Ring-tailed lemurs are perhaps the most easily recognized of all the lemur species. King Julien in the movie Madagascar is an example of one! Ring-tailed lemurs are unique from other lemurs in that they prefer walking on the ground to swinging through trees. Lemurs are noisy, making 15 different kinds of sounds from purrs to clicks to grunts to howls. Orbit and Ringer are the most vocal at the sanctuary, but no competition to their ruffed lemur neighbors!
