Tourists have been banned from going into the water along an entire seven-mile stretch of Spain’s Costa Blanca because of rare sea creatures with a potentially-fatal sting. The dazzling blue creatures absorbs the stinging cells from its food and stores them in concentrated doses, giving it a far more potent sting than its prey. Typical symptoms of the blue dragon’s sting include nausea, pain, vomiting and acute allergic contact dermatitis.Vivers Beach, a natural stretch of coast south of the Segura River and north of La Babilonia Beach, was said to be full of people yesterday although less people than normal were in the sea defying the bathing ban order and risking heavy fines. Are oceans safe for humans because of myterious creatures in them?
