Jegesmedvék, also known as polar bears (Ursus maritimus), are large marine mammals that inhabit the Arctic regions. They are the world's largest land carnivores and are apex predators, playing a crucial role in the Arctic ecosystem. Their thick fur and blubber layer provide excellent insulation against the extreme cold.

Polar bears are characterized by their white fur, which actually consists of transparent, hollow hairs that reflect visible light, making them appear white. They have black skin underneath, which helps absorb solar heat. Their paws are large and broad, with rough pads and non-retractable claws, enabling them to walk on ice and snow and swim effectively.

Their diet primarily consists of seals, which they hunt on the sea ice. Polar bears are skilled swimmers and can travel long distances in the water. They are solitary animals, except during mating season or when females are raising cubs. Females typically give birth to one to three cubs in snow dens dug into the snowdrifts.

The conservation status of polar bears is a significant concern. Climate change, particularly the loss of Arctic sea ice, is the primary threat to their survival. Reduced sea ice impacts their ability to hunt seals, leading to decreased food availability and reproductive success. International efforts are underway to monitor polar bear populations and address the threats they face.
