Cheirogaleus
The dwarf lemurs are the lemurs of the genus ''Cheirogaleus''. All of the species in this genus, like all other lemurs, are native to Madagascar. Description Measuring 19–27 cm in body length with a tail about 16–17 cm, they are larger than the mouse lemur but smaller than the gentle lemur. Their heads are globular compared to the fox-like heads of the lemurs, but their muzzles are more pointed than those of the hapalemurs. Their hind limbs are slightly longer than their forelimbs, but not as elongated as in lepilemurs or indriids. Dwarf lemurs have an intermembral index of 71 on average. In contrast to most other primates, their grip is similar to that of South American monkeys with objects picked up and branches grasped between the second and third fingers, rather than between the thumb and index finger. Their nails are somewhat keeled and pointed. Dwarf lemurs roam the lower strata of the foliage in the coastal forests of eastern Madagascar. They a ...

Greater Dwarf Lemur
The greater dwarf lemur (''Cheirogaleus major''), or the Geoffroy's dwarf lemur, is a lemur that is widely distributed over the primary and secondary forests near the eastern coast of Madagascar. They are also found in northern parts of Madagascar. Greater dwarf lemurs live in forests and dry scrub areas. The head and body of the greater dwarf lemur can range from 167 to 264 millimeters in length, and 164 to 600 grams. Their tails can range from 195 to 310 millimeters in length.Cooper, A. 2000. "Cheirogaleus major" (On-line), Animal Diversity Web. Accessed July 25, 2012 at http://animaldiversity.ummz.umich.edu/site/accounts/information/Cheirogaleus_major.html Greater dwarf lemurs are nocturnal. During the day, they sleep in nests of twigs, leaves, and grass, or hollowed sections of trees padded with dry leaves. Their diet consists mostly of fruits, flowers, and nectar. Flower nectar is an important part of the diet from November to December. Sometimes they will also eat insects a ... [...More Info...] [...Related Items...] OR: [Wikipedia] [Google] [Baidu] |
Fat-tailed Dwarf Lemur
The fat-tailed dwarf lemur (''Cheirogaleus medius''), also known as the lesser dwarf lemur, western fat-tailed dwarf lemur, or spiny forest dwarf lemur, is endemic to Madagascar. Hibernation Recent research has shown that ''C. medius'' hibernates (or aestivates), even though in the tropical winter of Madagascar, temperatures remain high. It is the first tropical mammal and only primate in which hibernation has been demonstrated. However, the Malagasy winter is dry, and it appears that the lemur is avoiding the drought. It can hibernate for seven months. Unlike animals that hibernate in temperate regions, the lemur does not control its body temperature while hibernating, and if the tree hole in which it is sleeping is not well insulated, its body temperature fluctuates in accordance with the outside temperature. During torpor, this lemur has been found to periodically enter REM sleep; non-REM sleep has not been observed, a pattern opposite that found in hibernating ground squirre ...

Groves' Dwarf Lemur
Groves' dwarf lemur (''Cheirogaleus grovesi'') is a species of dwarf lemur known from Ranomafana and Andringitra national parks and surrounding areas in southeastern Madagascar. The identification was based on comparison of mitochondrial and nuclear gene sequences with other members of the ''C. crossleyi'' group ('' C. andysabini'', '' C. crossleyi'', '' C. lavasoensis'' and an unnamed possible new species, "CCS2"). Individuals from this clade first came under genetic study in 1999 and were recognized as a new species in 2014, but it was not formally described until 2017. The lemur was named after mammalologist Colin Groves. Known from altitudes from 754 to 999 m, it is significantly larger than other members of the ''C. crossleyi'' group, with a 20 cm body length, a 29 cm tail, and a weight of 0.41 kg. While the conservation status of the new species has not yet been assessed, its presence in several national parks does not guarantee that it will not be threatened by deforesta ...

List Of Mammals Of Madagascar
This is a list of the native wild mammal species recorded in Madagascar. As of June 2014 (following the IUCN reassessment of the lemurs) there are 241 extant mammal species recognized in Madagascar, of which 22 are critically endangered, 62 are endangered, 32 are vulnerable, 9 are near threatened, 72 are of least concern and 44 are either data deficient or not evaluated. All of the critically endangered species are lemurs. The mammalian fauna of Madagascar is highly distinctive and largely endemic. The extant nonmarine, nonchiropteran taxa constitute (as of June 2014) 168 species, 40 genera and 9 families; of these, besides a probably introduced shrew, endemic taxa make up all the species, all the genera, and all but one of the families. This endemic terrestrial fauna, consisting of lemurs, tenrecs, nesomyine rodents and euplerid carnivorans, is thought to have colonized the island from Africa via four (or five, if aye-ayes arrived separately) rafting events.

Furry-eared Dwarf Lemur
The furry-eared dwarf lemur (''Cheirogaleus crossleyi''), or Crossley's dwarf lemur, only found on the island of Madagascar, as with all other lemurs. It has a pelage Fur is a thick growth of hair that covers the skin of mammals. It consists of a combination of oily #Guard hair, guard hair on top and thick #Down hair, underfur beneath. The guard hair keeps moisture from reaching the skin; the underfur acts as ... coloration that is red-brown dorsally and gray ventrally. The eye-rings of this species are blackish and the ears are black inside and out. ''Cheirogaleus crossleyi'' species are obligated to hibernate during periods of food scarcity on the island of Madagascar. ''Cheirogaleus crossleyi'' species specifically undergo drastic fluctuations in temperature during hibernation.

Lavasoa Dwarf Lemur
The Lavasoa dwarf lemur (''Cheirogaleus lavasoensis'') is a small, nocturnal strepsirrhine primate and a species of lemur that is endemic to three small, isolated patches of forest on the southern slopes of the Lavasoa Mountains in southern Madagascar. Fewer than 50 individuals are thought to exist. Its habitat lies in a transitional zone between three ecoregions: dry spiny bush, humid littoral forest, and humid forest. First collected in 2001 and thought to be a subpopulation of the furry-eared dwarf lemur (''C. crossleyi''), it was not formally described until 2013. It is one of six species of dwarf lemur, though the research that identified it also suggested the existence of many more new species. Taxonomic history The Lavasoa dwarf lemur belongs to the genus ''Cheirogaleus'' (dwarf lemurs) within the family Cheirogaleidae. Between October 2001 and December 2006, researchers collected ten mature adults (five male and five female) along with six immature individua ...

Lesser Iron-gray Dwarf Lemur
The lesser iron-gray dwarf lemur (''Cheirogaleus minusculus''), or large iron-gray dwarf lemur, is a small nocturnal lemur endemic to Madagascar. It is nocturnal and an arboreal quadruped, and is not very agile. It produces three types of vocalisation: a squeak, which is high in pitch and is produced with the mouth closed, and is used between infants and their mothers; a whistle, which is higher in pitch than the squeak, so it is hard to hear with human ears, and is used as a communicative and possibly territorial call; and a grunt, which is usually given in series and is very powerful, used when an individual is being attacked in its nest. This species is only known to exist from one museum specimen from Ambositra Ambositra is a city (commune urbaine) in central Madagascar.

Ankarana Dwarf Lemur
The Ankarana dwarf lemur or Sheth's dwarf lemur (''Cheirogaleus shethi'') is a species of dwarf lemur, part of the ''C. medius'' group, known only from northern Madagascar. It has been found in two reserves (Ankarana Special Reserve and Analamerana Special Reserve) as well as two protected areas (Andrafiamena-Andavakoera and Loky-Manambato). It was identified in 2014, but not formally described until 2016. Its conservation status has not been determined, but it is at risk from habitat destruction Habitat destruction (also termed habitat loss and habitat reduction) is the process by which a natural habitat becomes incapable of supporting its native species. The organisms that previously inhabited the site are displaced or dead, thereby ... due to daily resource extraction by local human populations.

Lemur
Lemurs ( ) (from Latin ''lemures'' – ghosts or spirits) are Strepsirrhini, wet-nosed primates of the Superfamily (biology), superfamily Lemuroidea (), divided into 8 Family (biology), families and consisting of 15 genera and around 100 existing species. They are endemic to the island of Madagascar. Most existing lemurs are small, have a pointed snout, large eyes, and a long tail. They arboreal, chiefly live in trees and nocturnal, are active at night. Lemurs share resemblance with other primates, but evolved independently from monkeys and apes. Due to Madagascar's highly seasonal climate, Evolution of lemurs, lemur evolution has produced a level of species diversity rivaling that of any other primate group. Until shortly after humans arrived on the island around 2,000 years ago, there were lemurs as large as a male gorilla. Most species have been discovered or promoted to full species status since the 1990s; however, lemur Taxonomy (biology), taxonomic classification is ...
