Polar bears are the largest land carnivores in the world. Adult males can weigh between 900 to 1,600 pounds (410 to 720 kg) and can measure up to 10 feet (3 meters) in length.

Although polar bear fur appears white, it's actually translucent. Each hair is a clear hollow tube. The fur reflects light, which makes it appear white and provides camouflage in their snowy habitat.
