Today we spotted a Missouri Beaver swimming using its webbed hind feet. The beaver is a very large bulky rodent with a rounded head and rounded ears. Also has a flat tail and dark brown fur. The missouri beaver is about 3 to 4 feet in hight and weighs between 44 to 60 pounds. When we first saw the beaver swimming as fast as it was we thought that it was a fish then we discovered it was the missouri beaver.
