Endangered inhabitants of Madagascar, Ring-tailed lemurs move about trees day or night, yet they spend more time on ground than other lemurs, moving on all fours. A grey back, white under parts, a white fox-like face with dark brown eye patches, and distinctive black and white ringed-tail characterize them. They live in spiny desert, dry forests, and scrubland and eat 70% fruit supplemented with leaves, bark, sap and flowers. Their life span is 27 years.
