Brown Bear

Ursus arctos

Also known as Grizzly Bear, Kodiak Bear, Eurasian Brown Bear

Brown bears dominate northern wildernesses across North America and Eurasia, using their signature muscular shoulder hump to dig for roots, small mammals, and den sites. These solitary giants display remarkable behavioral adaptability, foraging on berries and vegetation for months before congregating at coastal rivers to harvest spawning salmon. Mothers raise cubs for up to three years, teaching complex survival skills while aggressively defending them against rival bears.
