Javan Slow Loris, Indonesia (USNM 521836)

USNM 521836

Lorises are primates and are more closely related to humans, apes and monkeys than any other living nonhuman primate group. The Smithsonian Institution’s Division of Mammals ( houses many lorises in its scientific collections. 

This specimen, USNM 521836 (, is a male Javan slow loris (Nycticebus javanicus) from Indonesia. This individual was collected in 1971 near Tjilegong on the island of Java. This individual weighed 0.5 lbs, has a total length of 220 mm, a tail length of 16 mm, a hind tarsus length of 55 mm, and an ear notch length of 12 mm.

This is a CT scan of the cranium of USNM 521836. 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 nonhuman primate relatives available in 3D for education and research.
