Japanese fishermen are preparing for the arrival of a swarm of humongous jellyfish. Known as “Nomura’s” jellyfish, these large sea creatures can grow to be 6-feet long and weigh 450 pounds. Ocean currents are carrying them into the Sea of Japan, where the jellyfish tear holes in fishing nets, devastating the local economy.
Similar swarms arrived in Japan in 2005 and 2007. Japan now has a system of warning fishermen about the jellyfish, a method that may cost the seamen a big catch, but one that will save their expensive nets.
