This is one of about 13 species of tarsiers, the smallest living primates in the world. It is the size of a person's fist. I photographed it on the island of Sulawesi in Indonesia. These nocturnal animals are native to several islands in Southeast Asia including the Philippines. I had to use flash because it was so dark, and because the vegetation was dense I couldn't hold the flash off to the side for sidelighting -- which I would have preferred. I worked with a biological researcher in primates to locate one of these tiny animals because I could never have found one myself. Just three years ago two new species of tarsiers were discovered on Sulawesi. My settings were 1/200, f/8, and 400 ISO. I used a 100-400mm telephoto for the shot.
