  • The face of an ape is as individual as a human’s.
  • Apes can live into at least their forties or fifties in the wild.
  • An adult male gorilla can weigh about 170 kilos compared to 60-80 kilos for females.
  • Adult male gorillas can eat 30 kilos of vegetation per day!
  • Chimpanzees do not beat their chests but gorillas do.
  • Chimpanzees use tools to feed, modifying twigs and grass stems to fish for termites and ants, using stone hammer and anvils to crack nuts and leaf sponges to drink water.
  • Females become more adept at termite fishing at an earlier age than males!
  • The eastern chimpanzee does not crack nuts with a hammer and anvil, while chimpanzees in Senegal fashion spears to hunt. Variation in tool use and behaviour between different populations has led scientists to attribute culture to this species.
  • Chimpanzees produce an acoustic drumming display by pounding the buttresses of trees with their hands and feet. It’s thought that individuals may communicate their location as they travel in this way.
  • Chimpanzees and gorillas build nests to sleep in. Most chimpanzee nests are built in trees. Gorillas and some populations of chimpanzee also build nests on the ground.
  • Apes are closely related to humans and are highly susceptible to many human infectious diseases including pneumonia, influenza, polio, TB, malaria, scabies and Ebola. Chimpanzees self-medicate.
