Polar bear - "The largest land hunter"
Polar Bears are huge!
Polar bears are some of the most fascinating animals on Earth. They live in the Arctic, where it’s freezing cold, and they have special features that help them survive in such a harsh environment. They are the largest hunters on land. Let’s learn all about these incredible creatures!
How Big Are Polar Bears?
Polar bears are enormous!
• Male polar bears can grow as tall as 10 feet (3 meters) when standing, and they can weigh between 900 and 1,600 pounds (410-720 kg). That’s about as heavy as a car! They can also be 8-10 feet long (2.5-3 meters).
• Female polar bears are smaller. They usually grow to be 7-8 feet long (2.1-2.4 meters) and weigh around 330 to 650 pounds (150-295 kg). Even though they are smaller, they are still very strong!
Where Do Polar Bears Live?
Polar bears live in some of the coldest places on Earth.
They live in the Arctic regions of countries like Canada, Alaska, Russia, Greenland, and Norway. These places are covered in ice, and polar bears spend most of their time on sea ice. They use the ice to hunt for their favorite food—seals.
What Do Polar Bears Eat?
Polar bears are carnivores, which means they eat meat.
• They mainly eat seals, especially ringed and bearded seals. Polar bears love to eat seal blubber because it’s full of fat, which gives them the energy they need to survive in the cold.
Polar Bear Playtime
Even though they are strong and serious hunters, polar bears know how to have fun.
Male polar bears sometimes have playfights with each other. They approach each other with their heads down, gently bite each other’s necks, and try to stand up on their back legs, like sumo wrestlers, trying to push each other over!
Special Features of Polar Bears
1. Black Skin and Clear Fur
You might think polar bears are white, but their fur is actually clear! It looks white because of the way it reflects light. And underneath their fur, they have black skin. This helps them trap heat from the sun to stay warm in the icy cold.
2. Incredible Sense of Smell
Polar bears have an amazing sense of smell. They can smell a seal from 32 km (20 miles) away on the ice! They can even smell a seal when it’s underwater. This superpower helps them find food in the vast, snowy Arctic.
3. Big Claws and Special Feet
Polar bears have huge claws, around 3-4 inches (7-10 cm) long. They use these claws to catch seals through holes in the ice. Their feet are big and covered in thick fur to help them walk easily across the slippery ice without slipping.
Polar Bear Families
• Baby polar bears (called cubs) are born in the winter, in a den where their mom keeps them warm. Cubs are born blind and very small, weighing only about 1 to 1.5 pounds (450-680 grams)!
• Cubs stay with their mom for up to 2.5 years, learning how to swim, hunt, and survive in the wild. Polar bear mothers are very protective of their cubs and take good care of them in the den until they are big enough to go outside.
How Do Polar Bears Sleep?
Polar bears don’t sleep in a bed like us. They usually sleep on the ice or in dens. Female polar bears sometimes make dens to protect their cubs during the coldest months of the year.
Are Polar Bears Endangered?
Polar bears are Vulnerable. This means they are at risk of disappearing from the wild. The biggest threat to polar bears is climate change, which is melting the ice they need to hunt and live on. There are between 22,000 to 31,000 polar bears left in the wild, and that number is slowly decreasing.
Fun Facts
• Polar bears are the largest land carnivores in the world, even bigger than Siberian tigers!
• Their thick fur and fat layer keep them warm, but can also make them too hot if it gets warm outside.
• Polar bears have transparent fur that helps them blend into the snowy landscape so they can stay hidden from their prey and predators.
Polar bears are amazing animals with special abilities that help them survive in the coldest places on Earth. But they need our help to protect their homes and keep them safe from danger!
