Pond snails enjoying leaves of  terrestial plants that have fallen in the water

 

Pond snail; Great pond snail

Mudatigu ehk mudakukk

Lymnaea stagnalis

 

One of our commonest species of snails in waters. It is an aquatic pulmonate  or lung-breathing mollusc belonging to the Lymnaeinae family and it can be found in slowly flowing or standing fresh waters. It moves in the water along aquatic plants and every now and then rises to the surface to breathe – as the description pulmonate, and the Estonian name kopstigu, lung snail, says.

 

The shell can be up to five centimetres long, darkish-coloured on a living snail; an empty shell is yellowish-white and partly translucent.
