Even the animals that are most familiar to us have a huge diversity of appearances. A pug is a very different-looking creature than a German shepherd, and a Siamese cat could not look more different than a Persian. But when you remove their fur, they look even stranger. Any mammal without its hair looks like an alien, and the beasties on this list are the most bizarre among them.

She lived at the Cincinatti zoo until she died unexpectedly of a cold in 2009.
