small snail found in freshwater pond near Dartmoor. dark brown with paler brown spots.
No interactions present.
Do you have an estimate of length? L. glabra would be 12-20mm when mature, and this appears smaller (of course, it could be a juvenile). Also, do you know whether it had an operculum (a hard plate acting as a door when the snail withdraws) and what soil underlies the pond (i.e. given the location, whether the pond would be slightly acid or not)?
