Asian black bear
Along with sun bears, Asiatic black bears are the most typically used species in areas where bears are either used in performances or as pets. Asian black bears have an outstanding learning ability in captivity, and are among the most common species used in circus acts. According to Gary Brown:
Alaska Peninsula brown bear
There is debate as to if Alaska Peninsula brown bears should be referred to as "grizzlies" along with all other North American subspecies of the brown bear. There is confusion experienced when referring to inland and coastal ones separately, but biologists still maintain that coastal ones are truly brown bears. However, it is considered correct to place all North American members of "U. arctos" in the subspecies "horribilis" except the giant Kodiak bears of Kodiak Island. To avoid confusion, many simply refer to all North American members, including Kodiaks, as "grizzly bears."
