While most primates face the threat of extinction, in Brazil, Golden Lion Tamarins are bucking the trend.

To save this species from extinction, the Brazilian conservationists says there must be at least 2,000 tamarins living in protected areas by 2025. Golden lion tamarin monkeys are among the world's rarest mammals, with only about 1,400 living in the wild.
