How do segment worms reproduce?
Depending on the species, annelids can reproduce asexually or sexually. Asexual reproduction takes place through a method called fission. During fission, the rear end of the body splits from the rest of the body to form a new annelid. Earthworms do not have the ability to reproduce this way, but they do have the ability to regenerate their posterior segments. Sexual reproduction takes place by species that are hermaprhoditic (some earthworms and many leeches) or species that have separate females and males. During sexual reproduction, fluids are transferred from the male pore to the female ovipore. Annelids tend to mate when conditions are moist or following a rain, meaning they may mate quite frequently throughout the year.
