The Ring-tailed Lemur is a relatively large prosimian, a lemur belonging to the family Lemuridae. Ring-tailed Lemurs are the only species within the genus Lemur and are found only on the island of Madagascar. Although threatened by habitat destruction in their native forests, Ring-tailed Lemurs are the most populous lemurs in zoos worldwide; in part because they reproduce readily in captivity.
