Kaapori capuchin

The Kaapori capuchin (Cebus kaapori), also written Ka'apor capuchin, is a frugivorous gracile capuchin endemic to the Brazilian Amazon, in the states of Pará and Maranhão. Helder Queiroz described it in 1992, and it was long treated as a subspecies before morphological and molecular evidence led to its recognition as a species in its own right. It has one of the smallest ranges of any Cebus species and lives in isolated patches of tall lowland terra firme forest in the most densely populated region of the Amazon, so it is rare even within its range. It is diurnal, arboreal and omnivorous, and a field study found that almost 75 percent of its diet was fruit matter. It is one of the most endangered of the neotropical primates.
