Bengal Slow Loris, Thailand (USNM 296915)

USNM 296915

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 296915 (, is a Bengal slow loris (Nycticebus bengalensis) from Thailand. This individual was collected in 1952 near Takhanon Hinlaem in Kanchanaburi Province. This individual had a total length of 350 mm, a tail length of 22 mm, a hind tarsus length of 75 mm, and an ear notch length of 24 mm.

This is a CT scan of the mandible of USNM 296915. 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.
