I was shocked at first that there are other Tarsiers in other country aside from Philippines. The Pygmy Tarsier is one of the smallest mammal in the world. It can turn its head 180 degrees. Tarsius pumilus, also known as the Mountain Tarsier or the Lesser Spectral Tarsier, is a nocturnal primate found on central Sulawesi, Indonesia, in an area with lower vegetative species diversity than the lowland tropical forests.
