The polar bear is the largest living species of bear and land carnivore, though some brown bear subspecies like the Kodiak bear can rival it in size. [ 31 ] [ 32 ] Males are generally 200–250 cm (6.6–8.2 ft) long with a weight of 300–800 kg (660–1,760 lb).
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 brown bear (Ursus arctos) is a large bear native to Eurasia and North America. Of the land carnivorans, it is rivaled in size only by its closest relative, the polar bear, which is much less variable in size and slightly bigger on average. The brown bear is a sexually dimorphic species, as adult males are larger and more compactly built ...
By far the largest bear species discovered, estimated to stand around 4.0 m (13 ft) and weighing 1,600 kg (3,500 lb), they are genetically closer to the spectacled bear (Tremarctos ornatus), than to Arctodus of North America, implying the two extinct forms evolved large size in a convergent manner.
Polar bear (left) and sun bear, the largest and smallest species respectively, on average The bear family includes the most massive extant terrestrial members of the order Carnivora. [ a ] The polar bear is considered to be the largest extant species, [ 42 ] with adult males weighing 350–700 kg (770–1,540 lb) and measuring 2.4–3 m (7 ft ...

Tremarctinae appear to have a disproportionately shorter snouts compared with most modern bears, giving them the name "short-faced." This apparent shortness is an illusion caused by the deep snouts and short nasal bones of tremarctine bears compared with ursine bears; Tremarctinae had a deeper but not a shorter face than most living bears.
