Golden Potto, Equatorial Guinea (USNM 395710)

Lorises are primates and are more closely related to humans, apes, Old World monkeys and New World 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 395710 (, is a male golden potto (Arctocebus aureus) from Equatorial Guinea. This individual was collected in 1968 by C. J. Jones near Egnonangong in Rio Muni Province. This individual weighed 122.8 g, had a total length of 235 mm, a tail length of 24 mm, a hind tarsus length of 38 mm, and an ear notch length of 26 mm.

This is a CT scan of the cranium of USNM 395710. 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.
