How do worms move?
The inner layer of muscles are longitudinal, which shorten but widen the body when contracted. Every segment of a worm's body (except the first and last) has four pairs of tiny, stiff hair-like projections called setae. To move forward, this is what a worm does:First it grips the soil with some of its back setae so its back part can't move.Then it squeezes its circular muscles, which makes its body get longer.

Breathing: Worms breathe air in and carbon dioxide out, just like us, but they don't have lungs. They can't breathe through their mouth, and certainly can't breathe through their nose because they don't even have one! They breathe through their skin. Air dissolves on the mucus of their skin, so they MUST stay moist to breathe. If worms dry out, they suffocate. As fresh air is taken in through the skin, oxygen is drawn into the worm's circulatory system, and the worm's hearts pump the oxygenated blood to the head area. The movements of the worm's body make the blood flow back to the back end of the body, and the hearts pump the blood forward again. Carbon dioxide dissolves out of the blood back to the skin.
