The Dutch Province of Zealand maintains its alert concerning the presence of brown cross jellyfish (Gonionemus Vertens) in the swimming area of Grevelingendam, she announced on Thursday. France is also confronted with an increase in accidents related to the presence of a kind of jellyfish, physalies (physalia physical).
No lively brunette cross jellyfish had been spotted last week and the authorities of the Dutch province therefore planned to lift the alert, but new specimens of this very stinging species were identified in the area at the start of the week. “”The alert therefore remains in force for the moment“Said the province of Zealand.”The situation will be reassessed next week.”
At the end of June, many bathers who had immersed themselves in the waters near Grevelingendam were victims of strong symptoms and some even had to be hospitalized. Initially these injuries were attributed to Scorpion fish, a kind of poisonous fish, but it was finally proven that they were the work of brown cross jellyfish.
