Dangerous ‘blue dragon’ forces beach closure in Lanzarote
La Cantería beach in Órzola, Lanzarote, was temporarily closed this week after lifeguards and bathers reported sightings of several blue dragons (Glaucus atlanticus), a striking but highly dangerous species of sea creature.
Although tiny and beautiful with their metallic blue and silver colours, these creatures are far from harmless. Experts warn that touching them, even if they appear dead on the sand, can cause serious health problems.
The blue dragon feeds on venomous jellyfish, such as the Portuguese man o’ war, and stores their toxins in its own body. This means that a single sting can cause severe pain, skin irritation, vomiting, fever, and, in some cases, more serious allergic reactions.
This is not the first time the species has been spotted in the Canary Islands. In recent weeks, conditions at sea – including winds and currents – have carried them onto various parts of the Lanzarote coastline. They were also recently reported in El Médano and Leocadio Machado beaches in Tenerife, prompting warnings from local authorities.
Authorities strongly advise the public not to touch these creatures under any circumstances, whether in the water or stranded on the shore. Instead, beachgoers should notify lifeguards or emergency services so that the animals can be safely removed.
Safety advice if you encounter a blue dragon
- Do not touch it, even if it looks dead or washed up.
- Alert lifeguards or call 112 (the emergency number in Spain and the Canary Islands).
- If stung:
- Rinse the affected area with seawater (not fresh water, vinegar, or alcohol, which can worsen the sting).
- Carefully remove any tentacle fragments with a stick or gloves, never with bare hands.
- Apply a cold pack (wrapped in cloth) to reduce pain and swelling.
- Seek medical attention immediately, especially if you experience breathing difficulties, dizziness, or a severe allergic reaction.
