Physical Description Ring-tailed lemur backs are gray to rosy brown with gray limbs and dark gray heads and necks. They have white bellies. Their faces are white with dark triangular eye patches and a black nose. True to their name, ring-tailed lemurs' tails are ringed with 13 alternating black and white bands. Unlike most other lemurs, ringtails spend 40 percent of their time on the ground. They move quadrupedally along the forest floor. Size The average body mass for adult males is 6 pounds (3 kilograms). Females are usually smaller. Their tails can be up to 2 feet long (61 centimeters). Native Habitat Ring-tailed lemurs live in southwestern Madagascar, in arid, open areas and forests in territories that range from 15 to 57 acres (0.06 to 0.2 square kilometers) in size.
