Blue Dragons Prompt Beach Closures and Safety Warnings

Authorities in Lanzarote were compelled to close a beach due to the presence of dangerous marine life. Lifeguards evacuated La Cantería beach in Órzola after sightings of blue dragons. These sea slugs, though visually striking with their metallic blue and silver coloration, are highly poisonous. Contact with them can lead to serious health issues.

The blue dragon, scientifically known as Glaucus atlanticus, preys on venomous jellyfish, such as the Portuguese man o’ war, and accumulates their toxins. A sting from a blue dragon can cause significant pain, skin irritation, vomiting, fever, and potentially more severe allergic reactions.

These sea slugs typically reside on the ocean floor. However, they can float on the surface by swallowing a small air bubble. Measuring around 3cm in length, these ornate creatures are found in the Atlantic, Pacific, and Indian Oceans. This summer, blue dragons have been observed in the waters surrounding the Canary Islands. Recent sea conditions, including wind and currents, have transported them to various locations along the Lanzarote coastline. They were also recently seen at El Médano and Leocadio Machado beaches in Tenerife, prompting warnings from local authorities.

Swimming was prohibited along a seven-mile stretch of coast near Guardamar del Segura on the Costa Blanca last Wednesday. The mayor of Guardamar del Segura announced the ban following the appearance of blue dragons on Vivers Beach. If stung by a blue dragon, the affected area should be rinsed with seawater, and any tentacle fragments should be removed using a stick or gloves. A cold pack can help reduce swelling. Medical attention should be sought if breathing difficulties, dizziness, or a severe allergic reaction occur.
