• Guardamar del Segura closed its roughly seven-mile coastline on Wednesday after two Glaucus atlanticus were found on Vivers Beach.
• The mayor said a special surveillance operation concluded Thursday with beaches reopened under yellow flags and continued monitoring.
• Local police, lifeguards and municipal crews remain on alert, advising beachgoers to report any sightings and avoid touching specimens, even with gloves.
