The great pond snail is a species of large air-breathing freshwater snail. The adult shell is around 6 centimetres long and 3 centimetres wide. It is shiny yellowish brown in colour and has pointed upper whorls and an inflated final whorl.
The great pond snail can be observed from early spring to late autumn in freshwater ponds, small lakes or quiet pools. It is distributed throughout Europe and North Asia, as far the Kamchatka Peninsula in the Russian Far East.
These snails feed on aquatic plants and dead vegetation, and sometimes on fish eggs, hydra and protozoa. The great pond snail is the intermediary host of the common liver fluke, a parasitic worm.
