* Vast number: Polar bears have millions of hairs on their body. Each hair is hollow and acts as a tiny insulator, trapping heat and keeping the bear warm in frigid Arctic conditions.
* Variation: The number of hairs can vary depending on the individual bear's size, age, and overall health.
* Shedding: Polar bears shed their fur seasonally, so the number of hairs constantly changes.
Instead of focusing on the exact number, it's more important to understand the significance of their dense fur coat for survival.
