The wedge-capped capuchin or weeper capuchin is a capuchin monkey from South America.These primates are medium-sized monkeys with distinctive "wedge cap" markings on their head and slightly longer limbs than other capuchins for jumping through the forest canopy. Similar to other capuchin monkeys, the diet of wedge-capped capuchin primarily consists of fruits, invertebrates, other plant parts, and on rare occasions small vertebrates. They have also been known to rub millipedes against their fur, especially in the rainy seasons, as a potential means of mosquito repellent. Although this species is classified as an animal of least concern by IUCN Red List of Threatened Species, it falls prey to many predators in South America ranging from vultures to jaguars.Adult wedge-capped capuchins weight approximately 3 kg, but weight varies moderately with sex. They receive their name from a black triangle of dark fur centered on their foreheads.
