We just learned about the Emperor Tamarin.
Another type of new world monkey is the Brown-Mantled Tamarin, also called Spix's saddle-back tamarin or leontocebus fuscicollis.
This is a small monkey that lives in South America, and grows to be less than 2 pounds.
They mostly live in the trees, and they have a dark brown head and shoulders.
