|Ring tailed lemur|
|Distribution of Lemur catta|
This lemur weighs between 2 to 3.5 kilograms (4.4 to 7.7 lb). It can live up to 20 years.  It is a mid-sized lemur. The striped tail makes it easy to recognize. Its behaviour is somewhat unusual for lemurs: it is active during the day, and spends much time on the ground. Ring-tailed lemurs live in groups of 12 to 15 animals. Each group is led by a female. Ring-tailed lemurs eat both meat and plants, but they mainly eat fruit. They live only in Madagascar. The main threats to ring-tailed lemurs are destroying the places where it lives and hunting.
- The genus name Prosimia was declared unavailable by the International Commission on Zoological Nomenclature in 1998.
- Type species was designated as Catta mococo (= Lemur catta Linnaeus, 1758).
- Type species was designated as Maki mococo (= Lemur catta Linnaeus, 1758).
- The synonym Mococo is sometimes omitted because it was technically a vernacular term for the genus Prosimia. René Primevère Lesson named the type species for this genus as Prosimia catta (= Lemur catta Linnaeus, 1758) in the same year (1878).
- Muirhead (1819) credited the name Maki mococo to Anselme Gaëtan Desmarest (1817), although it was actually used as a vernacular name.
