Fun facts about the Penguin
Penguins' wings evolved into flippers over 60 million years of aquatic adaptation. Emperor penguins can dive to depths of 1,800 feet and hold their breath for over 20 minutes. Their black-and-white coloring is a form of camouflage called countershading — dark on top for predators above, white below for those beneath. Penguins have a gland above their eyes that converts saltwater to freshwater.
