| Banana slugs are hermaphroditic, possessing both male and female genitalia. Though they are capable of self-fertilization, cross mating is more typical slug behavior. When a slug is ready to mate, it will release pheromones into its slime as a signal to other slugs. The slugs release sperm into each other and fertilize the eggs. After mating, the slugs will gnaw off each others male genitalia to disengage. Sperm collected in this fashion can be stored internally for several months, to allow immature eggs to fully develop before fertilization. | Banana slugs are hermaphroditic, possessing both male and female genitalia.

| - | Many animals are predators of the banana slug, including birds, raccoons, snakes, and salamanders. However, due to the mucous secreted by the slug, most such predators will roll the slug around in the dirt to remove the slime before eating the slug.((http://bss.sfsu.edu/holzman/courses/fall00projects/bananaslug.html)) | + | Many animals are predators of the banana slug, including birds, raccoons, snakes, and salamanders.
