Be amazed

- [Narrator] Remember when you used to draw animals as a kid using whatever crayons you had to hand? You probably created ridiculous things like purple polar bears, bright-yellow parrots, white lions and pink grasshoppers, but what if I told you all those things aren't as made-up as you might think? The animal kingdom is far more than you know, and coming up are some of the world's rarest creatures that definitely won the genetic lottery. (bright upbeat music) Melanistic Fox. When you think of the world's most beautiful wild animals, foxes probably don't spring to mind, but have you ever seen one like this before? This is the incredibly rare and majestic cross fox, which was once abundant in America until they were largely killed off in the late 19th century thanks to high demand for their unique fur. Cross foxes are almost identical to red foxes, but they have a larger, bushier tail with more wool under their feet. The cross fox was given its name thanks to the long, dark stripe running down its back, intersecting another stripe to form a cross over the shoulders. Their incredibly unique coat is the result of a partially-melanistic variant. Melanistic is basically the opposite of albinism, meaning that an abundance of dark- pigment is produced under the skin. Although melanistic foxes make up about 30% of the Canadian fox population, they're still a very rare sight to see, but there's an even more elusive kind; the silver fox. These mysterious foxes are a fully melanistic version of the cross fox created through years of breeding. As you can see, they have a glossy black undercoat with a topcoat that looks like they've been dusted with silver, as well as some white on the tip of their tails! One thing's for sure: you'd be incredibly lucky to see one of these foxes raiding your bins! King Cheetah. Notice anything out of the ordinary about this cheetah? Take a closer look at that magnificent coat when compared with its run-of-the-mill counterpart, and you'll see what makes them to behave as they does.
