While there has been much confusion about the taxonomy of brown bears (Ursus arctos), taxonomists agree there are at least two subspecies in North America -- the grizzly bear (U. a. horribilis) and the Kodiak bear (U. a. middendorffi).

Grizzly bears are very strong and large animals. Their size and weight are variable depending on the availability of food, and the climatic conditions. The adult bears stand approximately 100 cm tall on all four legs. Their body length is just over 200 cm, and their weight is variable, normally anywhere from 330 to 825 pounds.
