An extensive division, or sub-class, of hermaphrodite gastropods, in which the mantle cavity is modified into an air-breathing organ, as in Helix, or land snails, Limax, or garden slugs, and many pond snails, as Limnæa and Planorbis.

large order of gastropods usually breathing by means of a lung-like sac comprising most land snails and slugs and many freshwater snails

a subclass of the Class Gastropoda. Pulmonates can breathe atmospheric air. The gills are reduced or lost and the mantle cavity works like a lung. Few pulmonates, however, are marine. Most are found in freshwater or on land and include slugs and land snails.

The Pulmonata are an order (sometimes subclass) of snails and slugs that have developed lungs.
