The Kamchatkan Brown Bear ( Ursus arctos ) is a species of bear that
can reach masses of 130700 kg (3001500 pounds ).
The Grizzly Bear ( Ursus arctos horribilis ), the Kodiak Bear and
the Mexican Brown Bear are North American subspecies
of the Brown Bear. It is sometimes referred to poetically as the bruin.
Brown Bears have furry coats in shades of blonde, brown, black,
or a combination of those colors;
the long outer guard hairs are often tipped with white or silver,
giving a "grizzled" appearance.
Brown bears have a large hump of muscle over their shoulders, giving
strength to the forelimbs for digging.
Their forearms end in massive paws tipped with extremely powerful
claws that can be up to 15 cm (5.9 inches ) in length.

Their heads are large and round with a concave facial profile.
In spite of their size, some have been clocked at speeds in excess
of 56 km/h (35 mph).
Along with their strength and deceptive speed, Brown Bears are legendary
for their physical stamina.
They are capable of running at full speed for miles at a time without
