British tourists enjoying Spain's sunny coasts are being confronted with an unexpected and dangerous threat – the invasion of venomous 'blue dragon' sea slugs that are washing up on popular beaches.
What Are These Blue Creatures?
The Glaucus atlanticus, commonly known as the blue dragon, is a small but potent sea slug that packs a potentially deadly sting. Despite their beautiful appearance with silver and blue colouring, these creatures are capable of storing venom from their prey, making them dangerous to humans.
Why Are They So Dangerous?
These marine creatures feed on the Portuguese man o'war, absorbing and concentrating its venom. When humans come into contact with them, the sting can cause severe pain, nausea, and in extreme cases, life-threatening reactions. The Spanish authorities have issued urgent warnings to beachgoers to avoid any contact.
Where Have They Been Spotted?
Recent sightings have been reported along several Mediterranean coastal areas popular with British tourists. The unusual phenomenon is believed to be linked to changing sea temperatures and currents, bringing these typically open-water creatures closer to shore.
Expert Advice for Holidaymakers
Marine biologists and local authorities are advising tourists to:
- Avoid touching any unfamiliar marine life
- Keep children away from washed-up specimens
- Seek immediate medical attention if stung
- Report sightings to local beach authorities
Despite their small size – typically no more than 3cm long – these creatures represent a significant health risk to unsuspecting beachgoers. The Spanish tourism authorities are working to monitor the situation while ensuring visitors can still enjoy the country's beautiful coastline safely.
