The ring-tailed lemur is a large strepsirrhine primate. It belongs to Lemuridae, one of five lemur families. Like all lemurs, it is endemic to Madagascar, living in the gallery forests and spiny scrubland in the southern regions of the island. It is omnivorous, diurnal and highly social, living in groups of up to 30 individuals. Communities are matriarchal, a trait common among lemurs. Like other lemurs, this species relies strongly on its sense of smell and marks its territory with scent glands. As one of the most vocal primates, the ring-tailed lemur uses numerous vocalizations such as alarm calls. Experiments have shown that, despite the lack of a large brain, the ring-tailed lemur can organize sequences, understand basic arithmetic operations and preferentially select tools based on functional qualities. Despite being listed as Near Threatened by the IUCN Red List and suffering from habitat destruction, the ring-tailed lemur reproduces readily in captivity and is the most populous lemur in zoos worldwide, numbering more than 2000 individuals. It typically lives 16 to 19 years in the wild and 27 years in captivity. (more...)
