Jellyfish get a bad rap because of the whole stinging thing. But pain and irritation aside, they can be pretty awesome. If you want proof, just take a look at this swim through Jellyfish Lake in Palau, an island part of Micronesia. The delicate way they shuttle through the water is mesmerizing. Their color is sublime. And their sheer quantity is staggering. Wear a body suit, though, because these babies hurt.
