The golden lion tamarin is the largest of the four existing tamarin species in the Leonidas genus, and the only one with red-gold fur all over its body.
The golden-headed lion tamarin has dark fur overall, with a reddish-gold tail, mane, and limbs. This tamarin lives only in the Brazilian state of Bahia.
The black lion tamarin calls Sao Paulo, Brazil, its home. It is black with a golden-colored rump. Researchers estimate that only 1,000 or fewer black lion tamarins remain in the wild.
The Superagui lion tamarin has orange fur with a black head, legs and tail. Its habitat includes Superagui Island and other area islands in the Brazilian state of Parana. This arboreal primate is even rarer than the black lion tamarin. Estimates count their populations as less than 400.
