Venomous Blue Dragon Sea Slugs Prompt New Beach Closures on Costa Blanca

Several beaches along Spain’s picturesque Costa Blanca have recently been closed to the public following the appearance of the rare and venomous blue dragon sea slugs. This small but formidable marine creature, distinguished by its vibrant blue and spiky appearance, poses serious risks to swimmers and beachgoers.

What Exactly Are Blue Dragons?

The blue dragon, scientifically known as Glaucus atlanticus, is a tiny sea slug, measuring about an inch and a half long. Despite its size, it carries a powerful sting capable of causing severe pain and other unpleasant symptoms. These creatures feed on venomous prey such as the Portuguese man o’ war and store their prey’s stinging cells, making their own sting even more potent.

The Scale of Recent Closures

Authorities have already cordoned off a seven-mile stretch in the Cuevas del Almanzora region, extending the ban to three additional beaches: Cala Verde, el Playazo, och Cala Siret. Red warning flags signal these closures, informing both tourists and locals to refrain from swimming and beach activities at these locations.

Closed Beaches Plats Warning Signal Risk Level
Cala Verde Villaricos, Costa Blanca Red Flag High (Bathing banned)
el Playazo Villaricos, Costa Blanca Red Flag High (Bathing banned)
Cala Siret Villaricos, Costa Blanca Red Flag High (Bathing banned)
Other beaches in Cuevas del Almanzora Nearby Yellow Flag Precautionary

Precautions and Public Safety Advice

Local town officials and Civil Protection officers urge visitors and residents alike to avoid any contact with blue dragons, emphasizing that even gloves do not guarantee safety from their venom. In the case of a sting, affected individuals should remain calm and avoid using freshwater on the wound, as this can worsen symptoms.

  • Do not touch blue dragons under any circumstances.
  • Report any sightings immediately to local authorities.
  • If stung, avoid freshwater; seek medical advice promptly.

Symptoms Associated with Blue Dragon Stings

The sting typically causes intense pain, described by victims as similar to a strong jellyfish sting, accompanied by nausea, vomiting, and allergic skin reactions such as contact dermatitis.

Why Are Blue Dragons Increasingly Present on These Shores?

Though usually found in warmer, tropical waters, scientists suggest that climate change and warming sea temperatures are moving blue dragons further north along the Spanish coast. Their presence often signals ecological shifts in marine environments, as they follow the distribution of their prey.

Past Incidents and Responses

Similar beach closures occurred recently further north along the Costa Blanca, affecting the popular tourist area of Guardamar del Segura near Torrevieja. Authorities acted swiftly in those cases after multiple sightings, reflecting a cautious approach to public safety due to the blue dragon’s venomous threat.

Mayors and local officials emphasize the heightened risk these creatures pose, especially to small children, the elderly, and those with pre-existing health conditions, who may experience more severe reactions.
