Black bears reach a length between 5 and 6 feet. Black bears have a large degree of variability in weight, ranging from 200 pounds up to about 600 pounds.
Some bear species that are larger than the black bear include the polar bear and brown bear. Polar bears are generally about 8 feet long, and brown bears can reach a length of 10 feet. The black bear is the most prevalent bear species found in North America. A group of black bears is known as a sleuth or sloth, but these mammals are often seen alone. Male black bears may travel a territory of up to 80 square miles.
