Red ruffed lemurs grooming each other. The red ruffed lemur is a very clean animal and spends a lot of time grooming itself and in social grooming. The lower incisors (front teeth) and the claw on the second toe of the hind foot are specially adapted for this behavior. The lower incisors grow forward in line with each other and are slightly spaced.
Lemuridae contains 21 ruffed, ring-tailed, bamboo, and other lemur species in five genera. Lepilemuridae contains 25 sportive lemur species in a single genus. Dozens of extinct prehistoric lemuroid species have been discovered, though due to ongoing research and discoveries the exact number and categorization is not fixed. [ 1 ]
Ruffed lemurs are typically described as multi-male groups with a fission-fusion social structure, [12] [14] [20] although this can vary by season and locality. [12] In a study done at Masoala Peninsula on red ruffed lemurs three levels of organization were identified and defined: communities, core groups, and subgroups.
Smithsonian’s National Zoo and Conservation Biology Institute recently shared a video of three lemur babies who came into the world on April 5.

The red lemur (Eulemur rufus), also known as the rufous brown lemur or northern red-fronted lemur, is a species of lemur from Madagascar. Until 2001, the species E. rufus was considered a subspecies of the common brown lemur , E. fulvus , [ 4 ] after which it was classified as its own species.
The order Primates consists of 505 extant species belonging to 81 genera. This does not include hybrid species or extinct prehistoric species. Modern molecular studies indicate that the 81 genera can be grouped into 16 families; these families are divided between two named suborders and are grouped in those suborders into named clades, and some of these families are subdivided into named ...
Species that park their offspring include nocturnal species (e.g. mouse lemurs, sportive lemurs, and dwarf lemurs), bamboo lemurs, and ruffed lemurs. [29] [125] In the case of the ruffed lemurs, the young are altricial and the mothers build nests for them, much like the smaller, nocturnal lemur species. [2]
