Naples Zoo recently announced the birth of two endangered ring-tailed lemurs, born on March 25. Parents PJ and Julien were genetically matched by the Association of Zoos and Aquariums’ cooperatively managed Species Survival Plan program, designed to maintain a healthy, genetically diverse and demographically stable population for the long-term future. One year ago, PJ and Julien welcomed baby Velo, and now they will add two more babies to their troop.
