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, a very reduced shell, or only a small internal shell, particularly sea slugs and semislugs. Various taxonomic families of land slugs form part of several quite different evolutionary lineages, which also include snails. The shell-less condition has arisen many times independently during evolutionary past, and thus category “slug” is a polyphyletic one. Pulmonata, Onchidiacea and Soleolifera solely comprise. A third family, Sigmurethra, contains various clades of snails, semi-slugs (i.e. snails whose shells are too small for them to retract fully into) and slugs.
