Limacology

Limacology, from Latin limax, "slug", and -logy from Ancient Greek λόγος (lógos), meaning "study", is the branch of zoology which deals with slugs, i.e. shell-less gastropod mollusks. A person that studies limacology is referred to as a limacologist.

However, slugs are an extremely polyphyletic group, thus "limacology" is not a taxonomically accurate term, and it is now rarely used.
