It depends on who you ask and what you mean by "largest", but the general concenus is that the polar bear is the "largest". It is a close call, but the polar bear is generally considered the largest bear on Earth. A close second is the brown bear, specifically the Kodiak bear. The Kodiak is a subspecies of the brown bear native to Alaska. The consensus among experts is that the polar bear is the largest, but some believe the Kodiak bear to be larger. Part of the dissension comes from the vagueness of the word "largest." The answer really depends on how "largest" is defined - Heaviest? Longest? Largest ever recorded? A comparison of the average measurements of the polar and brown bear: Average Weight of Mature Male: Polar-900-1,500 pound /Brown-500-900 pounds Average Length of Mature Male Polar 8-8.4 feet/Brown 7-10 feet However, the heaviest bear ever recorded was indeed a brown bear at 2,500+ lbs. The heaviest recorded polar bear came in at around 2,210 lbs. Another entry (wikipedia.com) states: "The Polar Bear (Thalarctos maritimus or Ursus maritimus) is a large mammal of the order Carnivora, family Ursidae. It is a circumpolar species found in and around the Arctic Ocean. It is the world's largest land carnivore."

Polar bear

the polar bear is the largest but the most agressive is the koala which has been known to severely attack the legs of people near their tree

Some sources say the Polar bear others say the Brown Bear A polar bear can weigh anything up to 1760lbs, that is as much if not more than a horse. I have looked up several different sources and all have given different species of bear both in the English and latin Britanica give the Kodiak Bear as the largest species. So after searching I am really little wiser . If i had been asked before this question i would have said the Polar Bear, now Iam totally unsure and confused
