The polar bear, also known as the "ice bear," is a large marine mammal native to the Arctic region. These majestic bears are known for their distinct white fur, powerful forelimbs for swimming, and specialized adaptations for living in a cold and icy environment. Polar bears are expert hunters, primarily preying on seals, and are well adapted to their icy habitat. They are considered a threatened species due to the loss of sea ice caused by climate change, which is leading to reduced access to their primary prey and habitat degradation. Conservation efforts are critical to ensuring the survival of these iconic Arctic predators.
