This summer sport divers in the Oosterschelde estuary encountered a new and thus the 58th Dutch sea slug species. This was Aeolidiella sanguinea, for which we propose here as its Dutch name “Verborgen vlokslak” [hidden aeolid nudibranch]. The Dutch name comes from the fact that during the day this slug is inactive, hiding under stones and large shells and is only active at night. As a result, the animals are very difficult to observe for sport divers. This species is identified by the combination of a number of anatomical features and especially the shape of the egg strands.

Dutch harbour porpoises counted


This video is called Harbour Porpoise Species Identification.

On Sunday, September 28, 2014, volunteers of Stichting Rugvin counted 34 harbour porpoises in the National Park Oosterschelde.

Around half past ten in the morning thirty volunteers departed aboard eight ships in line to the eastern part of the Oosterschelde. Nowhere else in the world the number of porpoises is counted in this way. During the scan, there was not much wind, so the animals were easy to find. A total of 34 porpoises were observed, including at least three mother and calf pairs.

Dutch rare sea slug news

The Aeolidiella alderi sea slug was found on the Dutch coast for the first time in the late autumn of 2012. Since then, it was a rare slug. Only a small number of individuals in the westernmost Oosterschelde estuary were recorded. Very recently, more than one slug was found in the central Oosterschelde near Zierikzee with egg capsules and a single individual near Goes. So, the area where these beautiful sea slug has settled has extended considerably, and it seems the species is reproducing successfully in the Zeeland Delta.

Aeolidiella alderi is a not common slug species on the western European coast. It is known from a limited number of places around the British Isles and at the French coast to the Mediterranean.

The Dutch mycological society reports today about Crepidotus cinnabarinus, a fungus which is rare all over Europe and North America.

That species had never been seen in the Netherlands. Until 28 August 2014, in the Hulkesteinse bos woodland in Flevoland province. Six days, later on 3 September, it was found in Zeeland province as well.

Rare oriental pratincole in the Netherlands


This is a video about an oriental pratincole.

Near Sint Philipsland in the Netherlands, there is an oriental pratincole today.

This bird species had only been seen once in the Netherlands before.

Here is a Dutch blog post about this.

According to Dutch Birding, this is a young female.

New sea spider discovery in the Netherlands


This video is called Creatures of the Deep: Sea Spider.

Translated from the Dutch marine biologists of Stichting ANEMOON:

Another marine animal can be added to the Dutch fauna list: a sea spider with the scientific name Endeis spinosa. It is a species that is common in many places of the Northwest European coast, and in the past it was found several times washed up on Dutch beaches. In August 2014, this sea spider was first found alive by recreational divers on the bottom of the Oosterschelde estuary. This finally proved that the species is present here as a native, and has earned a place on our marine fauna list.
