Many people think that penguins live in the places where it is very cold. But we can find them not only along the Antarctictic continent (not the Arctic!) and islands. They also live in Peru, Brazil, Southwest Africa, New Zealand and the south of Australia.
The penguin is famous it can stand up straight and walk. When they walk they look funny to us. They look like people wearing black coats and white shirts.
Ages ago, the penguins were about 2 metres tall and could fly as well as any other bird. But today their wings are short and useless for flying. How did it happen? Many scientists say that it happened because penguins had very enemies. They lived on the territories where there was practically nobody dangerous for them. So they could safely spend all the time those wings became very small, until today they are useless for flying. But penguins are fantastic swimming. Penguins also developed a thick coat of fat to protect them from the ice cold of the territories where they live.
