The Brown Bear is the largest terrestrial carnivoran. The largest subspecies, the Kodiak bear (Ursus arctos middendorffi), rivals the polar bear as the largest member of the bear family. Other subspecies include the Grizzly bear (Ursus arctos horribilis), Alaska brown bear (Ursus arctos alascensis), Dall Island brown bear (Ursus arctos dalli), Peninsular brown bear (Ursus arctos gyas), Ursus arctos sitkensis and Stikine brown bear (Ursus arctos stikeenensis).
The size range for Kodiak bear females (sows) is from 225 to 315 kg (496 to 694 lb) and for males (boars) is 360 to 635 kg (794 to 1,400 lb). Mature males average 480–533 kg (1,058–1,175 lb) over the course of the year, and can weigh up to 680 kg (1,500 lb) at peak times. Females are typically about 20% smaller and 30% lighter than males.
