Capuchin monkey

The capuchin monkeys (/ˈkæp(j)ʊtʃɪn, -ʃɪn/) are New World monkeys of the subfamily Cebinae. They are readily identified as the "organ grinder" monkey, and have been used in many movies and television shows. The range of capuchin monkeys includes some tropical forests in Central America and South America as far south as northern Argentina. In Central America, where they are called white-faced monkeys ("carablanca"), they usually occupy the wet lowland forests on the Caribbean coast of Costa Rica and Panama and deciduous dry forest on the Pacific coast.

Capuchins have the largest brain-to-body ratio of any nonhuman primate, as well as complex brain wiring. Their neural complexity is likely related to their sociality and foraging skills. Capuchins have evolved skills to access food that other monkeys cannot — and to mentally map food sources in their territories.
