Jellyfish invasion clears beaches across Spain
Holidaymakers have been banned from swimming at beaches across Spain amid what is expected to be the worst jellyfish invasion for two years.
Several beaches on the Costa Blanca, north of Alicante, were closed to bathers after swarms of the mauve stinger jellyfish plagued the beaches of the Mediterranean.
The tentacles of the bright purple creatures, which emit a yellow glow at night, deliver mild stings but can cause severe allergic reactions in some people, even leading to heart failure.
The Red Cross treated 50 people for stings in half an hour at a beach in Denia, a resort on Spain's eastern Mediterranean coast.
Meanwhile, on Spain's northern Atlantic coast, nine beaches were closed over the weekend after the potentially deadly Portuguese man o'war jellyfish was spotted off Asturias. (© Daily Telegraph, London)
