Compared to the great apes, gibbons are relatively unknown and less understood. They are the smallest and fastest of all the apes They are extremely intelligent, and like great apes, gibbons form strong family bonds. There are twenty different species of small apes, two of which have only recently been discovered (see below).
The IUCN Group that focuses on Small Apes is the Section on Small Apes (SSA) of the IUCN SSC Primate Specialist Group. The SSA is a community of over ninety of the world's experts in gibbon conservation from twenty-one countries.
