Beaches shut down due to the appearance of seldom-seen blue dragons, dubbed 'angels,' causing alarm

In a recent statement, the mayor of Guardamar del Segura, José Luis Sáez, has asked residents and visitors to exercise extreme caution when visiting the beach. The cause for concern? Tiny, cutesy-looking creatures known as blue angels, which have been sighted in the Mediterranean, causing the closure of beaches across Spain.

These blue angels, with their silver-grey bellies and bright blue streaks, may seem harmless, but they are venomous. They absorb stinging cells from their prey, specifically jellyfish-like species like the Portuguese Man O' War, and store them in their finger-like appendages, effectively turning them into floating stingers.

A brush with a blue angel can result in symptoms such as vomiting, redness and inflammation, pain, and nausea. The mayor's statement does not provide updates on the symptoms or treatment for a brush with a blue dragon, but he has urged people to follow the advice of the Local Police.

The Local Police of Guardamar del Segura have issued a warning about public safety, prohibiting swimming at all beaches in the area until further notice. They are monitoring the situation closely and will provide updates as it evolves. The mayor has reinforced these warnings, noting an increase in the frequency and number of blue dragons on the beaches of Guardamar.

The mayor's statement does not provide new information about the characteristics, behavior, or effects of the blue dragons, but it does serve as a reminder to be very cautious when walking along the shore. He has also asked people to avoid direct contact with any blue angels that may appear on the sand.

This is not the first time blue dragons, or Glaucus atlanticus, have been spotted on Spain's Mediterranean beaches. Sightings notably began at least by May 2025 near Mallorca and intensified with several sightings near Guardamar del Segura on August 20, 2025, leading to beach closures along the Costa Blanca.

The mayor's statement marks the latest update from the mayor of Guardamar del Segura. He has used the term "RED FLAG" in his statement, indicating the seriousness of the situation. He has also advised people to be very cautious when walking along the shore, echoing the Local Police's warnings and prohibitions regarding the blue dragons.

As the situation continues to develop, it is crucial for everyone to follow the instructions and exercise extreme caution when visiting the beach. The Local Police and municipal services will provide updates as the situation evolves.
