•    chimpanzees are endangered with fewer than 300,000 estimated to be living in the wild. 


•    bonobos live only in the rainforest of Africa’s Congo Basin. 

•    they are the only great ape species in which females are the dominant sex.

•    bonobos live in large groups and are incredibly sociable and sexually active apes.

•    sexual behaviour plays a major role in group living, such as reducing aggressive behaviour.

•    bonobos are endangered with fewer than 60,000 estimated to be living in the wild.


•    gorillas live in Africa’s rainforest and mountainous areas.

 •    there are two species of gorilla: the Western and Eastern.
