The female, named Belle, is 20 months old and is one of four bonobos that arrived at the San Diego Zoo last month, from the Cincinnati Zoo. Bonobos live together in integrated family groups. Belle, her mother, older brother and sister integrated easily into the existing bonobo troop providing them the opportunity for the kind of social interaction they would have in the wild. Bonobos are a very rare and critically endangered great ape species native only to the Democratic Republic of Congo, but the wild populations are being decimated at an alarming rate. They are very closely related to humans, sharing 98.4 percent of the same DNA. The San Diego Zoo is one of only a handful of zoological institutions in the United States that house and care for this rare species.
