Which freshwater habitats commonly contain snails?

Freshwater snails, which belong to the class Gastropoda, are commonly found in a variety of aquatic environments, including:

• Lakes12
• Ponds12
• Rivers12
• Streams12
• Marshes2

While these habitats typically host only a few species at any single location, those species often possess wide geographic ranges. In certain ancient river systems and lakes—such as Lake Baikal, Lake Titicaca, Lake Ohrid, the Mekong basin, and the African Rift lakes—complex radiations have resulted in a significantly higher number of species. Additionally, some species may be found in irrigated fields, where they can thrive alongside agricultural activities.23
