Here is an unsorted collection of pictures of different snails. I plan to organise this page once I have plenty of time ;o).

Limnaea stagnalis
 

Lithoglyphus naticoides

Aplexa hypnorum from a pond near Oldenburg in NW Germany. The specimen lived for one summer in my aquarium.
 

Holandriana holandrii I found at different localities, the first group is from SE Austria, the second from the Cetina River in Croatia and the third from the Kolpa in Slovenia.

In the Southern Bug in the Ukraine I found Borysthenia naticina.

Another snail from Croatia, from the surrounding of the city Imotski, is Emericia patula.

And finally a tropical apple snail from the pet shop, I have no idea about origin or species (essay writing).
