The Great Ramshorn Snail

There is still a lot of activity in ponds. We haven't had a frost yet and Pond Snails, water-lice and ponds skaters go about their lives as usual. This is a Great Ramshorn Snail, Planorbarius corneus, inhabitant of still or slow moving waters with a high calcium content and plenty of vegetation. Unlike land snails, Ramshorn Snail's eyes are at the base of their long tentacles. They graze algae and plants or feed on dead leaves. They are hermaphrodite, although they prefer to cross-fertilise one another. They will lay their gelatinous egg batches on the underside of leaves. I photographed it on the white bowl with some rain water.
