The Ring-tailed Lemur (Lemur catta) is a large Strepsirhine primate and the most recognized lemur due to its long, black and white ringed tail. It belongs to Lemuridae, one of four lemur families. It is the only member of the Lemur genus. Like all lemurs it is endemic to the island of Madagascar. Known locally as Hira (Malagasy) or Maki (French and Malagasy), it inhabits gallery forests to spiny scrub in the southern regions of the island. It is omnivorous and the most terrestrial of lemurs. The animal is diurnal, being active exclusively in daylight hours.

The Ring-tailed Lemur is highly social, living in groups of up to 30 individuals. It is also female dominant, a trait common among lemurs but uncommon among other primates. To keep warm and reaffirm social bonds groups will huddle together forming a lemur ball. The Ring-tailed Lemur will also sunbathe, sitting upright facing its underside, with its thinner white fur towards the sun. Like other lemurs, this species relies strongly on its sense of smell and marks its territory with scent glands. The males perform a unique scent marking behavior called spur marking and will participate in stink fights by impregnating their tail with their scent and wafting it at opponents
