Dangerous sea slugs have forced the closure of a popular stretch of coast following multiple sightings of the pair of alien-like creatures, which can “burn” human skin. Swimming has been banned across Guardamar del Segura, on the Costa Blanca in southeastern Spain. Local police say, “Due to the massive appearance of the Blue Dragon (Glaucus atlanticus), and for citizen safety reasons, SWIMMING is PROHIBITED on all beaches of the municipality until further notice.” Informally known as the blue dragon because of their likeness to the fantasy creature, they measure around 1.2 inches long. “Contact with this sea animal can be dangerous and cause painful burns on the skin,” police said. According to CNN, they feed on other venomous creatures, using their own poison to put creatures even 300 times their size at risk of paralysis. Tourists have also been warned to adhere to the notice. Policía Local Guardamar added, “We urge neighbors and visitors to respect the directions, exercise caution, and avoid direct contact with specimens that may appear in the sand.”
