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.
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.
Smithsonian’s National Zoo and Conservation Biology Institute recently shared a video of three lemur babies who came into the world on April 5.

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 ]
Three subspecies of black-and-white ruffed lemur have been recognized since the red ruffed lemur was elevated to species status in 2001. [5] Together with the red ruffed lemur, they are the largest extant members of the family Lemuridae, ranging in length from 100 to 120 cm (3.3 to 3.9 ft) and weighing between 3.1 and 4.1 kg (6.8 and 9.0 lb).
Locomotor postures and behaviors have included vertical clinging and leaping (including saltatory behavior), seen in indriids and bamboo lemurs; [38] [65] slow (loris-like) arboreal quadrupedal locomotion, once exhibited by Mesopropithecus; [111] fast arboreal quadrupedal locomotion, seen in true lemurs and ruffed lemurs; [38] [112] partially ...
