We were born on July 17th at the Smithsonian's National Zoo.
We're usually born in sets of twins.
All members of our family take care of us (we're on dad's back here).
More than 178 of us have been born at the National Zoo - the last before us in May 2007.
We are endangered, and only 1,500 of us are left in the Atlantic coastal forest of Brazil.
In the wild, we eat fruits, insects and lizards. And hawks, cats and large snakes tend to eat us!
The National Zoo is working to reintroduce some of us into the wild.
Do you know what species we are?
