Famous for their lengthy tails, the ring-tailed lemur is a primate found exclusively on the island of Madagascar. Like other lemur species, the ring-tailed lemur is female dominant, meaning that their social groups are controlled by a hierarchy of females.History: Although it is one of the most common lemur species found in zoos, the ring-tailed lemur’s population in the wild is severely threatened from habitat destruction. Despite being a protected species, the ring-tailed lemur’s relatively small range of suitable environments makes it uniquely susceptible to fragmentation and habitat loss. Scientific Name: Lemur cattaCharacteristics: Despite its size, the ring-tailed lemur’s tail is not prehensile, meaning it can’t hold or grasp objects, and is instead used primarily for balance and communication. Size: Standing 4 inches tall and 3 inches long.
