Quizplus · Accepted Answer

Fertilization in earthworms occurs through the exchange of spermatozoa between two individuals during copulation. The spermatozoa are stored in the seminal vesicles and are released onto the clitellum during copulation. The clitellum then secretes mucous that collects the spermatozoa and eggs and forms a cocoon around them. The cocoon eventually hardens and develops into a tiny worm, which hatches from the cocoon.
