snail

(snāl),
Common name for members of the class Gastropoda (phylum Mollusca). The freshwater pulmonate (nonoperculated, air-breathing) snails (subclass Pulmonata, order Basommatophora) include most intermediate hosts of trematodes parasitic in humans and domestic birds and mammals, chiefly in the families Lymnaeidae and Planorbidae. 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.
