About the Black-pencilled Marmoset
The black-tufted marmoset (Callithrix penicillata) is a species of New World monkey that lives primarily in the Neotropical gallery forests of the Brazilian Central Plateau. It ranges from Bahia to Paraná, and as far inland as Goiás, between 14°S and 25°S, and can commonly be seen in the Rio de Janeiro city where it was introduced. This marmoset typically resides in rainforests, living an arboreal life high in the trees, below the canopy. They are only rarely spotted near the ground.
The black-tufted marmoset is characterized by black tufts of hair around their ears. It typically has some sparse white hairs on its face. It usually has a brown or black head and its limbs and upper body are gray, as well as its abdomen, while its rump and underside are usually black. Its tail is ringed with black and white and is not prehensile, instead used for balance. It does not have an opposable thumb and its nails tend to have a claw-like appearance. The black-tufted marmoset reaches a size of 19.0 to 22.1 centimetres (7.48–8.7 in) and weighs up to 350 g (12.35 oz).
The black-tufted marmoset has a lifestyle very similar to other marmosets, being diurnal... Wikipedia →
