3rd European Workshop on Scaphopod Molluscs


The last workshop was few months ago and we come already closer to the next workshop. The report on the 3rd European workshop on scaphopod molluscs is published in Spirula (journal of the Dutch Malacological Society) this week. You can read and download the report here: LINK.

Dr. Bernd Sahlmann, Frans de Jong and I had erect at April 28th, 2013 to May 1st, 2013 the first European workshop on Scaphopod Molluscs, at Haus der Natur – Cismar. A German shell museum, directed by dr. Vollrath Wiese, who had helped and enjoyed us during our stay.

The journey went easy. When we arrived we were in luck that there was a meeting of “Club Conchylia”, so we were allowed to see some shells while enjoying a cup of tea and a lovely piece of home-made cake. We didn’t wait long before Karina Thiede and her husband arrived. I had made an appointment to get some great pieces of “Sternberger gestein”. A very Scaphopod-rich formation from the Chattium (A and B), Oligocene age. I will study those Scaphopods later.

The following days we tried to find an ID on our difficulties, but every solved problem gave us a lot more new questions. We also discussed some matters on anatomy, biology, distribution, morphology and nomenclature.

During our one-day discussion about the Red Sea Scaphopods, we have solved a lot of problems. The most things are more clear now and ready to publish. Vollrath has helped us with his photograph skills to make fantastic, detailed pictures of these white, striated shells.

I want to thanks Bernd and Vollrath for their hospitality, lot of information, and humoristic moments, Vollrath earns special honor for his photograph skills. We have laughed a lot, and the cakes were very tasteful. Thanks to Frans for his accompaniment during this trip.

A nice day on the intertidal zone of Yerseke, or not?

With the theme of the exotic species living in the Oosterschelde (the Netherlands), after the success of the ”Gorishoek excursion” (see: LINK) and the great stories we’ve heard about Yerseke made Frans de Jong and I decided to go on excursion to Yerseke on July 22th, 2012.

After meeting each other on the parking lot next of Youth Centre ”De Zealte” on the Korringaweg we looked for a suitable location to go down of the sea dyke. When we arrived without sliding at the foot of the dyke, and skimmed the inventarisation area, it seemed pretty similar to Gorishoek. Only it is much dirtier and full of blue mussels (Mytilus edulis). If you look to the ground you can easily pick empty shells of the common limpet (Patella vulgata) and single valves of The queen scallop (Aequipecten opercularis). Still no Atlantic oyster drill (Urosalpinx cinerea) of the bristly crab (Pilumnus hirtellus), species for which we actually did come to Yerseke. A few meters to the water, in some pools, I saw impressive big examples of the

some of them are near the 3 centimetres. During the return to our car we saw a nice crab, not a bristly crab, but I think it is a brush-clawed shore crab (Hemigrapsus takanoi), an exotic species that repulse our aboriginal crabs, but I’m not sure about the determination. Collected that one and went to the car, and on to the other search spot near Yerseke …

the breakwaters. After a short discussion we decided to go to work island Neeltje Jans and continue our search on the North sea side of the island. There we only saw much common limpets, flat periwinkles (Littorina fabilis), a large grey top shell (Gibbula cineraria), some pullet carpet shells (Venerupis senegalensis), one living dog whelk (Nucella lapillus), a nice coloured crab, I think it is Japanese shore crab (Hemigrapsus sanguineus) and some smaller shells of the Cuttlefish (Sepia officinalis) at the south of the island.

Afterwards we enjoyed a delicious barbecue at the campsite where I stayed. Altogether it was not a bad day.
