Blue-eyed Black Lemurs (IMAGE) National Evolutionary Synthesis Center (NESCent) Caption Blue-eyed black lemurs represent one of the 25 most endangered primates in the world. This infant and his mom are among 27 species of endangered primates at the Duke Lemur Center whose lifelong records are now digitized and available online. Researchers hope the data will help the last blue-eyed black lemurs left in the wild -- now fewer than 7000 -- hold on.
