There are only eight types of bears in this world including the polar bear and brown bear. Spectacled bear, sloth bear, giant panda, sun bear, Asiatic black bear and American black bear are other six members of this family.
Members of bear family are big, furry mammals with large heads, thick legs and short tails. They have five claws on each foot. Bears have a good sense of smell as they have a well developed large nose but have weak eyesight and hearing.
The polar bear is strictly carnivorous or meat-eating while the giant panda feeds entirely on bamboo plant. Other six bears eat a variety of food material.
Polar bears live in the Arctic. They are excellent swimmers. They have a thick coat of fur, which keeps them warm in chilly Arctic weather.
Bears usually live alone and are solitary animals. A mother bear protects its cubs during their first year of birth and teaches them survival techniques. Bears normally walk slowly but they can gallop at very high speed, if they feel the need to do so. Most bears are also able to climb trees. The sun bear can even make nests in trees!
Brown bears are the largest and most widely distributed bears in the world. A brown bear can stand up to 11 ft or 3.5 m tall – that's twice the size of a tall man!
Many bears become dormant or inactive in winters and sleep nonstop for a long time.
