Where does fertilization occur in an earthworm?
Fertilization occurs in the mucous tube which is shed from the front end of the earthworm. This dries in the soil to become an egg capsule, from which one or more young earthworms will eventually hatch. Many species can reproduce several times a year.Click to see full answer.

Fertilization occurs in the mucous tube which is shed from the front end of the earthworm. This dries in the soil to become an egg capsule, from which one or more young earthworms will eventually hatch. Many species can reproduce several times a year.Click to see full answer. Simply so, where does Fertilization and development occur in earthworm?Fertilization takes place inside the cocoon, where each ovum is fertilized by sperm. As a rule, there is only one embryo develops (only one fertilized egg proceeds to develop new individual and rest degenerate). So the cocoon contains many fertilized eggs but only one earthworm can release from cocoon.Also, where is sperm stored in earthworms? Sperm are made in the seminal vesicles, which are large organs on either side of the esophogus. Sperm is stored, once it is received, in the seminal receptacles (Loretto). The clitellum, the area where the actual fertilization takes place, is about a third of the way down the worm’s body. Likewise, people ask, do earthworms have internal or external fertilization? Fertilization takes place outside of the female’ body. Earthworms have a modified external fertilization. After copulating during which each hermaphroditic earthworm exchanges sperm with another, earthworms create a cocoon external to their clitellum.Do earthworms fertilize their eggs?Earthworms are hermaphrodites (both female and male organs within the same individual) but generally cannot fertilize their own eggs. They have testes, seminal vesicles and male pores which produce, store and release the sperm, and ovaries and ovipores. Copulation and reproduction are separate processes in earthworms.
