The largest individual bear from an existing species was a male polar bear that weighed about 2,210 pounds. Polar bear is the largest land carnivore as well as the largest bear in the world. The average weight of male Polar bear is around 900 pounds to 1500 pounds and average length of almost 8 to 9 feet. It is from the icy waste of the Arctic. The size of male bear (Boar) is about 350-680 kg while the female (Sow) is about half of the size of male. The global population of polar bears is a bit difficult to estimate, but according to a research it is recorded that there are almost 20,000-25,000 bears are found in the whole world.

Polar bear is the largest bear in the world. They are also considered as the largest carnivores living on land. Polar bears are found around the Arctic Circle along the edges of Arctic Ocean and are found on icy land. They are born on land but spend most of their time in water. For this reason, they are also called marine mammals with their scientific name being maritime bear. The natural habitat of the largest bear in the world includes open waters, snow and ice. They hunt on seals and fish found around the sea for their food.

Polar bears are considered as vulnerable to extinction because of the increasing rate of polar bear hunt in the last decade. This has caused a drastic decrease in the quantity of these bears in the last few years. Because of this, there is a fear regarding the future of these species. Their behavior is very much different than other bears. Apart from their basic nature, they prefer escaping rather than fighting. Normally they do not attack humans. But a hungry polar bear is sometimes very unpredictable. They can kill and eat humans as well.
