Chaeta

Okay, so let's talk about chaeta. Have you ever seen a worm or a caterpillar? You know how they have little hairs on their bodies? Well, scientists call those hairs "chaeta".

Chaeta help worms and caterpillars move around in their environment. They use those little hairs to grip onto surfaces so they can crawl around.

But chaeta aren't just used by worms and caterpillars. Some sea creatures like lobsters and crabs also have chaeta on their legs. It helps them move around in the water and catch prey.

So, in short, chaeta are little hairs that help some animals move around and survive in their environment.
