Polar Bear vs Brown Bear

Polar bear and brown bear are two carnivorous mammals living in two different ecosystems. Both of them belong to the same genus and different species. They exhibit a range of differences including the coat colour, and this article aims to discuss their characteristics with emphasis on different features.

Polar Bear

Polar bear, Ursus maritimus, is an attractive carnivore and native to the Arctic Circle. They fall into the category of Vulnerable according to the IUCN red list, as their populations are declining at a rapid rate. It is the largest land living member of the Order: Carnivora, and a matured adult’s weight ranges from 350 to 680 kilograms, and the body length could go up to three metres. Polar bears exhibit many adaptations to live in snow. Their legs are stocky and have a long nose and small ears. In addition, polar bears have large feet, which are advantageous to walk on the snow and to swim in the sea. The paws have soft papillae to provide a better traction on the ice. Their claws are short and stocky which help them to catch heavy preys. Sometimes, they are referred as marine mammals, because polar bears spend much time of their lifetime in the sea. They have small and jagged jaws with sharp and strong canines. Unlike many carnivores, polar bears are not territorial animals. They have an excellent vision and a very good sense of smell, which are helpful for their carnivorous habits. However, their unique and beautiful snow-white coat has attracted much of the peoples’ love.
