World's Top 25 Most Endangered Primates

New List of the World's Top 25 Most Endangered Primates

In August of 2008, a special open meeting of primatologists and conservationists convened at the 22nd Congress of the International Primatological Society in Edinburgh, Scotland. Based on the discussions at that meeting, a new list of the world's most endangered primates has been drawn up, in order to highlight the severe dangers facing primate species worldwide.
