Polar Bear

About

Polar bears, scientifically known as Ursus maritimus, are the largest land carnivores, thriving in the harsh Arctic environment. They are characterized by their stocky build, long neck, small head, short ears, and short tail. Their fur appears white due to translucent strands that reflect sunlight, while their skin is black to absorb heat. They have large, hairy paws that provide insulation and traction on ice, and sharp claws for hunting and climbing. Polar bears are excellent swimmers, using only their front limbs to propel themselves through water. Polar bears primarily feed on seals, such as ringed and bearded seals, which they hunt by stalking or ambushing at breathing holes. They are solitary animals but can be found in groups during mating seasons. Female polar bears give birth to cubs in winter dens, and the young stay with their mothers for about two years. Polar bears face significant threats from climate change, which reduces their sea ice habitat and access to prey, leading to malnutrition and increased human conflicts. They are classified as vulnerable and are an important indicator species for monitoring climate change impacts.
