Journey of a black land slug | World of tiny animals |

Rain and autumn set the perfect conditions for slugs to appear. Slug, or land slug, is a common name for any apparently shell-less terrestrial gastropod mollusc. The word slug is also often used as part of the common name of any gastropod mollusc that has no shell. Without such shells, slugs produce mucus, that may also contain toxins-to deter predators.
