What do they look like? Earthworms are smooth-skinned worms, with a body made of many small segments. If you look at the body you can see lines that mark the segments. Each segment has stiff little hairs that help the worm move, sometimes the hairs are hard to see. They have no skeleton, but do have lots of muscles. Earthworms don't have much coloration, so they usually look white, gray, pink, or reddish brown. Some earthworms have red blood, and you can see it through their skin. Their skin produces slimy mucus that helps them slide through the soil. Like most animals they have a front and back end, and their mouth and tiny brain are at the front.
