Black-striped capuchin

The black-striped capuchin (Sapajus libidinosus), also known as the bearded capuchin, is a New World monkey in the family Cebidae, native to northern and central Brazil. It mostly lives in dry forests and savannah landscapes between the Rio Araguaia and the Rio Grande, in the Cerrados, Caatingas and Pantanal of Brazil. It is known for tool use, from cracking nuts with rocks to digging with sticks. Until recently it was treated as a subspecies of the tufted capuchin. It lives in highly social groups of 6 to 20 individuals. In its natural environment it is diurnal and spends much of its day travelling in search of food. Females reach sexual maturity around 5 years of age and give birth about every 24 months to a single infant.
