The ring-tailed lemur (Lemur catta) is the most internationally-recognized lemur species, owing to its long, black-and-white, ringed tail. Like all lemurs, it is endemic to the island of Madagascar, where it is endangered. It ranges from gallery forests to spiny scrub in the southern regions of the island. The ring-tailed lemur is highly social, living in groups of up to 30 individuals. It is also a female-dominant species, a commonality among lemurs. To keep warm and reaffirm social bonds, groups will huddle together. Mutual grooming is another vital aspect of lemur socialization.
