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 ...
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.
The order Primates consists of 505 extant species belonging to 81 genera. This does not include hybrid species or extinct prehistoric species. Modern molecular studies indicate that the 81 genera can be grouped into 16 families; these families are divided between two named suborders and are grouped in those suborders into named clades, and some of these families are subdivided into named ...
Prosimian tarsiers in the family Tarsiidae (monotypic in its own infraorder Tarsiiformes), represent the most basal division, originating about 58 mya. [48] [49] The earliest known haplorhine skeleton, that of 55 MA old tarsier-like Archicebus, was found in central China, [50] supporting an already suspected Asian origin for the group. [51]
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.
Weighing 58 to 67 grams (2.0 to 2.4 oz), it is the largest mouse lemur, yet smaller than the world's smallest monkey, the pygmy marmoset, which ranges between 85 and 140 g (3.0 and 4.9 oz). Its genus, Microcebus, includes the smallest primates in the world. The gray mouse lemur is named for its mouse-like size and coloration
The pygmy tarsier (Tarsius pumilus), also known as the mountain tarsier or the lesser spectral tarsier, is a nocturnal primate found in central Sulawesi, Indonesia, in an area with lower vegetative species diversity than the lowland tropical forests. The pygmy tarsier was believed to have become extinct in the early 20th century.
Madame Berthe's mouse lemur (Microcebus berthae) or Berthe's mouse lemur is the smallest of the mouse lemurs and the smallest primate in the world; the average body length is 9.2 cm (3.6 in) and seasonal weight is around 30 g (1.1 oz). [4]
