The scientific name for the brown bear is Ursus arctos.
Smaller populations live in Wyoming, Montana, Idaho, and Washington.
They supplement their diets with the meat of animals such as fish and small mammals, when it's available. When a grizzly bear stands on its hind legs, it is not doing so as a threat. It's curious, trying to get a better view of its surroundings. People used to think that hippos sweat blood. The common hippo's close relative is the pygmy hippopotamus.
