Gibbons are the acrobats of the primate world. These lesser apes live in small family troops in the rainforest treetops of south east Asia, defending their territories with visual displays and musical duets. They are masters of movement in the trees, swinging through the branches using their remarkably long forearms, and covering over nine metres in a single leap. Unfortunately, most species in this family are under threat from deforestation.
Scientific name: Hylobatidae
