Life cycle and mating behavior
Maturity | Reproduction | Spawning | Eggs | Fecundity | Larvae
Members of the class Clitellata are copulating hermaphrodites. The clitellum, their distinctive feature from polychaetes, serves as a tool in reproduction. It secretes mucus for copulation and forms a cocoon where eggs and albumen are deposited. Life cycle: Zygotes develop in the cocoon and emerge as juveniles which later develop into adults.
