Japan may be invaded by giant jellyfish again this year. Nomura’s jellyfish can be bigger than humans (up to 440 pounds, or 200 kilograms), and they’re big trouble for people fishing on the coasts. Nomura’s jellyfish breed in the waters off of the coast of China. From there they move to the coasts of Japan. The jellies clog nets and ruin potential catches with their toxic stings. This damage can cost the coastal fishers billions of yen.
Researchers at Hiroshima University have been monitoring sites where Nomura’s jellyfish breed, and they’ve found large numbers of the jellies, meaning that a new invasion may not be far away.
