The Indriidae 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.
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.
Verreaux's sifaka, or the white sifaka, is a medium-sized primate in one of the lemur families, the Indriidae. It lives in Madagascar and can be found in a variety of habitats from rainforest to dry deciduous forests of western Madagascar and the spiny thickets of the south. Its fur is thick and silky and generally white with brown on the sides, top of the head, and on the arms. Like all sifakas, it has a long tail that it uses as a balance when leaping from tree to tree. However, its body is so highly adapted to an arboreal existence, on the ground its only means of locomotion is hopping. The species lives in small troops which forage for food.
The eastern woolly lemur, also known as the eastern avahi or Gmelin's woolly lemur, is a species of woolly lemur native to eastern Madagascar, where it lives in the wet tropical rainforest at low elevations along the eastern coast of the island or they can also inhabit the northern tip of the island with other species. The woolly lemur name refers to their thick, tightly curled hair, whereas their generic name avahi refers to their high-pitched defensive call. The eastern woolly lemur almost has an owl-look with its large eyes, small rounded head, and ears that are mostly hidden. This nocturnal animal weighs 1.0–1.3 kg (2.2–2.9 lb) and reaches a length of 27–29 cm (11–11 in) with a tail of 33–37 cm (13–15 in). Its diet consists mainly of leaves and buds with fruits, flowers, and bark.
Baron Karl Klausvon der Decken was a German explorer of eastern Africa and the first European to attempt to climb Mount Kilimanjaro.
The diademed sifaka, 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.
Coquerel's sifaka is a diurnal, medium-sized lemur of the sifaka genus Propithecus. It is native to northwest Madagascar. Coquerel's sifaka was once considered to be a subspecies of Verreaux's sifaka, but was eventually granted full species level, and is listed as Critically Endangered on the IUCN Red List due to habitat loss and hunting. In popular culture, it is known for being the species of the title character in the children's TV show Zoboomafoo. The species was named after French entomologist Charles Coquerel.
The golden-crowned sifaka or Tattersall's sifaka 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, weighing around 3.5 kg (7.7 lb) and measuring approximately 90 cm (35 in) 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 classification as a distinct species.
Decken's horseshoe bat is a species of horseshoe bat. It is found in Kenya and Tanzania. Its natural habitats are tropica and subtropical moist lowland and montane forest, moist savanna, caves and other subterranean habitats.
The silky sifaka 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, 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.
Namoroka National Park, formerly known as Tsingy de Namoroka Strict Nature Reserve, is a national park located in the northwestern part of Madagascar in the Mahajanga Province, specifically, the Soalala District.
Andranomena Special Reserve is a wildlife reserve in Menabe Region, western Madagascar, near the city of Morondava and the rural commune of Bemanonga.
Ambatovaky Special Reserve is a tropical rainforest and wildlife reserve in the north-east of Madagascar. It is designated by Bird Life International as an Important Bird Area for the large number of endemic species of birds.
Ambohijanahary Special Reserve is a wildlife reserve in the regions of Menabe and Melaky in Madagascar. The reserve was created in 1958 to protect the sclerophyllous forest between Tsiroanomandidy and Maintirano, as well as protecting the many endemic species of plants and animals.
Perrier's sifaka 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 90 cm (35 in), half of which is a bushy tail. Females are slightly larger than males.
The crowned sifaka is a sifaka endemic to western Madagascar, a part of the world where nature and its biological diversity faces enormous and devastating consequences resulting from anthropogenic activities. It is a species of lemur belonging to the Idriidae family, it is of comparable size to the Golden-crowned sifaka and up to a meter in length, of which 47-57 centimeters are tail. The species is an arboreal vertical climber and leaper whose diet consists of leaves, fruits and flowers. It is threatened by habitat destruction caused by human activities and is currently classified as critically endangered by the IUCN. Conservation planning needs to take local people needs and views into account in order to be successful over the long term.
Milne-Edwards's sifaka, 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.
