The Lion's Mane Jellyfish (Cyanea capillata) is considered to be the world's largest species of jellyfish. Also often is cited Cyanea arctica, but is most likely to be subspecies or variety. The biggest recorded specimen had a bell with a diameter of 2.3 m (7 feet 6 inches) and the tentacles reached 36.5 m (120 feet).


Nomura's jellyfish (Nemopilema nomurai ) is one of the largest species of jellyfish. It lives near to Japan and is known in Japanese as echizen kurage. They are growing up to 2m (6 ft 7 inches) in diameter and weighting up to 200kg (440 lb).
