They are grouped into two large subclasses, the gill-breathing, operculated Prosobranchia and the lung-breathing, non-operculated Pulmonata.Caenogastropoda is the most diverse clade of gastropods, including about 157 extant families, 190 extinct families (Bouchet et al., 2017), and 60% of living snail species (>23,000; WoRMS). They are incredibly varied in morphology, ecology, and behavior. Most are marine, but others live in freshwater and on land. Gastropods, or univalves, are the largest and most successful class of molluscs. 60,000–75,000 known living species belong to it. Most of are marine, but many live in freshwater or on land.
