Adult golden lion tamarins weigh only 20 to 24 ounces—that is less than 1.5 pounds! Since 1984, zoo-born golden lion tamarins have been reintroduced to the forests of Brazil. To date, about 40 percent of their wild population is due to the efforts of captive breeding and re-introduction.

Only 1,500 golden lion tamarins remain in the wild, living in the heavily populated coastal region of Brazil, where less than 2 percent of the original forest remains.
