Leafy Sea Dragon

The Leafy Sea Dragon is one of the few sea creatures with its own built-in camouflage. The tiny fins that are used to propel our leafy friend forward are impossible to see, giving the illusion that you are merely watching some seaweed lazily float by (like an underwater plastic bag à la American Beauty). So the next time you see a chunk of seaweed ... notice the beauty of it, yes. But also notice that you may just be witnessing one of the weirdest sea creatures in the world.
