Kaapori capuchin
[2] After analyzing their genetic makeup, researchers Harada and Ferrari argued that the Ka'apor capuchins should be considered a subspecies of the latter.[3][5] They also have rounder skulls as well as differences in their teeth and jaws which renders them incapable of opening hard nuts like their robust counterparts.[3][7][5] In one study, researchers following a group of C. kaapori observed that their average daily travel was of approximately 2,175 m and utilized most quadrants of their home range every month.[3] From their research, the scientists concluded that the Ka'apor capuchins' diet resembles most closely that of the Sapajus genera than their fellow Cebus species.[3] The species is generally found living in small groups of less than 10 individuals, sometimes even alongside bearded sakis or robust capuchins.[7] One major concern for conservation of the species is the fact that so little standardized research has been done on the topic thus, in order to be able to protect them adequately we need to understand them more thoroughly.
