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.
Ruffed lemurs are typically described as multi-male groups with a fission-fusion social structure, [11] [13] [19] although this can vary by season and locality. [11] In a study done at Masoala Peninsula on red ruffed lemurs three levels of organization were identified and defined: communities, core groups, and subgroups.
This demonstrates that lemur species such as the lemur catta and the common brown lemur were forced to switch their primary diet to a group of secondary food sources. [ 9 ] With most lemurids, the mother gives birth to one or two young after a gestation period of between 120 and 140 days, depending on species.
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.

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]
The Nocturnal Lemurs booklet contains 65 species from eight genera. [9] Diurnal and Cathemeral Lemurs hosts 34 species and subspecies from seven genera, along with illustrations to show male and female fur color differences in the genus Eulemur and color morphs for the indri and ruffed lemur species.
