Today is Penguin Awareness Day, a day to learn a little bit more about these flightless birds of the south. One interesting fact about penguins is why they are colored the way they are (dark/black back and bright/white belly). Its because they spend nearly 3/4 of their time in the water and is for camouflage. From above, their dark back helps them blend into the depths below and from below their bright belly helps them blend with the light from above.
