black lemur
The black lemur (''Eulemur macaco'') is a species of lemur from the family Lemuridae. Like all lemurs, it is endemic to Madagascar. Originally, the species was thought to have two subspecies, ''Eulemur macaco macaco'' and ''Eulemur macaco flavifrons'', both of which were elevated to species status by Mittermeier ''et al.'' in 2008 to ''Eulemur macaco'' and ''Eulemur flavifrons'' respectively.〔 The most startling difference between the two species is the eye colour; ''Eulemur flavifrons'', the blue-eyed black lemur, has blue eyes and is the only primate other than humans to have blue eyes, while ''Eulemur macaco'', the black lemur, has brown or orange eyes, and also has ear tufts.
Both species live in northwest Madagascar. The black lemur occurs in moist forests in the Sambirano region of Madagascar and on nearby islands.〔 The blue-eyed black lemur is restricted to the Sahamalaza Peninsula and adjacent forests.〔 There are reports of the two species hybridizing where their ranges overlap in Manongarivo Special Reserve.
== Physical description ==
The black lemur is between 90 and 110 centimeters in length, of which 51-65 centimeters are tail.〔 Weight typically ranges between 1.8 and 2.0 kilograms.〔 The black lemur displays sexual dimorphism in coloration. Males have black or dark chocolate fur, while females' fur is of a lighter brown color, generally medium brown, chestnut brown or even orange-brown.〔 Males have large black ear tufts, while females have large white ear tufts.
The only other ''Eulemur'' species that occurs within the range of the black lemur is the common brown lemur, which overlaps with the black lemur at the extreme southern and eastern edge of its range,〔 and the red-bellied lemur, on the Tsaratanana Massif.〔 The common brown lemur and the red-bellied lemur have different coloration and do not show the extreme sexual dimorphism of the black lemur, making confusion between the black lemur and the other species unlikely.〔〔
