| Earthworms Make Cocoons | | When it reaches adulthood, an earthworm develops a fleshy area on its body called the clitellum. Once it mates, the earthworm produces a sheath with its clitellum and shimmies it down its body. The protein-rich ring moves over tiny holes, where it gathers eggs and some of the collected sperm. Then, it slips off the worm and becomes a cocoon with one or more developing earthworms inside. Below is a link to the part in our video where you can see how a cocoon is formed. | | |
