Photo of the day (21): Radix auricularia

Radix auricularia is a freshwater snail from the family Lymnaeidae. This species is native to Eurasia.

The shell of an adult snail has an ear shaped aperture, but I have taken photos af a juvenile snail.  The height of the shell of this juvenile snail is 14 mm. All of these photos shows the same specimen.
