The black-striped capuchin (Sapajus libidinosus), also known as the bearded capuchin, is a New World monkey in the family Cebidae. They can be found in northern and central Brazil. These capuchins mostly live in dry forests, and savannah landscapes between the Rio Araguaia and the Rio Grande.[3] Known for its tool use, the black-striped capuchin has been shown to use tools in a wide variety of situations, ranging from using rocks for nut cracking to using sticks for digging.[4][5][6][7] They were, until recently, considered a subspecies of the tufted capuchin, but because of more research and insights, they are considered their own species by many.[8]
They often live in highly social groups ranging from 6-20 individuals. Females are philopatric, show coalition, and linear dominance hierarchy.[9] Females reach sexual maturity around 5 years of age and give birth about every 24 months to a single infant.
