Its Jellyfish Day! So grab your... umm... so head on down to... er... hm. Okay, so we have no idea how you might celebrate Jellyfish Day. But you can start with this gorgeous gallery of the often deadly creatures prepared for us by the leaders in all things natural, National Geographic. 

We think a photo gallery is only appropriate, since many jellyfish have a sting that is not only incredibly painful, but can kill quickly. So look, but please don't touch!
