An adult bonobo, a black-faced chimpanzee, munches on vegetables with a baby bonobo at a shelter called "Lola ya Bonobo" (the paradise of Bonobos in Congo) in Kinshasa, capital of Congo, Aug 22, 2010. Bonobos mainly live in primary forests of Northern Congo. No more than 5,000 bonobos live in the wild due to years of civil war and illegal slaughter. The shelter is a protection center for the animals and now is home to more than 60 bonobos. [Photo/Xinhua]
