Did you know that:

• Penguins are champion swimmers.
• They spend 75 percent of their lives in water.
• They are birds, but they can't fly. Penguins are classified as birds because they have feathers.

Now you can explore a penguin's world by finding out how they can swim so fast, what they eat, and why people need to protect their habitats. Acclaimed science writer Seymour Simon has teamed up with the Smithsonian Institution to take you on a journey to the Antarctic region for a close-up look at one of nature's most beloved and sociable animals.
