One-in-a-Zillion All-Black Penguin

An all-black penguin has been snapped in Antarctica by a National Geographic photographer. Scientists say the mutation from the typical tuxedo markings is unbelievably rare, essentially one in a zillion. The photographer said the New York-ready bird appeared to be assimilated and had a black-and-white mate. About one in every 250,000 penguins are partially black, but no other all-black ones are known to exist.
