Many people think that all penguins live in very cold places, but that is not true. Some penguins live on warm beaches in Africa and South America. However, the emperor penguin lives in Antarctica, one of the coldest places on Earth. How does it stay warm?
First, penguins have a thick layer of fat under their skin. This fat works like a warm blanket. Penguins also have many short feathers that are very close together. The feathers keep the cold air and the cold water away from their bodies.
Penguins also take care of their feathers. They spread a special oil on them with their beaks. The oil helps the feathers stay dry in the sea.
When the weather is very bad, emperor penguins stand together in a big group. The penguins in the middle are warm, and the penguins on the outside are cold. So they move slowly and take turns. This way, every penguin gets a chance to be in the warm middle.
