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.Those living species of sea snails range in size from Syrinx aruanus, the largest living shelled gastropod species at 91 cm (36 in), to minute species whose shells are less than 1 mm at adult size.
