Indriids
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.

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 ...

Gilbert Thomas Burnett
Gilbert Thomas Burnett (15 April 1800 – 27 July 1835) was a British botanist. Burnett was the first professor of botany at King's College London, from 1831 to 1835. He was the author of ''Outlines of Botany'' (1835), and ''Illustrations of Useful Plants employed in the Arts and Medicine'', published posthumously and illustrated by his sister Mary Ann Burnett. Burnett also wrote articles on zoology, such as ''Illustrations of the Manupeda or apes and their allies'' (1828).

Bemaraha Woolly Lemur
The Bemaraha woolly lemur (''Avahi cleesei''), also known as Cleese's woolly lemur, is a species of woolly lemur native to western Madagascar, named after John Cleese. The first scientist to discover the species named it after Cleese, star of Monty Python, mainly because of Cleese's fondness for lemurs, as shown in '' Operation Lemur With John Cleese'' and ''Fierce Creatures'', and his efforts at protecting and preserving them. The species was first recorded in 1990 by a team of scientists from Zurich University led by Urs Thalmann, but wasn't formally described as a species until November 11, 2005. The diurnal animal weighs about , has brown skin with white regions on the rear and inside of the thighs and has a short damp nose, large plate eyes, and ears which hardly stand out from the skin. It typically has a strictly vegetarian diet of leaves and buds, living together in small families. The local population calls the species ''dadintsifaky'', which means "Grandfather of the si ...

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] |
Sifaka
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 skillf ...

Betsileo Woolly Lemur
The Betsileo woolly lemur or Betsileo avahi (''Avahi betsileo'') is a species of woolly lemur native to southeastern Madagascar, in the District of Fandriana. The pelage differs significantly from other southeastern woolly lemurs in that it is primarily light reddish brown on most of the body and grey under the jaw and on the extremities. The pelage is thicker on the head than other eastern woolly lemurs. This lemur is an arboreal, herbivorous, nocturnal, female dominant nonhuman primate, with a body length of about , including a 28.3-34.4 cm (11.14-13.54 in) tail, it is weighing about . ''Avahi betsileo'' prefers to inhabit humid rainforests, are vertical clingers and leapers. Distribution The Betsileo woolly lemur can be found in the Bemosary classified forest, Madagascar. Conservation According to the IUCN, ''Avahi betsileo'' is classified as Endangered species.

Ramanantsoavana's Woolly Lemur
Ramanantsoavana's woolly lemur (''Avahi ramanantsoavanai''), also known as Ramanantsoavana's avahi or the Manombo woolly lemur, is a species of woolly lemur native to southeastern Madagascar. It weighs about 1 kg. It was originally considered a subspecies of the southern woolly lemur The southern woolly lemur (''Avahi meridionalis''), or southern avahi, has been recently recognized as a separate species of woolly lemur in 2006 by Zaramody ''et al.'' It is a nocturnal and pair-living species. Groups can range from 2 (the paren ...

Southern Woolly Lemur
The southern woolly lemur (''Avahi meridionalis''), or southern avahi, has been recently recognized as a separate species of woolly lemur in 2006 by Zaramody ''et al.'' It is a nocturnal and pair-living species. Groups can range from 2 (the parental pair only) to 5 individuals (including the offspring of subsequent years). A study in Sainte Luce forest revealed home range varied from 2.2 to 3.5 ha and that males can have larger home range and cover longer daily distances than females (which can spend more time feeding), in agreement with the territory defence and mate guarding hypotheses. Distribution The species is restricted to the reserve of Andohahela and the area of Sainte Luce. Further studies are required to determine the exact distribution range and especially the limits with its sister species Peyrieras' woolly lemur (''A. peyrierasi''). In southeastern littoral forests, sympatric lemur species of ''Avahi meridionalis'' are the brown mouse lemur (''Microcebus rufus''), th ...
