Jellyfish are wreaking havoc on tourist areas

Jellyfish blooms are on the rise and taking over the ocean, experts say. They may not look scary, but they pose a serious threat to regions that are just now entering their tourism seasons.
A horde of jellyfish forced the shutdown of a nuclear power plant in Sweden earlier this month after they clogged the filtration system. Fishing boats in Japan have been capsized by refrigerator-sized Nomura jellyfish becoming caught in nets. And just last week, swarms of poisonous box jellyfish – which have historically been limited to Southeast Asia and Australia – stung nearly 200 people along Florida’s Daytona Beach.
