What is nematode?

A nematode is like a tiny, squishy worm that lives almost everywhere you can imagine, in soil, in water, even inside other creatures.

Imagine you have a rubber band. Now stretch it out and squish it into a long, thin shape, that’s kind of what a nematode looks like! They’re super small, often no bigger than the tip of your pencil. You can find them in gardens, in lakes, even inside your pet dog or cat.

Nematodes don’t have legs or wings, they just wiggle and slide through dirt or water to move around. Some are helpful, like the ones that help plants grow by eating bad bugs in the soil. Others are not so friendly, they might live inside your pet and make them sick.

Some nematodes are even used by scientists, because they’re so simple and easy to study! You can think of them as little helpers who let us learn about how living things work.
