The coolest thing about Physalia?  It’s not a jellyfish.  It’s actually a composite organism called a siphonophore, made up of four separate organisms merged together in a colony.  Each different shape of tentacle is literally a different creature, and they work together to feed the whole.
Nature is goddamn amazing.

“The Lions Mane Jellyfish is the largest jellyfish in the world. They have been swimming in arctic waters since before the dinosaurs (over 650 million years ago) and are among some of the oldest surviving species in the world. The largest can come in at about 6 meters and has tentacles over 50 meters long.”

I think I 
Yeah
I never want to see one of those
ever
thanks

Whooooa! I’d love seeing one of those.

ETA: Photoshopped. Yet another fake.
(…Pity.)

WARNING: EXPO IS AN INSUFFERABLE PEDANT ALERT!
Also this is not a Lion’s Mane jellyfish at all.  Those look like this:


They can get to be pretty big, about the size of a large dinner plate or serving tray, and they do have the longest tentacles of any common jellyfish species.
The jellyfish in the OP’s (shopped) photo is a Nomura’s Jellyfish.  They’re common in the waters off of Japan and China—SO common, in fact, that they’re a menace.  


And make no mistake: they can get HUGE



…just, y’know.  Not so huge that they literally dwarf a human being.

Meet Deepstaria enigmatica, a particularly bizarre species of deep sea jellyfish.

They come from Antarctica, which should surprise absolutely no one.

Once again: The Ocean: Proving Lovecraft Right, one Deep-Sea Lifeform at a Time.

More Atolla Wyvillei

…okay correct me if I’m wrong, here, but is that a FUCKING METROID?

The Ocean: Proving Lovecraft right, one deep-sea lifeform at a time.

Deep-sea jellyfish Atolla wyvelli, also known as OH GOD WHAT.  They live in the waters off Japan (of course), and are bioluminescent.

So apparently these guys are called Crown Jellyfish, found in deep water.  What a gorgeous species.  They hardly look real.
