The largest jellyfish in the world?Description:
There is some confusion as to which jellyfish is the larges in the world the two candidates being Nemopilema nomurai or Nomura's jellyfish and Cyanea capitata or the Lion's mane jellyfish. Nomura's jellyfish has a larger mass, while the lion's mane jellyfish is longer. Of these two features I would be more inclined to give the award to Nomura's jellyfish. It can group up to 2m in diameter and can weight up to 200kg.
Nemopilema nomurai lives in the west pacific.
