Grizzlies vary greatly in color from cream through cinnamon to brown to black. They also have a distinguishing shoulder hump of flesh and muscle. It is not stored fat. The name ""grizzly"" comes from the silver-tipped guard hairs that appear around the bear's face in autumn, giving it a grizzled appearance.
