Lion's mane jellyfish

The lion's mane jellyfish (Cyanea capillata) is one of the largest jellyfish species in the world.[1] Most live in north Atlantic and north Pacific waters, but some live as far south as the Gulf of Mexico.[2] Their stings are painful, but not fatal.[3]

They are also known as Hair Jelly and Sea Blubber.[4] They usually do not live for more than one year.[5]

A group of jellyfish is called a smack.[6]

The pileus ("bell") of the lion's mane jellyfish can be up to 2.4 meters (8 feet) wide.[3] Hanging off the 'bell' are up to 1,200 tentacles divided into eight sets.[1]

The largest lion's mane jellyfish ever found was 36.5 meters (120 feet) long.[2]
