Brown bear
phylum | Chordata | The brown bear (Ursus arctos) is a large bear with the widest distribution of any living ursid. The species is distributed across much of northern Eurasia and North America. It is one of the two largest terrestrial carnivorans alive today, rivaled in body size only by its close cousin, the polar bear (Ursus maritimus). There are several recognized subspecies, many of which are quite well-known within their native ranges, found in the brown bear species.

Grizzly bear
phylum | Chordata | The grizzly bear (Ursus arctos ssp.), is any North American subspecies of the brown bear, such as the mainland grizzly (U. a. horribilis), the Kodiak (U. a. middendorffi), the peninsular grizzly (U. a. gyas) and the recently extinct California grizzly (U. a. californicus). Specialists sometimes call the grizzly the North American brown bear because the grizzly and the brown bear are one species on two continents.

† Atlas bear
phylum | Chordata | The Atlas bear was Africa's only native bear that survived into modern times. Once inhabiting the Atlas Mountains and neighbouring areas, from Morocco to Libya, the animal is now thought to be extinct. The Atlas bear was brownish black in colour, and lacked a white mark on the muzzle. The fur on the underparts was reddish orange.
