Freshwater snails are gastropod mollusks that live in fresh water. There are many different families. 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.
Physa fontinalis, common name the common bladder snail, is a species of air-breathing freshwater snail, an aquatic gastropod mollusc in the family Physidae. The shells of species in the genus Physa are left-handed or sinistral .
Neritidae, common name the nerites, is a taxonomic family of small to medium-sized saltwater and freshwater snails which have a gill and a distinctive operculum. [2] The family Neritidae includes marine genera such as Nerita, marine and freshwater genera such as Neritina, and freshwater and brackish water genera such as Theodoxus.
Biomphalaria is a genus of air-breathing freshwater snails, aquatic pulmonates belonging to the family Planorbidae, the ram's horn snails and their allies. [3] [4] Biomphalaria is the type genus of the tribe Biomphalariini. Both Planorbis and Taphius are synonyms for Biomphalaria. [3] [5]
Shells of the freshwater snail Theodoxus danubialis Shells of the land snail species Helicina rostrata Titiscania, a shellless neritimorph. Despite their relatively low diversity, with only around 2,000 species, neritomorphs have achieved a remarkable diversity of forms, resembling a smaller-scale version of the diversity achieved by Gastropoda as a whole.

These fresh water snails are present in aquariums and ponds, as well as in wild areas. They are also commonly referred to as tadpole snails or pouch snails. They eat algae, diatoms and detritus, including dead leaves. The populations are regulated by the abundance of food and space. They are widespread, abundant, and tolerant to pollution.
These snails eat dead plant and animal matter and various other detritus. Because Physella acuta forages mainly on epiphytic vegetation and on the macrophytes, whereas other gastropods ( Planorbis planorbis , Radix ovata ) exploit the algal cover or phytobentos on the bottom, competition between Physella acuta and other gastropods appears to be ...
