Mico-leão-dourado - (Golden lion tamarin)

Leontopithecus rosalia


The Golden lion tamarin or mico-leão-dourado, as it is called in Brazil, on average, adults (male and female) weigh 17 to 24 ounces (481.9 to 680.4 grams) and measure 6 to 10 inches (15.2 to 25.4 cm) not including the tail, which measures about 12 to 15 inches (32 to 40 cm).
They eat fruits, flowers, nectar, plant exudates (gums) and animal prey (including frogs, snails, lizards, spiders and insects).


As an endemic species of Atlantic Forest that are extinction threatened, they rarely are viewed like this one, and I could not be more happy to found it, four weeks ago, completely free at the forest, mixed in a group of Black-tufted marmoset (sagui-de-tufo-preto), and away from the area where their populations are currently being controlled.


Golden lion tamarins have a number of features that are atypical for the Order Primates. Their thumbs are not fully opposable and their hallux (big toe) is located back from the other digits (similar to a bird’s big toe) and retained its flat nail. Unlike most New World primates, golden lion tamarin tails are not prehensile. After a week, this wonderful primate abandoned the group and was not more viewed together with them at the places where they are seen almost three times by day.
