Bonobos are quite possibly the most intelligent primates on Earth (other than us, of course!). The San Diego Zoo was one of the first zoos to include these highly endangered primates. One characteristic bonobos are especially known for is their ability to get along: unlike humans or chimpanzees, they have never been observed killing one of their own kind. Their habitat is dominated by giant rock outcroppings, and ropes and hammocks attached to bamboo sway poles, on which the bonobos nimbly climb or rest. Waterfalls and streams add to the African rainforest atmosphere here, but it is the bonobos themselves that will grab your attention. Do they remind you of anyone?
