Giant jellyfish have capsized a 10-tonne fishing boat after its crew tried to haul in a net full of the stinging creatures off the eastern coast of Japan. Dozens of Nomura’s jellyfish sunk the Diasan Shinsho-maru boat and sent its three-man crew into the sea, The Mainichi Daily News reported. The organisms can weigh up to 440lbs and grow up to 6ft in diameter. The three men forced into the sea, near Chosi, were rescued by another trawler. Waters around Japan have been inundated with the jellyfish this year. Experts believe weather and water conditions in the breeding grounds off the coast of China have been ideal for the species in recent months. “The arrival is inevitable,” Hiroshima University Professor Shinichi Ue told the Yomiuri newspaper. “A huge jellyfish typhoon will hit the country.”
What they didn't mention, is that lots of top predators would eat these jelly fish.... if they were still present in decent numbers. Large turtles, ocean sunfish, and large tuna, etc eat jelly fish. Humans do also, I've had them, pickled, was like eating pickle rubber bands.
