About
As its name suggests, the Great Pond Snail lives in larger ponds, lakes and slow moving water in Europe, North America and parts of Asia. With a shell of up to 54mm in height, it is one of the larger aquatic freshwater snails. Great Pond Snails breathe by coming up to the surface for air using an air bubble inside their shells and let themselves drop to the bottom of a lake when feeling threatened. They survive harsh winters by staying under the ice and using the small amounts of oxygen in the water itself, breathing through their skin.
While the Great Pond Snail is not considered vulnerable yet, it might be in the near future if marshes and natural lakes get even more contaminated or dry out completely. The snail needs clear water for reproduction but can survive in muddy water once fully grown. This species can live for up to 2 years and is hermaphroditic, laying around 300 eggs if conditions are right.
