In a very cold part of the world, a penguin stands on the ice. Snow blows around it, but the penguin can stay warm.

Penguins are birds, although they cannot fly. Instead, they are excellent swimmers. They dive into the sea to catch fish and other small sea animals.

Their bodies have special ways to keep warm. They have many feathers that sit close together, and a layer of fat under the skin. Both help protect them from the cold.

Some penguins, such as emperor penguins, also stand close together in large groups. This helps them stay warmer when the wind is strong.

Young penguins need extra care. Their parents help protect them and bring them food until they can do more for themselves.

Life on the ice is difficult, but penguins have bodies and habits that help them survive.
