Gibbon, Indonesia (USNM 144091)

USNM 144091

Gibbons are apes and one of our closest living relatives. The Smithsonian Institution’s Division of Mammals ( houses many gibbons in its scientific collections.

This specimen, USNM 144091 (, is a male agile gibbon (Hylobates agilis) from Indonesia. This individual was collected by William Abbott near the Little Siak River on the island of Sumatra.  This male weighed 12.5 lbs and had a head to body length of 450 mm.

This is a CT scan of the cranium of USNM 144091. These three-dimensional scans are made publicly available through the generous support of the Smithsonian 2.0 Fund, provided from the annual gifts of the Smithsonian National Board to the Secretary to use at his discretion (, and the Smithsonian Collections Care and Preservation Fund.

The main goal of this joint initiative between the Human Origins Program and the Division of Mammals is to make the NMNH's scientific collections of our closest living relatives, the apes, available in 3D for education and research.
