Several years ago when we posted a response that mentioned that all snails and slugs are Hermaphrodites, so all pairings are same sex, we incurred the wrath of a particularly sensitive reader. The facts have not changed on this issue, and slugs are still hermaphrodites. This species is commonly called the Spotted Leopard Slug, the Tiger Slug, or the Great Grey Slug. More can be read on this Oregon State University website.
