Siamangs are apes and one of our closest living relatives. The Smithsonian Institution’s Division of Mammals (http://vertebrates.si.edu/mammals/) houses many siamangs in its scientific collections.
This specimen, USNM 143577 (http://collections.mnh.si.edu/search/mammals/?irn=7251562), is a young male siamang (Symphalangus syndactylus) from Indonesia. This individual was collected by William Abbott near Aru Bay on the island of Sumatra. This individual weighed 23.25 lbs and had a hind tarsus length of 158 mm. The male had a head to body length of 585 mm.
This is a CT scan of the cranium of USNM 143577. 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 (http://smithsonian20.si.edu/fund.html), 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.
