The mouse lemurs are nocturnal lemurs of the genus Microcebus.Like all lemurs, mouse lemurs are native to Madagascar. [4]Mouse lemurs have a combined head, body and tail length of 20–30 centimetres (7.9–11.8 in) and weigh 30–65 grams (1.1–2.3 oz), [5] making them the smallest primates [6] (the smallest species being Madame Berthe's mouse lemur); however, their weight fluctuates in ...

Tarsiers (/ ˈ t ɑːr s i ər z / TAR-see-ərz) are haplorhine primates of the family Tarsiidae, which is, itself, the lone extant family within the infraorder Tarsiiformes.Although the group was, prehistorically, more globally widespread, all of the species living today are restricted to Maritime Southeast Asia, predominantly in Brunei, Indonesia, Malaysia and the Philippines.
Primates range in size from the 30-gram (1 oz) pygmy mouse lemur to the 200-kilogram (440 lb) mountain gorilla. According to fossil evidence, the primitive ancestors of primates may have existed in the late Cretaceous period around 65 mya (million years ago), and the oldest known primate is the Late Paleocene Plesiadapis , c. 55–58 mya.
Prosimians contain two monophyletic groups (the suborder Strepsirrhini, or lemurs, lorises and allies, as well as the tarsiers of the suborder Haplorhini); it is a paraphyletic grouping because it excludes the Simiiformes, which also are descendants of the common ancestor Primates.
The lemurs show no obvious morphological differences, but are in communities separated geographically by rivers. [11] Palu tarsier (Tarsius lariang), a new species of tarsier. Jolly’s mouse lemur (Microcebus jollyae), a new species of mouse lemur. Simmons’ mouse lemur (Microcebus simmonsi), a new species of mouse lemur.
Generally accepted members of this infraorder include the living tarsiers, [1] the extinct omomyids, two extinct fossil genera, and two extinct fossil species within the genus Tarsius. [3] As haplorhines, they are more closely related to monkeys and apes than to the strepsirrhine primates, which include lemurs, galagos, and lorises. Order Primates
The Madame Berthe's mouse lemur population is sparse and spread out over a more widespread area; while the gray mouse lemurs had a much denser population in a smaller area. [7] The reason for the mouse lemur species' mutual avoidance is not yet clearly known. The gray mouse lemur has several competitive advantages over Madame Berthe's mouse ...
