What Is the Biggest Jellyfish In the World and How Big Does the Lion’s Mane Jellyfish Get?

The Lion’s mane jellyfish, also known as Cyanea capillata, has long golden-yellow streamers of poison cells.

The cold-water jellyfish might resemble a huge lion’s mane, just as Sir Arthur Conan Doyle described it in “The Adventure of the Lion’s Mane”.

Its poison acts like a neurotoxin, and the effect is paralysis.

The average swimmer need not worry about meeting one unawares, however. It is a noticeable and colorful creature.

The bell is at least three or four feet across, and the streamers drag thirty to forty feet.

It does not frequent shallow waters and is most likely found only on the high Seas.
