pillbug (also called a roly-poly) rolls up into a ball when it's threatened. It’s like wearing a suit made out of armor and curling up to hide.
5. Spiders, Some spiders can roll across the ground by spinning a kind of thread, using it like a trampoline or a slide.

Sometimes, rolling is faster than walking, just like how your toy car moves when you push it! Reinventing the wheel means doing something new when it’s already been done, but sometimes animals do it on purpose to help them move!
