There are 9 subspecies of binturong, the second largest species in the family Viverridae.
The binturong is the only animal in the family Viverridae with a prehensile tail. The tail has fluffy and rough hair, which can grasp and act as a fifth hand, and can be used to hang the body in mid-air by wrapping around branches. In fact, only two carnivorous animals have such a tail, and the binturong is one of them. Moreover, in the Eastern Hemisphere, the binturong is the only mammal with a grasping tail.
Binturongs are nocturnal animals, active more frequently at dawn and dusk, and sometimes in the morning. They have been found to move and forage with gray leaf monkeys and white-cheeked gibbons. The binturong's sharp claws and grasping and entangled tail allow it to climb tall trees freely. It can jump and climb between branches to find food, and use its tail to wrap around branches to help maintain balance. Their hind legs can bend backwards at a large angle so that they can climb down from the tree headfirst. They live in trees all year round and are typical arboreal animals.
Binturongs are plantigrade animals, and they walk with their soles on the ground, which is similar to bears; their eyes turn into vertical slits when exposed to strong light, which is very similar to cats. Binturongs are named after these two similarities. They use the olfactory glands located on their tails to rub on trees to mark their territory, communicate with their peers through smell, and leave a trail of smell marks when climbing trees. The smell of the substance secreted by the olfactory glands of binturongs is often described as "similar to hot popcorn." They become extremely ferocious when threatened, and make giggling sounds when they are happy
In the past, binturongs were not distributed in a large area in China. It is only distributed in some border counties in the southwest and south of Yunnan. The population in Xishuangbanna has been greatly reduced due to the greatly reduced habitat. There may still be dozens of binturongs in the Tongbiguan Nature Reserve (Nabangba) in Yingjiang, western Yunnan. The number of binturongs in China is estimated to be less than 200, and it is in a highly endangered state.
The felling and destruction of the native tropical forests in the habitat are the main factors causing the endangerment of binturong. Especially after the 1970s, most of the tropical and subtropical original forests in Guangxi and southern Yunnan were reclaimed and destroyed, which destroyed most of the habitats of binturongs, causing the disappearance or reduction of binturongs in those areas; in addition, China is the marginal area of binturong distribution, the small population, and the fragmentation of distribution area are also factors that endanger this species.
