How do earthworms escape from enemies?
The setae stick to dirt and the worm then contracts its body to force itself through soil. The worm also secretes a mucus that helps it slide through dirt more quickly. In fact, to escape the cold of winter or an eager predator, the earthworm can burrow dozens of feet below the surface.
How does an earthworm carry out respiration?
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.
