Indriid
The Indriidae (sometimes incorrectly spelled Indridae) are a family of strepsirrhine primates. They are medium- to large-sized lemurs, with only four teeth in the toothcomb instead of the usual six. Indriids, like all lemurs, live exclusively on the island of Madagascar. Classification The 19 living species in the family are divided into three genus, genera.

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 ...

Strepsirrhine
Strepsirrhini or Strepsirhini (; ) is a suborder of primates that includes the lemuriform primates, which consist of the lemurs of Madagascar, galagos ("bushbabies") and pottos from Africa, and the lorises from India and southeast Asia. Collectively they are referred to as strepsirrhines. Also belonging to the suborder are the extinct 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 simians, large olfactory lobes for smell, a vomeronasal organ to detect pheromones, and a bicornuat ...

Woolly Lemur
The woolly lemurs, also known as avahis or woolly indris, are nine species of strepsirrhine primates in the genus ''Avahi''. Like all other lemurs, they live only on the island of Madagascar. With a body size of and a weight of , the woolly lemurs are the smallest indriids. Their fur is short and woolly. The body can be grey brown to reddish, with white on the back of the thighs, with a long, orange tail. The head is round with a short muzzle and ears hidden in the fur. Woolly lemurs can be found in both humid and dry forests, spending most of their time in the leafy copse. Like many leafeaters, they need long naps to digest their food. Woolly lemurs live together in groups of two to five animals, which often consist of parents and several generations of their offspring. Like all indriids, the woolly lemurs are strictly herbivorous, eating predominantly leaves, but also buds and, rarely, flowers. Males and females live in pairs. Although likely, the presence of extrapair cop ... [...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 ...

Golden-crowned Sifaka
The golden-crowned sifaka or Tattersall's sifaka (''Propithecus tattersalli'') is a medium-sized lemur characterized by mostly white fur, prominent furry ears, and a golden-orange crown. It is one of the smallest sifakas (genus ''Propithecus''), weighing around and measuring approximately from head to tail. Like all sifakas, it is a vertical clinger and leaper, and its diet includes mostly seeds and leaves. The golden-crowned sifaka is named after its discoverer, Ian Tattersall, who first spotted the species in 1974. However, it was not formally described until 1988, after a research team led by Elwyn L. Simons observed and captured some specimens for captive breeding. The golden-crowned sifaka most closely resembles the western forest sifakas of the ''P. verreauxi'' group, yet its karyotype suggests a closer relationship with the ''P. diadema'' group of eastern forest sifakas. Despite the similarities with both groups, more recent studies of its karyotype support its cl ... [...More Info...] [...Related Items...] OR: [Wikipedia] [Google] [Baidu] |
Propithecus
A sifaka (; ) is a lemur of the genus ''Propithecus'' from the family Indriidae within the order Primates. The name of their family is an onomatopoeia of their characteristic "shi-fak" alarm call. Like all lemurs, they are found only on the island of Madagascar. All species of sifakas are threatened, ranging from endangered to critically endangered. Anatomy and physiology Sifakas are medium-sized indrids with a head and body length of and a weight of . Their tail is just as long as their body, which differentiates them from the Indri. Their fur is long and silky, with coloration varying by species from yellowish-white to blackish-brown. Their round, hairless face is always black. As with all lemurs, the sifaka has special adaptations for grooming, including a toilet-claw on its second toe and a toothcomb. Sifakas move by vertical clinging and leaping, meaning they maintain an upright position leaping from tree trunk to tree trunk and moving along branches. They are skill ...

Western Woolly Lemur
The western woolly lemur or western avahi (''Avahi occidentalis'') is a species of woolly lemur native to western Madagascar, where they live in dry deciduous forests. These nocturnal animals weigh . It is a folivorous species. The western woolly lemurs live in monogamous pairs together with their offspring. Ecology The Western woolly lemur mostly consumes leaves and buds that derive from around 20 different plants which have not matured and have high levels of sugars and proteins.The Primata. (2007"Western Woolly Lemur (Avahi occidentalis)" Retrieved 2 April 2013.Arkive. (n.d."Western Woolly Lemur (Avahi occidentalis)". Retrieved 3 April 2013. The food is typically consumed within the time frame of two hours before dawn and two hours after dusk, in which the lemurs consume their food at the tops of trees ranging between 2 and 9 metres. During feeding time, lemurs typically settle on thinner branches unless the tree itself is too small to support the animal's weight. Most likely ...

Perrier's Sifaka
Perrier's sifaka (''Propithecus perrieri'') is a lemur endemic to Madagascar. It was formerly considered to be a subspecies of diademed sifaka It has a very small range in northeastern Madagascar where its habitat is dry deciduous or semihumid forest. Part of its range is in protected areas. It is an almost entirely black sifaka and measures about , half of which is a bushy tail. Females are slightly larger than males. It moves in small family groups through the canopy feeding on fruit, leaves, flowers, buds, and seeds. Groups have territories around one hectare and vocalise with each other. The main threats faced by this sifaka are habitat destruction and fragmentation due to slash-and-burn agriculture, charcoal gathering, and logging. The International Union for Conservation of Nature has rated its conservation status as " critically endangered". Description It has a length of 85 to 92 cm, of which 42–46 cm are tail. Its pelage is almost entirely black, covering eve ... [...More Info...] [...Related Items...] OR: [Wikipedia] [Google] [Baidu] |
Milne-Edwards's Sifaka
Milne-Edwards's sifaka (''Propithecus edwardsi''), or Milne-Edwards's simpona, is a large arboreal, diurnal lemur endemic to the eastern coastal rainforest of Madagascar. Milne-Edwards's sifaka is characterized by a black body with a light-colored "saddle" on the lower part of its back. It is closely related to the diademed sifaka, and was until recently considered a subspecies of it. Like all sifakas, it is a primate in the family Indriidae. Conservation status Milne-Edwards's sifaka is categorized as endangered by the IUCN, and is listed in CITES Appendix I. As of 2008 there were estimated to be approximately 28600 individuals left with only about 3500 of those remaining in protected areas. It remains threatened by habitat loss, hunting and may be sensitive to a changing climate. Anatomy and physiology Milne-Edwards's sifaka is the second largest species in ''Propithecus'', and one of the larger diurnal lemur species overall.

Silky Sifaka
The silky sifaka (''Propithecus candidus'') is a large lemur characterized by long, silky, white fur. It has a very restricted range in northeastern Madagascar, where it is known locally as the ''simpona''. It is one of the rarest mammals on Earth. The silky sifaka is one of nine sifaka species (genus ''Propithecus''), and one of four former subspecies of diademed sifaka (''P. diadema''). Studies in 2004 and 2007 compared external proportions, genetics, and craniodental anatomy supporting full species status, which has generally been accepted. The silky sifaka has a variable social structure, and lives in groups of two to nine individuals. It spends most of its day feeding and resting, though it also devotes a considerable amount of time to social behaviors, such as playing and grooming, as well as travelling. Females occasionally take priority over males during feeding. Like other eastern sifakas, it consumes mainly leaves and seeds, but also fruit, flowers, and even so ...

Diademed Sifaka
The diademed sifaka (''Propithecus diadema''), or diademed simpona, is an endangered species of sifaka, one of the lemurs endemic to certain rainforests in eastern Madagascar. Along with the indri, this species is one of the two largest living lemurs, with an average weight of 6.5 kg and a total adult length of approximately 105 centimetres (41 inches), half of which is its tail. Russell Mittermeier, one of the contemporary authorities on lemurs, describes the diademed sifaka as "one of the most colorful and attractive of all the lemurs", having a long and silky coat. ''P. diadema'' is also known by the Malagasy names simpona, simpony and ankomba joby. The term "diademed sifaka" is also used as a group species designation formerly encompassing four distinct subspecies. Description ''P. diadema'' is readily distinguished from all the other lemur species by its characteristic markings and large physical size. Its entire coat is moderately long, silky and luxuriant. ... [...More Info...] [...Related Items...] OR: [Wikipedia] [Google] [Baidu] |
