Earthworms

---

This is the head of the worm.	This is the body of the worm when you cut the worm in half it still moves for about a day. When you do split it in half it still wiggles because of the muscles in the body. So it's like you made it two worms.	A cocoon is no bigger than a pin. Each one holds one worm. The cocoon holds all the fiber and nutrient the embryo worm needs.
.Earthworms can't see they use touch-sencitve organs. Worms don't have a nose like we do they use chemoreceptors or sence organs. Worms don't breathe through their mouth like we do, they breathe skin!
