Today we celebrate International Primate Day. More than a day to celebrate these fascinating mammals, this is an opportunity to raise awareness of the urgent need to protect primate species and their homes: our forests.
Cebus kaapori is one of the clearest examples of primates that urgently need our attention and conservation efforts. Endemic to Brazil and extremely rare, the species is classified as Critically Endangered by the IUCN and has been included in the list of the 25 most endangered primates in the world.
Found in the Arc of Deforestation in the Eastern Amazon, Cebus kaapori is primarily threatened by the region’s long history of forest destruction. This region has the highest human population density and the highest levels of deforestation and habitat degradation in the entire Brazilian Amazon.
On International Primate Day, Cebus kaapori reminds us that celebrating primates also means taking action for their conservation.
