Great Pond Snail

Lymnaea stagnalis

This is a common species of Europe's largest air-breathing water snails. It can grow to 6 cm tall and 3 cv wide. The colour of the shell varies due to different compositions of the coating.

The great pond snail can be observed from early spring to late Autumn in ponds, small lakes, or quiet pools. The species is distributed throughout Europe and North Asia, occurring as far the Kamchatka Penninsula.

It feeds on aquatic plants and dead matter, and sometimes on fish eggs, hydras, and protozoa. The great pond snail is the intermediary host of the common liver fluke, a parasitic worm.
