Spectral Tarsier, Tangkoko National Park, Sulawesi, IndonesiaJust a simple portrait of a spectral tarsier going out to a friend who can use a simple portrait of a spectral tarsier right about now. This image gives a good look at the spurs, or toilet claws, on the feet. They are used for grooming and digging for insects. Tarsiers are one of the smallest primates in the world and they have the largest eyes to body ratio of any mammal. Their eyes are even larger than their brains. Nikon D300 with Nikkor 200-400mm lens (at 220mm) ISO 200, f/10 at 1/60th of a second, two Nikon SB-800 flash units.
