Bonobo

Bonobos (Pan paniscus) are closely related to chimpanzees. They are most known for using sex to solve conflicts instead of fighting, and they live south of the Congo river, as opposed to their chimpanzee cousins. They are known to use click sounds.

Famous bonobos
Kanzi- An ape on the Great Ape Trust in Iowa. Known for his use of lexigrams (symbols for pointing at), of which he knows hundreds. He have also made Oldowan tools like those made by primitive cavemen, and have used fire to barbecue marshmallows. He made the fire by using modern equipment (not Stone Age equipment, sadly), and he extinguished the fire with water afterwards.

Panbanisha- A now dead ape at the same trust as Kanzi. She also used lexigrams.

Conservation status
The bonobos are severely endangered by deforestation, poaching and the illegal pet trade. Bonobos raised as pets are notoriously difficult to reintroduce into the wild. Traumatized bonobos frequently refuse to eat and as a result starve to death.
