Polar Bears: Life on the Ice
Polar bears live in the Arctic. It is a cold place. Ice floats in the water. There are no trees. How do polar bears stay warm? They have adapted to the cold.
What They Look Like
Polar bears are giant, or very large. Males grow up to 1,700 pounds. They can be 10 feet tall. They may live 25 years.
Their fur has no color. It looks white in the snow. Fur is thick hair. It grows on skin.
They have black skin. Their skin soaks up the Sun’s rays. This helps warm them.
Fat traps heat. Polar bears have a lot of fat. It helps them stay warm, too.
Why They Hunt
Cubs are born in dens. Dens are warm. Their mother cares for them. She protects them for 28 months. They learn to hunt.
They hunt seals. Seals go under the sea ice. They come up for air. Polar bears wait on the sea ice. Then they grab the seals.
Polar bears eat what they want. No one can compete with them.
It is still hard to find food, though. Arctic water is warming up. Sea ice melts too soon. Polar bears do not have time to hunt. They swim to find more sea ice. They go far from home.
