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 pygmy tarsier has a head-body length of 95 to 105 mm (3.7 to 4.1 in), and weighs less than 57 g (2.0 oz), [citation needed] which makes it smaller and lighter than other tarsier species. Likewise, its ears are also smaller than those of the rest of genus Tarsius. Its fur is tan or buff with predominant grey or brownish red coloring. [6]
Their dental formula is also unique: 2.1.3.3 1.1.3.3 [22] Unlike many nocturnal vertebrates, tarsiers lack a light-reflecting layer (tapetum lucidum) of the retina and have a fovea. The tarsier's brain is different from that of other primates in terms of the arrangement of the connections between the two eyes and the lateral geniculate nucleus ...
The gray mouse lemur (Microcebus murinus), grey mouse lemur or lesser mouse lemur is a small lemur, a type of strepsirrhine primate, found only on the island of Madagascar. Weighing 58 to 67 grams (2.0 to 2.4 oz), it is the largest of the mouse lemurs ( genus Microcebus ), a group that includes the smallest primates in the world.
Tarsius is a genus of tarsiers, small primates native to islands of Maritime Southeast Asia, with almost all of its species found on Sulawesi Island.Until 2010, all tarsier species were typically assigned to this genus, but a revision of the family Tarsiidae restored the generic status of Cephalopachus and created a new genus Carlito.
The pygmy mouse lemur (Microcebus myoxinus), also known as Peters' mouse lemur or dormouse lemur, is a primate weighing only 43–55 g (1.5–1.9 oz); it is the second smallest of the mouse lemurs. [4] Its dorsal side is a rufous-brown colour, and creamy-white ventrally. It lives in dry deciduous forests of western Madagascar.
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 ...
The brown mouse lemur (Microcebus rufus) is a small primate, and like the other mouse lemurs can only be found on the island of Madagascar. They are known also as the rufous mouse lemur, eastern rufous mouse lemur, red mouse lemur, or russet mouse lemur. Its dorsal side is brown or reddish-brown, while ventrally it is a whitish-grey.
