Overview

• Guardamar del Segura reimposed red flags on Sunday after new Glaucus atlanticus specimens were found, keeping bathing prohibited as surveillance continues.
• Five specimens detected on Friday—four at Ortigues and one at Centro—triggered closures, beaches briefly reopened under yellow on Saturday, and were shut again after fresh finds.
• Municipal teams including lifeguards, police and environmental services remain on active patrols and ask residents not to touch the animals, not even with gloves, and to alert authorities.
• Torrevieja reported three to four moribund specimens on La Mata beach with no confirmed stings, noting Monday’s red flag there was due to sea conditions rather than the molluscs.
• Closures and alerts have also been reported in Cádiz, Valencia, Lanzarote and Gran Canaria, and guidance stresses rinsing stings with seawater, applying cold packs and seeking medical care.
