No Brain...no heart...no lungs... and they're taking over. No, this isn't a Stephen King tale of horror, but it's no less scary. In the early fall of 2007 billions of jellyfish attacked a salmon farm in Northern Ireland destroying more than 100,000 fish. In Japan, the number of jellyfish has risen so dramatically they are devastating the livelihoods of fishermen. Mass jellyfish sightings are now common along the Mediterranean coast, off southern Africa, the west coasts of England, Wales and Scotland, the beaches of Waikiki, and the Gulf of Mexico.
These giant jellyfish can grow up to 2 meters (6 ft 7 in) in diameter and weigh up to 200 kg (440 lb). And, they pack a wallop. Over 19,000 stings were reported in the Mediterranean last summer including resorts in Italy and France. Twelve thousand pounds of jellyfish were scooped up in three days off the Costa Tropical last year.
