7. Mongolian Death Worm:
Cleveland, Ohio Mongolia
Turns out the Gobi Desert's good for more than just Tatooine-like landscapes, as it's also allegedly got a Tatooine-like creature in the form of a 5ft-long, deadly-venom-spitting worm.
While you're there: Although the other folks on your bus may frown upon your obsession with the Mongolian Death Worm, don't go the Gobi alone -- book something with Gobi Tours instead. If you want to make it home alive.
