The World's Weirdest Tongues

Tongues are quite handy across the animal kingdom. They give an animal control over what goes in its mouth, and humans have learned to use theirs for communication. Other creatures have specialized tongues that do some amazing -and weird- things. When I saw the title to this video, the first tongue I thought of was the woodpecker's. It's here, along with snakes that can smell in stereo with their tongues, and predators with tongues as weapons.
