The Hydrobiidae family can be characterised by its ‘cosmopolitan’ distribution, meaning that is essentially locatable almost anywhere in the world. This family is locatable in freshwater habitats only, however, Gastropods as a class are widely spread through marine and land environments as well. Marine and land species account for 93%  of the Gastropod class population meaning that freshwater species’ make up only 7%. This is due to the fact that snails and slugs are better adapted to marine and land environments. As a result of this, some species of Hydrobiidae, such as Beddomeia camensis, are limited to a small selection of freshwater environments that can sufficiently support their life.
