Dancing Lemurs

Taxonomic classification
From a taxonomic standpoint, the term "lemur" originally referred to the genus Lemur, which currently contains only the Ring-tailed Lemur. The term is now used in the colloquial sense in reference to all Malagasy primates.
Lemur taxonomy is controversial, and not all experts agree, particularly with the recent increase in the number of recognized species. According to Russell Mittermeier, the president of Conservation International (CI), taxonomist Colin Groves, and others, there are currently 99 recognized species or subspecies of extant (or living) lemur, divided into five families and 15 genera. Because genetic data indicates that the recently extinct subfossil lemurs were closely related to living lemurs, an additional three families, eight genera, and 17 species can be included in the total. In contrast, other experts have labeled this as taxonomic inflation, instead preferring a total closer to 50 species.
The classification of lemurs within the suborder Strepsirrhini is equally controversial, although the most experts agree on the same phylogenetic tree. In one taxonomy published by Colin Groves, the Aye-aye was placed in its own infraorder, Chiromyiformes, while the rest of the lemurs were placed in Lemuriformes. In another taxonomy, Lemuriformes contains all living strepsirrhines in two superfamilies, Lemuroidea for all lemurs and Lorisoidea for lorises and galagos.
