Lemurs have traditionally been regarded as being less intelligent than anthropoid primates, [129] with monkeys and apes often described as having more cunning, guile, and deceptiveness. [17] Many lemur species, such as sifakas and the ring-tailed lemur, have scored lower on tests designed for monkeys while performing as well as monkeys on other ...

Female dominance amongst lemurs is when the females are sexually monomorphic and have priority access to food. Lemurs live in groups of 11 to 17 animals, where females tend to stay within their natal groups and the males migrate. Male lemurs are competitive to win their mates which causes instability among the other organisms.
In isolation, the lemurs diversified and filled the niches often filled by monkeys and apes today. [14] In Africa, the lorises and galagos diverged during the Eocene, approximately 40 mya. [ 11 ] Unlike the lemurs in Madagascar, they have had to compete with monkeys and apes, as well as other mammals.
Members of this superfamily are called lemuroids, or lemurs. Lemuroidea is one of two superfamilies that form the suborder Strepsirrhini , itself one of two suborders in the order Primates. They are found exclusively on the island of Madagascar , primarily in forests but with some species also in savannas, shrublands, or wetlands.
However, ruffed lemurs were reassigned to the genus Varecia in 1962, [20] and due to similarities between the ring-tailed lemur and the bamboo lemurs, particularly in regards to molecular evidence and scent glands similarities, the true lemurs were moved to the genus Eulemur by Yves Rumpler and Elwyn L. Simons (1988) as well as Colin Groves and ...
Collared brown lemurs: Female (top) and male (bottom) (Illustration from 1892) In the wild, the collared brown lemur's range does not overlap with other brown lemurs, so it is rarely confused with other species. [6] However, in captivity it can be easily confused with the gray-headed lemur (Eulemur cinereiceps) due to similar coloration. The ...
Common brown lemurs are unique amongst Eulemur in that they exhibit little-to-no sexual dichromatism: in both males and females, the face, muzzle and crown are dark gray or black, with white or tan "cheeks" of varying thickness. Some individuals may have pale-colored eyebrow patches, and the eyes are almost always a deep orange-red.
