<P> Physiologically , the Kodiak bear is very similar to the other brown bear subspecies , such as the mainland grizzly bear ( Ursus arctos horribilis ) and the now - extinct California grizzly bear ( U. a . californicus † ) , with the main difference being in size . While there is generally much variation in size between brown bears in different areas , most usually weigh between 115 and 360 kg ( 254 and 794 lb ) . The Kodiak bear , on the other hand , commonly reaches sizes of 300 to 600 kg ( 660 to 1,320 lb ) , and has even been known to exceed weights of 680 kg ( 1,500 lb ) . Despite this large variation in size , the diet and lifestyle of the Kodiak bear does not differ greatly from that of other brown bears . </P>
