It isn’t hard to see where the Lion’s Mane Jellyfish gets its name. Long flowing tentacles surround the bell of the jellyfish, giving it an appearance that resembles the king of the jungle.
Measuring up to 3m in length, these tentacles do pack a painful sting, but generally not a fatal one. But make no mistake: this species is one of the largest jellyfish in the world. Although they’re made of 95% water, the Lion’s Mane Jellyfish can weigh up to 90kg. Each cluster of tentacles contains up to 150 tentacles, meaning one lion’s mane jellyfish can have up to 1,200 individual tentacles. Since they can glow in the dark, this species of jellyfish may just be one of the prettiest too.
