The world's largest jellyfish, the venom of the Nomura, can grow up to 2 meters in diameter and weight up to 200 kilograms. Fishermen in Wakasa Bay in Japan are angry because such a creature can easily ruin a whole day's catch by killing fish when they get ensnared with them in the nets. Some fishermen have stopped fishing because seeing jellyfish in your nets is very depressing. This year the jellyfish swarm is really the worst. Giant jellyfish used to be a rarity occurring every 40 years, but now they are almost annual occurrence along Japanese coast which is thousands kilometers long. Scientist believe that climate change is the reason of increased occurrence of th! e giant jellyfish close to the ocean coasts. The warming of oceans made almost 2 thousands jellyfish species to move. Jellyfish are blamed for destroying fishing industries in Japan and terrorizing swimmers worldwide. A study held in 2008 says that 500,000 people are stung every year and 20 to 40 die each year in the Philippines from jellyfish stings. In 2007, the mauve stinger, a jellyfish normally living in warm Mediterranean waters, attacked a salmon farm in Norther Ireland and killed more than 100 thousands fish. The climate change allowed the jellyfish to migrate. Highly polluted waters – for example off China – caused growth of the plankton which is good nutrition for jellyfish, but overfishing eliminated many of the jellyfish's predators. Scientists say increased occurrence of jellyfish is a clear evidence of global warming and it is also a warning sign that our oceans are unhealthy.
