Observation - Lymnaea stagnalis - UK and Ireland. Description: These pond snails, Lymnaea stagnalis, are from a garden pond in Bracknell, Berkshire. Every year the tadpoles in this pond are seen grazing on the snails. I had assumed they were only grazing the algae, but it seems they remove some of the snails’ shells

These pond snails, Lymnaea stagnalis, are from a garden pond in Bracknell, Berkshire. Every year the tadpoles in this pond are seen grazing on the snails. I had assumed they were only grazing the algae, but it seems they remove some of the snails’ shells too. I have not noticed this in other ponds. Is this a common occurrence?
