Golden lion tamarins (GLTs) are an endangered species native to Brazil's Atlantic coastal forest. In the early 1970s, there were fewer than 200 of these small monkeys. Thanks to the National Zoo, other zoos, conservation organizations, and Brazil's government, there are now about 1,500 living in the wild.
