The grizzly bear, ursus arctos, is a large subspecies of brown bear inhabiting North America. Scientists generally do not use the name grizzly bear but call it the North American brown bear. Multiple morphological forms sometimes recognized as subspecies exist, including the mainland grizzly, Kodiak bear, peninsular grizzly, and the recently extinct California grizzly and Mexican grizzly bear. On average bears near the coast tend to be larger while inland grizzlies tend to be smaller.
