Capuchins generally resemble the friars of their namesake. Their body, arms, legs, and tail are all darkly (black or brown) colored, while the face, throat, and chest are white colored, and their heads have a black cap. The long hairy tail is partly prehensile. It serves as an anchor or prop when Capuchin Monkeys travel through the trees. Capuchin Monkeys reach a length of 30 to 56 centimetres (12 - 22 inches), with tails that are just as long as their body. Capuchin Monkeys weigh up to 1.3 kilograms (2 - 3 pounds), with brains of mass 35 - 40 grams. They are considered the most intelligent New World monkeys.
