Polar bears can walk easily across icy surfaces. Nubs on their paw pads may help them get a grip.

Polar bears hunt seals by waiting for them to come to the surface of sea ice to breathe. When the seal nears the surface, the polar bear will bite or grab the seal and pull it onto land to feed. They also eat walruses and whale carcasses.

Polar bears move by walking and galloping and do not trot. Walking bears tilt their front paws towards each other. They can run at estimated speeds of up to 40 km/h (25 mph) but typically move at around 5.5 km/h (3.4 mph).

Heat Tolerance: Desert environments are characterized by high temperatures, so a polar bear would need to develop mechanisms to tolerate and regulate its body temperature. This could involve changes in its fur, such as a lighter color or thinner coat, to reflect sunlight and reduce heat absorption.
