The endangered, fist-sized Philippine Tarsier is one of the smallest primates in the world. Nocturnal, shy and tiny, with enormous eyes that give them excellent night vision, they are adorable-looking and endemic to certain areas of the Philippines. Conservation efforts are under way to protect them and their natural habitat of rainforests. A tarsier sanctuary in Bohol has a visitor center for those who wish to know more about this extraordinary mammal.
