Sunday, September 28th, 2014

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.

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.

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.

Seahorse in the Oosterschelde (Netherlands)

During a night dive at the Bergse diepsluis I had a short but very special experience with this at least 15 cm [long] seahorse. In the light of my buddy (Rene Weterings)’s dive light I suddenly saw the silhouette appear. After about 15 minutes he was gone in the night just as quickly as he came. Unfortunately, the seahorse apparently is moving and we have [not] seen him anymore.

This is a short-snouted seahorse.
