There's no denying that penguins are seriously cute, and the flightless birdie has some pretty unique characteristics, too. Not only can they stay underwater for 20 minutes at a time, but penguins live and thrive in frigid temperatures. Celebrate everything penguin on Jan. 20, which happens to be Penguin Awareness Day, with this collection of interesting facts paired with adorable penguin-filled pictures. You'll be amazed at how smart, special, and silly these birds are!
