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. Pretty amazing when you think these things have been swimming around for so long.
They have hundreds of poisonous tentacles that it used to catch passing by fish. it then slowly drags in it’s prey and eats it.
That is terrifying.
can you imagine if they weren’t as docile as they look in this picture
