The Polar Bear (Ursus martimus) is one of the largest land carnivores on the entire planet, with adult males weighing up to 1,700lbs (771kg). They are perfectly adapted for a cold weather environment, sporting think fur everywhere, including on their feet. The fur is white to camouflage them in the snow, but underneath their skin is black, which allows them to soak up heat more quickly. They are also excellent swimmers.
Though they are technically omnivores, Polar Bears feed mostly on other animals. Seals make up a large part of their diet, and are hunted by waiting on the ice near breathing holes where Seals surface for air. They do also feed on carrion, fish, birds, and some vegetation. Some bears will travel thousands of miles in a year while tracking food.
Polar Bears are listed as Vulnerable, and their numbers are threatened by habitat loss and climate change. Warming in the Arctic and loss of pack ice has limited their ability to hunt, placing the population on a decline.
