The North Sea has not exactly been considered a seahorse sea. But more and more rare seahorses are being discovered in Lower Saxony, and now there is also a find in the Wadden Sea in Schleswig-Holstein. The finds are a mystery.
Seahorses typically prefer tropical, subtropical, and temperate latitudes. According to the nature conservation organization WWF, they have been increasingly discovered on the beaches in the Wadden Sea since 2020. "Ultimately, we don't know what the reasons for this are," said Hans-Ulrich Rösner, head of the WWF Wadden Sea office in Husum. "Whether there are more seahorses elsewhere that are carried into the Wadden Sea by currents, or whether there is a local population living in the Wadden Sea."
Together with the project partners, the WWF now wants to expand the call to include the northernmost federal state. Because: “A seahorse was also found in Schleswig-Holstein at the end of September,” said Rösner. It was discovered in the Wadden Sea area between Pellworm and Hooge. That is very rare, emphasized the 64-year-old.
On the online platform Beachexplorer.org, walkers can enter their finds on the beach and upload photos. In the first half of this year alone, around 30 living or dead seahorses were discovered, Rösner reported. "That stands out compared to the past." A total of 60 finds are entered on the platform - also from the Netherlands or Denmark.
According to the WWF, anyone who finds a dead seahorse on the North Sea coast should take a photo and ideally place a euro coin next to it as a scale so that the size of the animal can be determined. "We hope for support from the public," emphasized Rösner. "We are quite curious if more seahorses will be seen now."
