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.

Other snails have adapted to an existence in ditches, near deepwater hydrothermal vents, in oceanic trenches 10,000 meters (6 miles) below the surface, [17] the pounding surf of rocky shores, caves, and many other diverse areas. Gastropods can be accidentally transferred from one habitat to another by other animals, e.g. by birds. [18]
