The size of polar bears can vary depending on their geographic location. Polar bears that live in areas with abundant food sources, such as the coast of the Beaufort Sea, tend to be larger in size compared to those living in regions with limited food sources, such as the Hudson Bay.
For example, polar bears living in the Svalbard archipelago, located in the Arctic Ocean between Norway and the North Pole, are smaller in size compared to polar bears living in the Chukotka Peninsula in the Russian Far East. This variation in size can be attributed to the difference in food availability and environmental conditions in different regions.
Additionally, the size of polar bears can also vary depending on the time of year, with bears being at their largest just prior to entering their dens for the winter. This is due to the fact that they feed heavily on seals and other prey to build up their fat reserves for the winter months when food is scarce.
