Brown bears (Ursus arctos) are one type of bear. Live in the eastern regions of Eurasia and North America. Brown bears can weigh 130-700 kg (300-1500 pounds). Kodiac bears are among the largest types of brown bears, which are about the size of a polar bear that has the most members in the family of bears which are the largest land predators. There are several subspecies of brown bears, including Syrian brown bears, Kodiak brown bears, Alaska brown bears, American brown bears (grizzly) and Mexican brown bears.
Brown bear populations exist in parts of Russia, the United States (mostly Alaska), Canada, the Carpathian region (mainly Romania), also in Ukraine, Slovakia, Poland and so on). Even the Balkans, Sweden, and Finland designate bears as national animals. So, Brown Bear has the most extensive habitat of all bears.
There is little agreement about the classification of brown bears. Brown bear species have been proposed as many as 90 species, but recent DNA analysis has only grouped into five groups of organisms and their offspring (Klade). In 2005, at least 16 subspecies were recognized, including:
Eurasian brown bear
Europe, Caucasus, Siberia (except east) and Mongolia
Kamchatka Brown Bear
This bear is very large, dark brown. Light-colored ones found in Europe-Siberia. The paws are dark;
Ursus arctos californicus
This bear that was last known to be alive was shot in California in 1922.
East Siberian brown bear
Eastern Siberia, from the Yenisei River to the Altai Mountains, is also found in eastern Mongolia. Some are dark-colored, of medium size with a larger proportion of the skull
Temporary habitats still exist in the Atlas Mountains and surrounding areas, in North Africa, from Morocco to Libya. This bear, the last known to survive, was killed by poachers estimated in the 1870s.
