What is the biggest jellyfish in the world?

A Giant phantom jellyfish
B Lion’s mane jellyfish
C Australian box jellyfish

On average, lion’s mane jellyfish are a modest 1.5 feet in length. However, in some cases their bodies (or ‘bells’) can reach up to 8 feet wide, and their tentacles can stretch up to 120 feet. They are often found in the Irish Sea, the English Channel, and the North Sea but have also been seen in the Gulf of Mexico.

The correct answer is Lion’s mane jellyfish.
