Arctodus is an extinct genus of short-faced bear that inhabited North America during the Pleistocene (~2.5 Mya until 12,800 years ago). There are two recognized species: the lesser short-faced bear (Arctodus pristinus) and the giant short-faced bear (Arctodus simus).
The last short-faced bear, and the ecological successor of A. wingei, is the spectacled bear. Arctotherium was named by Hermann Burmeister in 1879. Tremarctinae (and therefore Arctotherium ) appeared to have disproportionately shorter snouts compared to most modern bears, hence the name "short-faced" was given to them.
The Tremarctinae or short-faced bears is a subfamily of Ursidae that contains one living representative, the spectacled bear (Tremarctos ornatus) of South America, and several extinct species from four genera: the Florida spectacled bear (Tremarctos floridanus), the North American giant short-faced bears Arctodus (A. pristinus and A. simus), the South American giant short-faced bear ...
The polar bear (Ursus maritimus) is a large bear native to the Arctic and nearby areas. It is closely related to the brown bear, and the two species can interbreed.The polar bear is the largest extant species of bear and land carnivore, with adult males weighing 300–800 kg (660–1,760 lb).

Bear habitats are generally forests, though some species can be found in grassland and savana regions, and the polar bear lives in arctic and aquatic habitats. Most bears are 1.2–2 m (4–7 ft) long, plus a 3–20 cm (1–8 in) tail, though the polar bear is 2.2–2.44 m (7–8 ft) long, and some subspecies of brown bear can be up to 2.8 m (9 ...
[6] [7] Along with other large bears such as the cave bear, short-faced bears Arctodus and Arctotherium, and an extinct subspecies of the modern polar bear Ursus maritimus tyrannus, Agriotherium was among the largest known terrestrial members of Carnivora. They had longer legs and shorter faces than other bears, and were more lightly built.
The spectacled bear (Tremarctos ornatus), also known as the South American bear, Andean bear, Andean short-faced bear or mountain bear and locally as jukumari (Aymara and Quechua [3]), ukumari or ukuku, is a species of bear native to the Andes Mountains in northern and western South America.
