A marine giant is found and Craig McClain is to the rescue to dispel myth from fact!

Have you seen this picture? Apparently it’s been floating around on the internet for a while now, but has experienced something of a comeback as of late, usually with some version of the following caption:

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.

Well, I hate to break it to you guys, but you’ve been deceived (on the Internet, of all places). Over on Deep Sea News, Craig McClain gives a good rundown of why this photo is clearly a lie
