Sure, penguins can dive to great depths, and have all the grace and agility of ballet dancers when swimming. But it is the way they carry themselves on land that so endears them to us—they waddle. Collected here are dozens of color photos of these beloved birds, with appreciative comments by Ernest Shackleton, Douglas Adams, Edgar Allan Poe, Roald Amundsen, Tim Burton, Diane Ackerman, and Benedict Cumberbatch.
