Black-Tailed Marmoset, Pantanal, Brazil

Marmosets are very small monkeys. Most of the 22 different species are only about eight inches long (not including the tail). They are also fairly primitive with a less developed brain than other monkeys and several interesting physical characteristics like claws rather than nails. This black-tailed marmoset was photographed in the Pantanal of Brazil. Nikon D300 with Nikkor 200-400mm lens (at 400mm) ISO 1600, f/4 at 1/1000th of a second.
