Introduction During the early 1900s, two specimens of Pygmy Tarsier (Tarsius pumilus) were discovered. The Tarsius pumilus (T. pumilus) collected were morphologically different from the known species of tarsier found in the museum as they had a remarkably small body. In 2000, a living population of T. pumilus was found in the central Sulawesi, proving that the species still existed. The species is also distinct as the 3 specimens were found in much higher altitude compared to other Sulawesi tarsier
