The process of using love darts in snails is a form of sexual selection.[2] Prior to copulation, each of the two snails (or slugs) attempts to "shoot" one (or more) darts into the other snail (or slug). There is no organ to receive the dart; this action is more analogous to a stabbing, or to being shot with an arrow or flechette. The dart does not fly through the air to reach its target however; instead it is fired as a contact shot.
