The Lion's Mane Jellyfish, the largest jellyfish in the world

Anyone else reminded of Spongebob?

Is that the one from one of Arthur Conan Doyle's short stories? I think it is, when Sherlock and Watson find mutilated people and then find out it was the doing of this jellyfish, but nobody could see it cause its tentacles are so clear they're almost invisible.

He's just taking a photo so chilled

I would have a heart attack and die

I wanna touch it...
