King Penguins are notorious for their prim, tuxedoed appearance -- but a recently discovered all-black penguin seems unafraid to defy convention. In what has been described as a "one in a zillion kind of mutation," biologists say that the animal has lost control of its pigmentation, an occurrence that is extremely rare. Other than the penguin's monochromatic outfit, the animal appears to be perfectly healthy.
The "under-dressed" penguin was photographed by Andrew Evans (of National Geographic) on the island of South Georgia near Antarctica.
