As many species of penguin live in cold climates it’s important that they are able to survive the difficult winters. Because of this, their bodies have adapted amazingly well to provide this level of safety. For example, although they are flightless birds they are excellent swimmers due to their webbed feet and streamlined bodies. Their wings are also shaped like flippers to help reach such fast speeds under the water.
To stay warm their bodies have very thick skin and lots of fat (also known as blubber!). To keep temperatures up as a group penguins will huddle together in large numbers. Lastly, the black feathers of the penguin allow them to better absorb the sun’s heat.
