José Luis Sáez, the mayor of Guardamar del Segura,announced on Xthat swimming was prohibited following "the appearance on Vivers Beach of two specimens of Glaucus atlanticus, known as the Blue Dragon." The beaches of Guardamar del Segura span seven miles, perSky News. With his announcement, Sáez added two photos of the blue dragons, which are typically about four centimeters in length. They are known to be foraging predators with tentacles that hold highly poisonous stinging cells, used for both hunting and self-defense, explains theBureau of Ocean Energy Management. Policía Local Guardamar/Facebook Sáez warned residents not to touch the slithering creatures, even with gloves. "Notify lifeguards or authorities. If stung, rinse with salt water and go to a first aid station or health center. These are poisonous specimens, and their bite causes nausea, pain, and vomiting," he said. Sáez said that the Guardamar City Council has implemented a preventive measure to detect possible specimens swept away by ocean currents. The presence of the sloths, though, caused the local police in Guardamar del Segura toissue their own warning. "Contact with this marine animal can be dangerous and cause painful skin burns. We ask residents and visitors to follow the instructions, exercise extreme caution, and avoid direct contact with specimens that may appear on the sand," their statement said in part. The notice advised that they, in coordination with municipal services, were going to maintain surveillance and "provide prompt information on the development of the situation."
