Adult female grizzly bears can weigh from 200 to 450 pounds, while the adult male of the species weighs anywhere from 300 to 850 pounds. The largest documented grizzly on record weighed 1,200 pounds and stood 10 feet tall.
Most grizzlies are much shorter, however, standing 6 to 7 feet tall on their hind legs or 3 to 3.5 feet tall at the shoulders when they're on all fours. Despite their large size, grizzlies can move at top speeds of up to 35 miles per hour when the occasion calls for it. The grizzly bear can be found in Wyoming, Idaho, Montana and Washington, as well as parts of Alaska and Canada.
Grizzlies are omnivores that eat a variety of plants, insects and animals. Although their diet varies by their location, they normally eat berries, seeds, grasses, roots, elk, deer and fish. During the late summer months into the early fall, bears will pack on weight for the upcoming winter, sometimes gaining up to three pounds or more per day. Notably, a grizzly bear has an acute sense of smell that is more finely attuned than that of a blood hound. This heightened sense of smell allows the grizzly to detect sources of food from miles off.
