Spain: Beach Closed Due to Sighting of 'Blue Dragons'

An alert has been issued in Costa Blanca, Spain, following the appearance of rare and dangerous sea creatures known as 'blue dragons' (Glaucus atlanticus). Municipal authorities in Guardamar del Segura have temporarily banned swimming along an 11-kilometer stretch of coastline, raising black flags for safety reasons.

The ban was implemented after two 'blue dragons' were found on Vivers beach. Mayor José Luis Sáez warned citizens to avoid contact with the creatures, emphasizing the danger despite their small size (up to 3 centimeters). If contact occurs, washing with seawater and seeking medical help is advised.

The town hall has launched a preventive search operation. Local police and lifeguards are on alert. Several vacationers ignored the recommendations and risk fines.

The 'blue sea dragon' (Glaucus atlanticus) is a nudibranch with a potent venom. Contact causes pain, nausea, vomiting, and dizziness, and can lead to allergic reactions.

'Blue dragons' are mainly found in tropical waters, but are occasionally spotted in Europe. Their appearance on the Costa Blanca is considered rare.

Spanish authorities advise people not to approach the creatures and to immediately notify lifeguards if sighted.
