Quick Summary

The term "Aulacopoda" refers to a suborder within the class Gastropoda, which are commonly known as snails and slugs. Gastropods are a diverse group of mollusks with over 65,000 species found in marine, freshwater, and land environments.1

The classification of gastropods has been a subject of ongoing debate, with revisions based on traditional anatomy, shell features, and molecular studies. Within the Gastropoda, Aulacopoda is a group of three superfamilies: Succineacea (amber snails), Arionacea (including slugs), and Limacacea (also including slugs). These groups are characterized by specific features of their radula (a ribbon of tiny teeth) and reproductive organs.1
