1. The Tiny Lives of Polar Bear Cubs
Polar bear cubs are incredibly tiny when they are born, measuring only about 15 inches long and weighing only 1-1.5 pounds - that's about the size of a guinea pig! This is a stark contrast to human babies, which are typically around 20 inches long and weigh 7-8 pounds at birth. Despite their small size, polar bear cubs are born with a thick coat of fur and are able to walk within a few hours of being born.

3. Polar Bears & Brown Bears: Cousins of the Arctic!
The majestic polar bear, a symbol of the Arctic, is closely related to the brown bear. In fact, the two species are so closely related that they can interbreed, producing a hybrid offspring known as a pizzly bear. Polar bears have a thick layer of blubber and fur to keep them warm in the frigid Arctic temperatures, while brown bears have a shorter, less dense coat. Despite their differences, both species share a common ancestor, making them distant cousins.

4. Polar Bears Have Bumpy Feet to Stay Steady
Polar bears have an incredible adaptation to help them stay steady on icy surfaces: their feet are covered with small bumps called papillae. These bumps provide traction and help the bears to keep their footing on slippery surfaces, allowing them to move quickly and confidently across the frozen tundra. Without these bumps, the polar bear would be unable to traverse the icy terrain and would be unable to hunt for food.

The cubs are born blind and helpless, and rely on their mother for protection and nourishment for the first two years of their lives. During this time, the mother bear will fiercely defend her cubs from any potential predators, including other polar bears.

8. How Polar Bears Survive in Their Icy Environment
Polar bears have a unique adaptation that helps them survive in their icy environment: their fur is oily and water repellent. This oily fur helps keep them warm and dry, even when they are swimming in the frigid Arctic waters. The fur is made up of two layers: an outer layer of long guard hairs and an inner layer of short, dense underfur. The guard hairs are hollow, which helps insulate the bear from the cold, while the oily underfur repels water and helps keep the bear dry.

9. Polar Bears: apex predators of the Arctic
Polar bears are apex predators, and their diet primarily consists of seals. They are well adapted to their environment, with thick fur and a layer of fat that helps them survive in the cold Arctic climate. They are also powerful swimmers, able to swim for long distances in search of their prey. Seals are their main source of food, and they will also eat other marine mammals, such as walruses, and scavenge for carcasses of whales and other animals.

10. Polar Bears: The True Colors of a Rare and Mysterious Species
Contrary to popular belief, polar bears are not actually white - their fur is actually made up of transparent hairs that reflect the light, giving them the appearance of being white. Each individual hair is hollow, allowing it to act like a fiber-optic cable, reflecting the light that passes through it and giving the bear its iconic white color. This unique fur helps the polar bear to blend in with its icy environment, providing camouflage from predators and helping it to hunt for food.
