Pomatiopsidae is a family of small, mainly freshwater snails, (some also occur in other habitats) that have gills and an operculum, aquatic gastropod mollusks in the superfamily Truncatelloidea (according to the taxonomy of the Gastropoda by Bouchet & Rocroi, 2005).
Pomatiopsidae are well known as intermediate hosts of Asian schistosomes. [1]
Species in the family Pomatiopsidae occur worldwide. [1] The generic diversity of Pomatiopsinae is particularly high in the Japanese Archipelago, where four of the eight genera, including two endemics, are recorded. [1] The subfamily Triculinae radiated as aquatic snails in freshwater habitats in Southeast Asia. [1]
The American malacologist William Stimpson first defined this taxon as Pomatiopsinae in 1865. [4] Stimpson's diagnosis reads as follows: [4]
Pomatiopsinae, with the shell and operculum as in the Rissoinae. Foot with lateral sinuses. Size small. Amphibious. Genus Pomatiopsis , Tryon.
The family Pomatiopsidae consists of 2 subfamilies (according to the taxonomy of the Gastropoda by Bouchet & Rocroi, 2005) [5] that follows classification by Davis (1979): [6]
Family-group name Rehderiellinae Brandt, 1974 [12] is also in Pomatiopsidae, but it is not allocated in detail. [5]
Genera within the family Pomatiopsidae include:
Subfamily Pomatiopsinae
Subfamily Triculinae - there are over 20 genera in Triculinae [1]
tribe Triculuni
tribe Jullieniini
tribe Lacunopsini
tribe Pachydrobiini
Rehderiellinae is not allocated to a subfamily [5]
The Pomatiopsidae have various life habits: aquatic, amphibious, littoral, halophilic, cavernicolous and even terrestrial. [1] [13] Terrestrial taxa occur only on the Japanese Archipelago located in East Asia ( Blanfordia ). [1] Tomichia and Coxiella include several halophilic species occurring on saline lakes. [1]
Pomatiopsidae invaded freshwater habitats from marine ones in one or in two independent lineages. [20] They also invaded terrestrial habitats from freshwater habitats in two independent lineages. [1]

Littorinimorpha is a large order of snails, gastropods, consisting primarily of sea snails, but also including some freshwater snails and land snails.
Oncomelania hupensis is a species of very small tropical freshwater snail, an aquatic gastropod mollusk in the family Pomatiopsidae.
Viviparidae, sometimes known as the river snails or mystery snails, are a family of large operculate freshwater snails, aquatic gastropod mollusks.
Tricula is a genus of freshwater snails with a gill and an operculum, aquatic gastropod mollusks in the family Pomatiopsidae.
Amnicolidae is a family of small freshwater snails with a gill and an operculum, aquatic gastropod mollusks in the superfamily Rissooidea.

Freshwater snails are gastropod mollusks that live in fresh water. There are many different families. They are found throughout the world in various habitats, ranging from ephemeral pools to the largest lakes, and from small seeps and springs to major rivers. The great majority of freshwater gastropods have a shell, with very few exceptions. Some groups of snails that live in freshwater respire using gills, whereas other groups need to reach the surface to breathe air. In addition, some are amphibious and have both gills and a lung. Most feed on algae, but many are detritivores and some are filter feeders.
