In the animal kingdom, there's no shortage of creepy, bizarre creatures who crawl on this planet. They range from horned lizards, who shoot blood from their eyes in self-defense to creatures that raise their offspring in the carcasses of dead animals. Some creatures are so bizarre they defy imagination. Komodo dragons use a sixth sense, a 'smell-o-vision' from the roof of their mouth, to seek out prey and cannibal black widow spiders sense movement with their feet. The female preying mantis bites off her mate's head during sex. Hedgehogs will munch on cigarettes and bathe in oil in order to be crossed off the menu for predators.
