					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.
