Freshwater snail



This photo shows the courtship behaviour of freshwater snails. I also observed that this freshwater snail grazes on the leaf surface of aquatic plants. They seem to graze on the epiphyte (algae growing on the leaf surface). Do you know the inter-relationship bewteen freshwater snails and the aquatic plants? It the relationship beneficial to both partners?
