There's a harmless condition called vitiligo, which causes pigmentation disorders and the appearance of white spots on the skin. This occurs when the body's immune system malfunctions and begins to attack its own color-producing cells (melanocytes). Animals with vitiligo develop incredible colors.

Millions of years ago, dinosaurs ruled the Earth; their remains are even found in Antarctica. Some of them are listed in the Guinness Book of Records for their unusual and remarkable size or external features.

Snakes have long frightened and fascinated people, and most of us have a cliched image of a snake, little familiar with the diversity of these creatures in the wild. But among them, there are unique creatures, distinguished by their appearance and behavior, and they have plenty to surprise us with. Over the course of evolution, snakes have learned to fly, climb trees, and lure prey into traps with cunning devices.

For thousands of years, people have tried to domesticate or tame animals, but out of all the diversity of species, only a few have succeeded in making them their faithful helpers: dogs, horses, pigs, cows, chickens, sheep, goats, cats, and turkeys.

The unusual purple frog is a true living fossil, with ancestors dating back 180 million years and outliving even the dinosaurs. The species was discovered quite recently, in 2003, and in 2008, Scienceray host Chan Li Peng included this amphibian in his list of the 20 weirdest and ugliest creatures on the planet.
