<Li> marikina Lesson, 1840 </Li> <P> The golden lion tamarin (Leontopithecus rosalia, Portuguese: mico - leão - dourado (ˈmiku leˈɐ̃w̃ dowˈɾadu), (liˈɐ̃w̃ doˈɾadu)), also known as the golden marmoset, is a small New World monkey of the family Callitrichidae . Native to the Atlantic coastal forests of Brazil, the golden lion tamarin is an endangered species . The range for wild individuals is spread across four places along southeastern Brazil, and a captive population is maintained at about 490 individuals among 150 zoos . </P> <P> The golden lion tamarin gets its name from its bright reddish orange pelage and the extra long hairs around the face and ears which give it a distinctive mane . Its face is dark and hairless . It is believed that the tamarin gets its hair color from sunlight and carotenoids in its food . The golden lion tamarin is the largest of the callitrichines . It is typically around 261 mm (10.3 in) and weighs around 620 g (1.37 lb). There is almost no size difference between males and females . As with all New World monkeys, the golden lion tamarin has tegulae, which are claw - like nails, instead of ungulae or flat nails found in all other primates, including humans . Tegulae enable tamarins to cling to the sides of tree trunks . It may also move quadrupedally along the small branches, whether through walking, running, leaping or bounding . This gives it a locomotion more similar to squirrels than primates . </P> <P> The golden lion tamarin has a very limited distribution range, as over time they have lost all but 2%--5% of their original habitat in Brazil . Today, this tamarin is confined to three small areas of the tropical rain forest in southeastern Brazil: Poço das Antas Biological Reserve, Fazenda União Biological Reserve, private land through the Reintroduction Program . The first population estimate made in 1972 approximated the count at between 400 and 500 . By 1981 the population was reduced to less than 200 . Surveys from as recently as 1995 suggested that there may only have been at most 400 golden lion tamarins left in the wild; they have made a nice comeback and now number 3200 in the wild . Tamarins live along the far southeast border of the country in the municipalities of Silva Jardim, Cabo Frio, Saquarema, and Araruama . However, they have been successfully reintroduced to the municipalities of Rio das Ostras, Rio Bonito, and Casimiro de Abreu . Tamarins live in coastal lowland forests less than 300 m (984 ft) above sea level . They can be found in hilltop forests and swamp forests . </P>
