A beach on Gran Canaria’s northern coast has been closed to the public following the sighting of the venomous ‘Blue Dragon’ sea slug. The local authorities in Gáldar have issued warnings after this marine creature, known for its striking blue and grey coloration, was spotted in the waters off Los Dos Roques.
The Blue Dragon, despite its name, is a type of sea slug known for its electric blue and grey colouration. It floats on the surface of the water and carries venom in its extremities, making its sting comparable to that of a jellyfish. The creature, while beautiful, poses a significant threat to swimmers due to its venomous sting. The slug typically inhabits open waters but can occasionally be swept ashore, prompting the current closure.
Painful sting
In response to the sighting, the Gáldar Town Council has urged beachgoers to stay out of the water and to immediately report any further sightings to the lifeguard services. The Council stressed the importance of caution, noting that the Blue Dragon, or Glaucus atlanticus, is capable of delivering a painful sting when it feels threatened.
Authorities have advised that while this species is relatively easy to identify due to its vibrant coloration and surface-floating behavior, swimmers should remain vigilant and avoid contact with the creature.
What is the blue dragon?
The Blue Dragon is a marine invertebrate usually found in tropical and temperate waters. Its sudden appearance in Gran Canaria has raised concerns, and its presence is thought to be linked to climate change, which may be pushing this species into new territories. This is not the first time the blue dragon has been seen in Spanish waters; in 2021, it was also spotted off the coast of Alicante, marking its first recorded appearance in the Mediterranean.
Is the blue dragon dangerous?
Although the Blue Dragon’s sting is not considered extremely dangerous, it can cause itching, burning, swelling, and redness in the affected area. In some cases, individuals may experience more severe reactions such as vomiting, general discomfort, or acute allergic responses. It is important to note that the Blue Dragon only stings if it feels threatened.
