The Kodiak Brown Bear (Ursus arctos middendorffi), also known as the Alaskan brown bear, is the largest subspecies of Brown Bear and occupies the islands of the Kodiak Archipelago in Southcentral Alaska. Brown bears on Kodiak Island are classified as a distinct subspecies from those on the mainland because they are genetically and physically isolated.
The shape of their skulls also differs slightly. The term “brown bear” is commonly used to refer to the members of this species found in coastal areas where salmon is the primary food source. Brown bears found inland and in northern habitats are often called “grizzlies.” Normally defined as being 75 miles from the sea.
