Grizzly bear

Description:

Most adult female grizzlies weigh 130–200 kilograms (290–440 lb), while adult males weigh on average 180–360 kilograms (400–790 lb). The average total length in this subspecies is 198 centimetres (6.50 ft), with an average shoulder height of 102 centimetres (3.35 ft) and hindfoot length of 28 centimetres (11 in). Although variable from blond to nearly black, grizzly bear fur is typically brown in color with white tips.[5] A pronounced hump appears on their shoulders. It shares the same environment with an elk or a squirrel, or a deer, Black bear. Basically anything that live in the mountains or by trees. They are at the top of the food chain, therefore the grizzly bear doesn't have very many symbiotic relationships. Grizzly bears may also have a very keen sense of smell to find food for their young cubs and themselves. Grizzly bears do not have very good eyesight so that is why the grizzlies have a good sense of smell. This is an adaptation because if the grizzlies can't see their food they can use their noses to sniff out things. Grizzly bears can stand on their back legs to let them see further away to the point where most animals can't see. This also helps them find scents with ease. This is an adaptation because the grizzlies can see if there is predators or if danger approaches.

Habitat:

generally lives in the uplands of western North America.In North America, grizzly bears previously ranged from Alaska to Mexico and as far east as the Hudson Bay area.[6] In North America, the species is now found only in Alaska, south through much of western Canada, and into portions of the northwestern United States including Idaho, Montana, Washington and Wyoming, extending as far south as Yellowstone and Grand Teton National Parks, but is most commonly found in Canada. Grizzly bears have one of the lowest reproductive rates of all terrestrial mammals in North America.[11] This is due to numerous ecological factors. Grizzly bears do not reach sexual maturity until they are at least five years old.[6][12] Once mated with a male in the summer, the female delays embryo implantation until hibernation, during which miscarriage can occur if the female does not receive the proper nutrients and caloric intake.
