The penguin body is well suited to swimming in water. Their wings act as flippers, and they
stay buoyant by trapping air in their feathers.
On land, however, our tuxedoed friends travel much more awkwardly. They usually waddle upright on
their feet, using their wings and tail for balance. For short bursts of speed, they sometimes jump
with both feet together.
A more amusing way of getting around is called "tobogganing," where penguins slide on
their bellies. They can sled downhill or use their feet to push them across level terrain.
