The Vega Baja coast has drawn attention this weekend with the unexpected appearance of numerous blue dragons, scientifically known as Glaucus atlanticus. These small but vibrant marine invertebrates were first spotted at La Mata beach in Torrevieja and have since been reported in several locations in Guardamar del Segura. In Torrevieja, a yellow flag is currently flying, although this is due to the presence of jellyfish rather than the blue dragons themselves.

Presently, there have been no reported incidents or stings, but it is recommended that both locals and tourists exercise caution. The blue dragon is a mollusc that measures just a few centimetres in length and floats on the surface thanks to an air sac in its body. Its silver body, electric blue tones, and fantastical shapes have captivated onlookers, but these stunning creatures are known to deliver painful stings that can be particularly harmful to children, the elderly, or those with sensitive skin.

The severity of the sting largely depends on their diet, as these invertebrates feed on jellyfish and other stinging organisms, storing the stinging cells of their prey within themselves. Fortunately, in the beaches of Guardamar and Torrevieja, only blue dragons have been found, with no presence of the feared Portuguese man o’ war, which can cause more harmful effects.

The increasing sightings of blue dragons along the Vega Baja coastline may be linked to changes in sea currents and water temperatures. Experts indicate that it is common for oceanic species to be washed ashore at certain times of the year, making each sighting both a fascinating and concerning phenomenon. Although there is currently no significant threat posed by the blue dragons, beach lifeguards and monitoring services recommend that individuals avoid touching any specimens found on the sand or approaching the shore, as even in an inactive state, they can cause skin reactions. The arrival of these unusual sea creatures has intrigued bathers, who have not hesitated to take and share photographs on social media, reminding everyone that the Mediterranean harbours both natural treasures and, at times, potential dangers.
