This is a great site for information. Pictures are buried a bit, but it’s interesting to enter California in the keyword search. There are 62 species listed for the state of California!  For all of my students who hope to learn more, just browse around this site.

Endemic to Siau Island, Indonesia, the Siau Island Tarsier (Tarsius tumpara) was assessed as Critically Endangered. It is restricted to a very small area and there has been a suspected population decline of more than 80% in the past. It is locally collected as food. Furthermore, an active volcano, Mt. Karengentang, dominates more than half of its geographic range. The Siau Island Tarsier is considered to be one of the 25 most threatened primates by the IUCN Species Survival Commission Primate Specialist Group. Photo © Geoff Deehan
