Apophallation is a tactic occasionally used by hermaphroditic terrestrial gastropods during copulation. The mating rituals of some of these species involve two specimens wrapping their penises into a spiral and exchanging semen between them. However, once mating is complete, it is sometimes impossible for the couple to separate, thus requiring them to amputate one of the penises by chewing it off.
