Javan Slow Loris, Indonesia (USNM 521835)

USNM 521835

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 521835 (, is a male Javan slow loris (Nycticebus javanicus) from Indonesia. This individual was collected in 1971 near Tjibodas on the island of Java. This individual weighed 1.5 lbs, has a total length of 322 mm, a tail length of 25 mm, a hind tarsus length of 65 mm, and an ear notch length of 25 mm.

This is a CT scan of the mandible of USNM 521835. 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.
