Bonobo baby posted via sos-animaux-sans-defense.e-monsite.com. Bonobos are members of the great ape family, along with gorillas, orangutans, and chimpanzees. Earlier scientists thought the bonobo Pan paniscus was just a smaller version of the common chimpanzee Pan troglodytes and so the term “pygmy chimpanzee” was used. But don’t be fooled! Bonobos and chimps are really quite different.
