Achtung, folks! If you are planning to do any mollusk collecting or mollusk photography in Europe, you will find this set of 6 plastic-coated identification cards very useful. Each card is about 29.5x21.5 cm and features color photos of the shells of the most common central European mollusks along with their common and up to date scientific names.
The cards are double-sided, so on 6 cards you get a lot of creatures, including Landschnecken und Nacktschnecken (land snails and naked snails, that is, slugs, of course), Süsswassermollusken (freshwater mollusks) and not only the mollusks but also some other shore creatures, including crabs and shrimps of Nordsee und Ostsee (North Sea and East Sea. East Sea? Oh, they mean the Baltic Sea). Yes, the cards are in German, but that shouldn't prevent them from being useful. Besides, you'll have an excuse, if you need one, to learn a few words of German.
The set was prepared by Vollrath Wiese und Ira Richling of the nature museum Haus der Natur in Cismar, Germany. I bought my set at the World Congress of Malacology in Antwerp. The cards are available from my friend Francisco Welter-Schultes's company Planet Poster Editions.
