Lemur catta

The lemur catta, also known as katta or ring-tailed lemur, is a medium to large sized lemur of the Lemuridae family, and is the only extant of the genus lemur. By far the most known lemur due to its long, white and black ringed tail, like all lemurs it is endemic to Madagascar, where it inhabits gallery forests and spiny scrubs of the central and southern part of the island. The lemur catta is omnivorous and, although able to climb, is considered the most terrestrial among lemurs.
It is highly social and forms large groups that can count up to 30 members. Females are dominant. In order to strengthen social bonds and to maintain body heat, the members of the same herd are often gathered closely together.
It is a diurnal animal. During the day the lemur catta is used to sunbathe, often in a sitting position. The ring-tailed lemur has great ability to vocalize and uses various vocalizations to maintain the group cohesion or to alert the other individuals of a threat. Average life expectancy is about 18 years (27 in captivity).
