Clip Description

There are 18 different species of penguin, and most of them live in the Southern Hemisphere. These flightless birds have flippers instead of wings. On land they walk upright and waddle. In the water, they are expert swimmers and divers. Some species can reach speeds of up to 15 miles per hour and can torpedo themselves 3 metres out of the water before landing on a sheet of floating ice. 

In this fascinating clip, chinstrap penguins face a long trek and a cliff face covered in slippery, volcanic ash. However, these super swimmers show how well-adapted they are to life on land. We learn that their comical waddle is surprisingly energy-efficient.
