Weeper capuchin

(Cebus olivaceus)



weeper capuchin (Cebus olivaceus) is a capuchin monkey from South America.It is found in northern Brazil,Guyana,French Guiana,Suriname,Venezuela and possibly northern Colombia.The genus Cebus is divided into several different species.However,taxonomists argue over the specific divisions within the genus,which are uncertain and controversial.Cebus olivaceus is known to dwell in tall,primary forest and travel over long distances during the day.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.Generally this species is light brown to brown with yellow and gray tinges on varying parts of their bodies.Their “wedge cap” starts between the eyes and extends backwards to cover the top of the head.Their faces are hairless and surrounded by light brown or blonde fur.Wedge-capped capuchins show similar levels of sexual dimorphism as other capuchin monkeys.On average,males weigh about 30% more than females.Additionally,males have relatively longer canines than females (even after overall body size is accounted for).Male maxillary and mandibular (upper and lower) canines of males are on average 70% and 40% larger than female canines respectively.This may be indicative of male competition for females.
