The white-faced capuchin (Cebus imitator). The name capucin derives from the order of monks called minor capuchin who shaved the top of their head and wore a small round cap (zuchetto). After apes, capuchins stand out with their remarkable intelligence among primates. They are known for tools, rubbing into their fur some plants in order to prevent parasites and fungi. Capuchins like most primates are important seed dispersers. They also fulfill the function of pollinators to some plants when they lick nectar or pollen. They live in groups of up to 20 individuals building advanced social structures. Their life span is about 50 years. Their intelligence is one reason of using them by humans in entertainment industry and scientific experiments.
