Golden-headed lion tamarins only live in the southern part of Bahia in Brazil. They live up 10-33 ft. in the tropical and semi-deciduous forest biomes.
The animal fluffs up its fur to make it look bigger, and the tamarin has very long fingers. Four have long nails, but the 5th has a flattened nail like all primates. Primates is a fancy name for monkeys.
