Propithecus
A sifaka (; ) is a lemur of the genus ''Propithecus'' from the family Indriidae within the order Primates. The common name 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 indriids 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 skillful climber ...

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 soi ...

Coquerel's Sifaka
Coquerel's sifaka (''Propithecus coquereli'') is a Diurnality, diurnal, medium-sized lemur of the sifaka genus ''Sifaka, Propithecus''. It is native to northwest Madagascar. Coquerel's sifaka was once considered a subspecies of Verreaux's sifaka but was eventually granted full species status. It is listed as Critically Endangered on the IUCN Red List due to habitat loss and hunting. In popular culture, the title character in the children's TV show ''Zoboomafoo'' is a Coquerel's sifaka. The species was named after French entomologist Charles Coquerel. Description The dorsal pelage and tail of Coquerel's sifaka are white, and it has maroon patches on the chest and portions of the limbs. The coat is generally dense. Its face is bare and black except for a distinctive patch of white fur along the bridge of the nose. Its naked ears are also black, and its eyes are yellow or orange. The bottom of the lemur's hands and feet are black, while the thighs, arms, and chest are chocolate br ... [...More Info...] [...Related Items...] OR: [Wikipedia] [Google] [Baidu] |

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] |
Milne-Edwards's Sifaka
Milne-Edwards's sifaka (''Propithecus edwardsi''), or Milne-Edwards's simpona, is a large arboreal, Diurnal animal, diurnal lemur endemic (ecology), endemic to the Madagascar lowland forests, 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 (biology), family Indriidae. The species' name honors French zoologist Henri Milne-Edwards (1800–1885). 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 28,600 individuals left with only about 3,500 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 ...

Lemur
Lemurs ( ; from Latin ) 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 Endemism, 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. Living lemurs range in weight from the mouse lemur to the indri. Since the arrival of humans on the island around 2,000 years ago, over a dozen species of "giant lemurs" larger than living lemur species have become extinct, including the gorilla-sized ''Archaeoindris''. Lemurs share ma ... [...More Info...] [...Related Items...] OR: [Wikipedia] [Google] [Baidu] |
Indriidae
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 genera. Family Indriidae *Genus ''Indri'' **Indri, ''Indri indri'' *Genus '' Avahi'', woolly lemurs ** Bemaraha woolly lemur, ''Avahi cleesei'' ** Eastern woolly lemur, ''Avahi laniger'' ** Moore's woolly lemur, ''Avahi mooreorum'' ** Western woolly lemur, ''Avahi occidentalis'' ** Sambirano woolly lemur, ''Avahi unicolor'' ** Peyrieras's woolly lemur, ''Avahi peyrierasi'' ** Southern woolly lemur, ''Avahi meridionalis'' ** Ramanantsoavana's woolly lemur, ''Avahi ramanantsoavani'' ** Betsileo woolly lemur, ''Avahi betsileo'' *Genus '' Propithecus'', sifakas **''Propithecus diadema'' group *** Diademed sifaka, ''Propithecus diadema'' *** ...

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 ever ... [...More Info...] [...Related Items...] OR: [Wikipedia] [Google] [Baidu] |
Fossa (animal)
The fossa (''Cryptoprocta ferox''; or ; ) is a slender, long-tailed, cat-like mammal that is endemic to Madagascar. It is a member of the carnivora, carnivoran family Eupleridae. The fossa is the largest mammalian carnivore on Madagascar and has been compared to a small cougar, as it has Convergent evolution, convergently evolved many cat-like features. Adults have a head-body length of and weigh between , with the males larger than the females. It has semi-retractable claws (meaning it can extend but not retract its claws fully) and flexible ankles that allow it to climb up and down trees head-first, and also support jumping from tree to tree. A larger relative of the species, ''Cryptoprocta spelea'', probably became extinct before 1400. The species is widespread, although population density, population densities are usually low. It is found solely in forested habitat, and actively hunts both by day and night. Over 50% of its diet consists of lemurs, the endemic primates f ...

Indri
The indri (; ''Indri indri''), also called the babakoto, is one of the largest living lemurs, with a head-body length of about and a weight of between . It has a black and white coat and maintains an upright posture when climbing or clinging. It is monogamous and lives in small family groups, moving through the canopy, and is herbivorous, feeding mainly on leaves but also seeds, fruits, and flowers. The groups are quite vocal, communicating with other groups by singing, roaring and other vocalisations. Besides humans, it is the only mammal found that can use rhythm. It is a Diurnal animal, diurnal tree-dweller related to the sifakas and, like all lemurs, it is native to Madagascar. It is revered by the Malagasy people and plays an important part in their myths and legends with various stories in existence accounting for its origin. The main threats faced by the indri are habitat destruction and fragmentation due to slash and burn agriculture, fuelwood gathering, and logging. It ...

Toothcomb
A toothcomb (also called a tooth comb or dental comb) is a Dentition, dental structure found in some mammals, comprising a group of front teeth arranged in a manner that facilitates grooming, similar to a hair comb. The toothcomb occurs in Lemuriformes, lemuriform primates (which include lemurs and Lorisoidea, lorisoids), treeshrews, colugos, hyraxes, and some African antelopes. The structures evolved independently in different types of mammals through convergent evolution and vary both in dental composition and structure. In most mammals the comb is formed by a group of teeth with fine spaces between them. The toothcombs in most mammals include incisors only, while in lemuriform primates they include incisors and Canine tooth, canine teeth that tilt forward at the front of the lower jaw, followed by a canine-shaped first premolar. The toothcombs of colugos and hyraxes take a different form with the individual incisors being serrated, providing multiple wikt:tine, tines per toot ...
