Amphibolacea
gastropod superfamily
Quick Summary
The Amphibolacea is a superfamily within the subclass Pulmonata, which are gastropods (snails and slugs) that breathe air using a pulmonary sac. Amphibolacea are characterized by having an operculum (a protective cover for the shell opening), a conical shell, and a pulmonary cavity. They are typically found in brackish water and burrow in sand. The genus Amphibola is a notable example, found commonly in New Zealand and unique among Pulmonata for possessing a well-developed operculum.12
