FACTS. 1  Life span: About 20 to 30 years. 2  How big is a grizzly bear? Size is up to 4 feet when on all four paws. 3  Weight: 350 to 800 pounds for male bears, and roughly 25% less for females. Weight depends on what they eat, where they live, and season.
The best indicators are the size of the shoulders, the profile of the face and the length of the claws. The grizzly bear has a pronounced shoulder hump, which the black bear lacks. It also has a concave or âdishedâ facial profile, smaller ears and much larger claws than the black bear. Black bears have a flatter, âRoman-noseâ profile, larger ears, no visible shoulder hump and smaller claws.
