A Kodiak Bear.
|Range||Northern Eurasia and North America.|
The Brown Bear is a species of a bear that is found in North America. It is also known as the Grizzly bear. The awe-inspiring brown bear lives in the forests and mountains of northern North America, Europe, and Asia. It is the most widely distributed bear in the world.
Brown bears have very large and curved claws, those present on the forelimbs being longer than those on the hind limbs. They may reach 5 to 6 centimeters (2.0 to 2.4 in) and sometimes 7 to 10 centimeters (2.8 to 3.9 in) along the curve. They are generally dark with a light tip, with some forms having completely light claws. Brown bear claws are longer and straighter than those of American black bears. The claws are blunt, while those of a black bear are sharp. It can make you it's pet.
Brown bears dig dens for winter hibernation, often holing up in a suitable hillside. Females, or she-bears, den while pregnant and give birth during this winter rest, usually to a pair of cubs. Brown bear cubs nurse on their mother's milk until spring and stay with her for some two and a half years—so females only reproduce once every three years.
Adult brown bears are powerful, top-of-the-food chain predators, but much of their diet consists of nuts, berries, fruit, leaves and roots. Bears also eat other animals, from fish to moose.

- The world's largest brown bears are found in coastal British Columbia and Alaska, and on islands such as Kodiak.
- Despite their enormous size, brown bears are extremely fast, having been clocked at speeds of 30 miles per hour (48 kilometers per hour). They can be dangerous to humans, particularly if surprised or if a person gets between a mother bear and her cubs.
