Much like the grizzly bear and Eurasian brown bear, populations of the Ussuri brown bear (U. a. lasiotus) and the East Siberian brown bear (U. a. collaris) may vary widely in size. [3] [6] In some cases, the big adult males of these populations may have matched the Kodiak bear in size. [3]
The East Siberian brown bear (Ursus arctos collaris) is a population or subspecies of brown bear which ranges from eastern Siberia, beginning at the Yenisei river, north to the Arctic Circle, as far as Trans-Baikaliya, the Stanovoy Range, the Lena River, Kolyma and generally throughout Yakutia and the Altai Mountains.
The Ussuri brown bear (Ursus arctos lasiotus), also known as the Ezo brown bear, Russian grizzly bear, or the black grizzly bear, [3] is a subspecies of the brown bear or a population of the Eurasian brown bear (U. a. arctos). [which?] One of the largest brown bears, a very large Ussuri brown bear may approach the Kodiak bear in size. [4]
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 ...

The cave bear had a very broad, domed skull with a steep forehead; its stout body had long thighs, massive shins and in-turning feet, making it similar in skeletal structure to the brown bear. [17] Cave bears were comparable in size to, or larger than, the largest modern-day bears, measuring up to 2 m (6.6 ft) in length. [18]
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 ft). Weights range greatly from the sun bear , which can be as low as 35 kg (77 lb), to the polar bear, which can be as high as 726 kg (1,600 lb).
Captive bear with cub at Tierpark Hagenbeck, Germany. The Kamchatka brown bear is the biggest brown bear in Eurasia, [3] with a body length of 2.4 m (7.9 ft) to 3 m (9.8 ft) tall on hind legs, and a weight up to at least 650 kg (1,430 lb).
