The reproductive system of gastropods (slugs and snails) varies greatly from one group to another within this very large and diverse taxonomic class of animals. Their reproductive strategies also vary greatly. In many marine gastropods, there are separate sexes (male and female); most terrestrial gastropods however are hermaphrodites. [citation ...

Land slugs are a highly polyphyletic group, which means that many land slug families are not at all closely related to one another. The majority of land slugs are simultaneous hermaphrodites, meaning they possess both male and female reproductive organs that are functional at the same time. Some species regularly self-fertilise.
Banana slugs are hermaphroditic, meaning they are both male and female at the same time. [3] During reproduction, Ariolimax buttoni engages in apophallation - the behavior in which a slug chews off its mating partner's penis. [5] Their mating season is very long, lasting from February to early September. In addition, the copulation itself is long.

If a banana slug has lost its male sexual organ, it can still mate as a female, making hermaphroditism a valuable adaptation. [22] The species of colourful sea slugs Goniobranchus reticulatus is hermaphroditic, with both male and female organs active at the same time during copulation. After mating, the external portion of the penis detaches ...
The common slug eater usually gives birth to litters of three to twelve young. [8] [9] However, broods from large females may consist of as many as 22 newborns, each measuring eight to eleven cm (3⅛-4¼ inches). The total combined weight of the young may exceed the weight of the female after giving birth.
