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:
Sun bear
The sun bear's fur is usually jet-black, short, and sleek with some under-wool; some individual sun bears are reddish or gray. Two whirls occur on the shoulders, from where the hair radiates in all directions. A crest is seen on the sides of the neck and a whorl occurs in the centre of the breast patch. Always, a more or less crescent-shaped pale patch is found on the breast that varies individually in colour ranging from buff, cream, or dirty white to ochreous. The skin is naked on the upper lip. The tongue is long and protrusible. The ears are small and round, broad at the base, and capable of very little movement. The front legs are somewhat bowed with the paws turned inwards, and the claws are cream.
