Bears
are big, carnivorous (flesh-eating) mammals with shaggy fur. They are closely
related to dogs, but are much larger and have no tail. Big bears may grow up to
10 feet in length. They have thick, powerful legs and strong claws. In spite of
their size, bears
are nimble creatures, climbing quickly up trees and over
boulders. Except for the polar bear, they are mainly forest animals.
In many
stories, bears are shown as friendly animals, and they are popular for their
tricks – such as standing on their hind legs – in captivity. But they are
dangerous animals. In the wild, they may attack, kill, and eat a man without
warning. Their normal food consists of small animals of all kinds, fish, birds’
eggs, and even farm animals. But they also eat fruits, berries, roots, and
other plant foods. They are very fond of honey.
Most
bears live in the northern hemisphere. The black bear of North America is among
the most numerous. It reaches a weight of about 300lb, and, in spite of its
name, may be brown. The Asian black bear is a quite different species that
lives in the Himalayas, China, and Japan. It has a white V-shaped marking on
the chest.
The
brown bear of Europe and northern Asia – and the almost identical grizzly bear
of North America – is much bigger than the black bear, weighing up to 1500 lb.
in spite of this size; brown bears are extremely quick and swim well. They are
very powerful and are probably the most dangerous of all bears.
Polar
bears are perhaps the best known bears. They live on Arctic ice flows, where
their yellowish-white fur gives them good camouflage. Their main food is seal
meat, but they also eat some fish, birds, and birds’ eggs. They roam
constantly, looking for food, but the female may spend the winter in a den
under the snow where the young are born. Fully grown polar bears weigh up to
about 1600lb.
Other
bears include the spectacled bear of South America, the sun bear of Asia, and
the long-nosed sloth bear of India.
