Lemuridae
Lemuridae is a family of strepsirrhine primates native to Madagascar and the Comoros. They are represented by the Lemuriformes in Madagascar with one of the highest concentration of the lemurs. One of five families commonly known as lemurs. These animals were once thought to be the evolutionary predecessors of monkeys and apes, but this is no longer considered correct. They are formally referred to as lemurids. Classification The family Lemuridae contains 21 extant species in five genera.

Ring-tailed Lemur
The ring-tailed lemur (''Lemur catta'') is a large strepsirrhine primate and the most recognized lemur due to its long, black and white ringed tail. It belongs to Lemuridae, one of five lemur families, and is the only member of the ''Lemur'' genus. Like all lemurs it is endemic to the island of Madagascar and endangered. Known locally in Malagasy as ' (, spelled ' in French) or ', it inhabits gallery forests to spiny scrub in the southern regions of the island. It is omnivorous and the most terrestrial of extant lemurs. The animal is diurnal, being active exclusively in daylight hours. The ring-tailed lemur is highly social, living in groups of up to 30 individuals. It is also female dominant, a trait common among lemurs. To keep warm and reaffirm social bonds, groups will huddle together. The ring-tailed lemur will also sunbathe, sitting upright facing its underside, with its thinner white fur towards the sun. Like other lemurs, this species relies strongly on its sense of ... [...More Info...] [...Related Items...] OR: [Wikipedia] [Google] [Baidu] |
Varecia
The ruffed lemurs of the genus ''Varecia'' are strepsirrhine primates and the largest extant lemurs within the family Lemuridae. Like all living lemurs, they are found only on the island of Madagascar. Formerly considered to be a monotypic genus, two species are now recognized: the black-and-white ruffed lemur, with its three subspecies, and the red ruffed lemur. Ruffed lemurs are diurnal and arboreal quadrupeds, often observed leaping through the upper canopy of the seasonal tropical rainforests in eastern Madagascar. They are also the most frugivorous of the Malagasy lemurs, and they are very sensitive to habitat disturbance. Ruffed lemurs live in multi-male/multi-female groups and have a complex and flexible social structure, described as fission-fusion. They are highly vocal and have loud, raucous calls. Ruffed lemurs are seasonal breeders and highly unusual in their reproductive strategy. They are considered an "evolutionary enigma" in that they are the largest of the exta ...

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 ...

Black-and-white Ruffed Lemur
The black-and-white ruffed lemur (''Varecia variegata'') is an endangered species of ruffed lemur, one of two which are endemic to the island of Madagascar. Despite having a larger range than the red ruffed lemur, it has a much smaller population that is spread out, living in lower population densities and reproductively isolated. It also has less coverage and protection in large national parks than the red ruffed lemur. Three subspecies of black-and-white ruffed lemur have been recognized since the red ruffed lemur was elevated to species status in 2001. Together with the red ruffed lemur, they are the largest extant members of the family Lemuridae, ranging in length from and weighing between . They are arboreal, spending most of their time in the high canopy of the seasonal rainforests on the eastern side of the island. They are also diurnal, active exclusively in daylight hours. Quadrupedal locomotion is preferred in the trees and on the ground, and suspensory behavior is ... [...More Info...] [...Related Items...] OR: [Wikipedia] [Google] [Baidu] |
Strepsirrhini
Strepsirrhini or Strepsirhini (; ) is a Order (biology), suborder of primates that includes the Lemuriformes, lemuriform primates, which consist of the lemurs of Fauna of Madagascar, Madagascar, galagos ("bushbabies") and pottos from Fauna of Africa, Africa, and the lorises from Fauna of India, India and southeast Asia. Collectively they are referred to as strepsirrhines. Also belonging to the suborder are the extinct Adapiformes, adapiform primates which thrived during the Eocene in Europe, North America, and Asia, but disappeared from most of the Northern Hemisphere as the climate cooled. Adapiforms are sometimes referred to as being "lemur-like", although the diversity of both lemurs and adapiforms does not support this comparison. Strepsirrhines are defined by their "wet" (moist) rhinarium (the tip of the snout) – hence the colloquial but inaccurate term "wet-nosed" – similar to the rhinaria of canines and felines. They also have a smaller brain than comparably sized sim ... [...More Info...] [...Related Items...] OR: [Wikipedia] [Google] [Baidu] |
Sanford's Brown Lemur
Sanford's brown lemur (''Eulemur sanfordi''), or Sanford's lemur, is a species of Strepsirrhini, strepsirrhine primate in the family Lemuridae. Sanford's brown lemur was previously considered a subspecies of the common brown lemur (''Eulemur fulvus'') but was raised to full species in 2001. It is named after Leonard Cutler Sanford, a trustee of the American Museum of Natural History. Physical description Sanford's brown lemur is a medium-sized lemur with a head-to-body length of , a tail length of , an overall length of , and a body weight of . Data provided by: Terranova and Coffman, 1997 This species is sexually dichromatic. Males have a gray to brown dorsal coat which darkens as it reaches the hands, feet and base of the tail. Ventral coat is pale gray to brownish-gray and the tail is dark gray. The nose, muzzle and face are black, with the surrounding area solid white or light gray. Features that distinguish this species from the white-fronted brown lemur are the more promin ... [...More Info...] [...Related Items...] OR: [Wikipedia] [Google] [Baidu] |
Collared Brown Lemur
The collared brown lemur (''Eulemur collaris''), also known as the red-collared brown lemur or red-collared lemur, is a medium-sized strepsirrhine primate and one of twelve species of brown lemur in the family Lemuridae. It is only found in south-eastern Madagascar. Like most species of lemur, it is arboreal, moving quadrupedally and occasionally leaping from tree to tree. Like other brown lemurs, this species is cathemeral (active during the day and the night), lives in social groups, primarily eats fruit, exhibits sexual dichromatism, and does not demonstrate female dominance. The species is listed as ''Endangered'' by the International Union for Conservation of Nature (IUCN) and is threatened primarily by habitat loss. Taxonomy Together with the twelve other true lemurs (genus ''Eulemur''), the collared brown lemur (''E. collaris'') is a type of lemur belonging to the family Lemuridae. Collectively, lemurs (infraorder Lemuriformes) are classified as strepsirrhine primate ... [...More Info...] [...Related Items...] OR: [Wikipedia] [Google] [Baidu] |
Primate
Primates are a diverse order of mammals. They are divided into the strepsirrhines, which include the lemurs, galagos, and lorisids, and the haplorhines, which include the tarsiers and the simians (monkeys and apes, the latter including humans). Primates arose 85–55 million years ago first from small terrestrial mammals, which adapted to living in the trees of tropical forests: many primate characteristics represent adaptations to life in this challenging environment, including large brains, visual acuity, color vision, a shoulder girdle allowing a large degree of movement in the shoulder joint, and dextrous hands. Primates range in size from Madame Berthe's mouse lemur, which weighs , to the eastern gorilla, weighing over . There are 376–524 species of living primates, depending on which classification is used. New primate species continue to be discovered: over 25 species were described in the 2000s, 36 in the 2010s, and three in the 2020s. Primates have large bra ...

Gray-headed Lemur
The gray-headed lemur (''Eulemur cinereiceps''), or gray-headed brown lemur, is a medium-sized primate, a cathemeral species of lemur in the family Lemuridae. Until a taxonomic revision in 2008, it was known as the white-collared brown lemur or white-collared lemur (''Eulemur albocollaris''). It lives in south-eastern Madagascar. In 2005, satellite imagery estimates showed approximately of total remaining habitat within its geographic range. It is highly threatened by hunting and habitat loss, and was considered to be among the 25 most endangered primates in 2006–2008. It is currently listed as Critically Endangered by the International Union for Conservation of Nature (IUCN) due to a highly restricted range, and has been named one of "The World's 25 Most Endangered Primates." The gray-headed lemur is only found in southeastern Madagascar, from the Manampatrana River south to the Mananara River.

White-headed Lemur
The white-headed lemur (''Eulemur albifrons''), also known as the white-headed brown lemur, white-fronted brown lemur, or white-fronted lemur, is a species of primate in the family Lemuridae. It is only found in north-eastern Madagascar. It is arboreal and is usually found in rainforest treetops. It was formerly recognised as a subspecies of the common brown lemur (''Eulemur fulvus''). Physical characteristics The white-headed lemur is a medium-sized lemur and has a horizontal posture, which is suited to its way of movement. It has a long furry tail assisting it in maintaining its balance as it lands from leaping at a considerable distance. Males have gray-brown upper parts, with darker lower limbs and tail, paler gray upper parts, gray head and face and a darker crown. Females have redder-brown upper parts, paler underparts and darker feet than males. The cheeks and beards are white, bushy and pronounced in males, reddish-brown and less bushy in females.
