Potto, Nigeria (USNM 377274)

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 377274 (, is a female Calabar potto (Arctocebus calabarensis) from Nigeria. This individual was collected in 1966 by H. J. Herbert near Calabar. This individual weighed 346 g, had a total length of 270 mm, a tail length of 12 mm, a hind tarsus length of 40 mm, and an ear notch length of 25 mm.

This is a CT scan of the mandible of USNM 377274. 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.
