Beaches closed over blue dragon sting

Authorities closed a seven mile stretch of the Costa Blanca after two blue dragon sea slugs were spotted, citing the risk of a painful sting.

Coastal Spain closes beaches after blue dragon sighting

Authorities closed a seven-mile section of the Costa Blanca around Guardamar del Segura after two Glaucus atlanticus specimens, known as the blue dragon, were spotted on Vivers Beach. Local mayor Jose Luis Saez posted on X that bathing is prohibited because of the animal’s sting and urged people to stay away.

Blue dragons are sea slugs that feed on Portuguese man o war and store its stinging cells, making their own sting potent. The creatures typically float near the surface and can be blown ashore by winds, which helps explain why more have appeared along the coast and why beach safety remains a moving target.

The incident shows how coastal safety relies on quick communication and a willingness to pause leisure for precaution. Officials must balance public safety with the needs of a tourism-driven region, and mixed messages can sow confusion among visitors.

Looking ahead, the episode underscores the need for clear, current guidance and reliable information. As marine life shifts with wind and weather, authorities should provide precise thresholds for openings and closures to avoid empty beaches and disappointed tourists.

Highlights

Coastal watchers will wait for the next update from authorities as the sea keeps its own schedule.
