Common name for members of the class Gastropoda (phylum Mollusca).

The subclass Prosobranchiata, the operculate snails, includes the order Neogastropoda, which includes the venomous stinging cone snails (genus Conus), and the order Mesogastropoda, of which the family Hydrobiidae includes most of the medically important host snails.
