If you've ever seen white snake or koala in nature, you were likely amazed by their beautiful appearances. But, beautiful though they may be, those white animals are actually suffering from a disease: albinism.
Albinism is a congenital disorder that robs the skin, hair and eyes of color. For most animals, skin is functional, protecting against predators and injury. For albino animals, skin is a liability, leaving them vulnerable to sun burn, skin cancer and other health problems. Their bright white skins also make it difficult to hide from predators.
