Gibbons, not monkeys, are the world's smallest apes.
Gibbons can cover distances of up to 15 metres in a single leap, thanks to their strong arms.
They form lifelong monogamous pair bonds, often staying together until death.
Gibbons communicate through loud, musical voices that can be heard over long distances in their forest habitats.
There are 20 recognised species of gibbons.
Besides fruit, gibbons also eat young shoots, leaves, seeds, skin, and flowers.
Groups of gibbons typically sleep together on the same tree for a certain period.
