The ring-tailed lemur (Lemur catta) is a large strepsirrhine primate and the most recognized lemur due to its long, black and white ringed tail. Like all lemurs it is endemic to the island of Madagascar. It inhabits gallery forests to spiny scrub in the southern regions of the island. It is omnivorous and the most terrestrial of extant lemurs. The animal is diurnal, being active exclusively in daylight hours.
