Ankarana Massif
Ankarana Special Reserve in northern Madagascar was created in 1956. It is a small, partially vegetated plateau composed of 150-million-year-old middle Jurassic limestone. With an average annual rainfall of about , the underlying rocks have been eroded to produce caves and feed subterranean rivers—a karst topography. The rugged relief and the dense vegetation have helped protect the region from human intrusion. The southern entrance of the park is in Mahamasina on the Route nationale 6 some 108 km south-west of Antsiranana and north-east of Ambilobe. Geology The plateau slopes gently to the east, but on the west it ends abruptly in the "Wall of Ankarana", a sheer cliff that extends north to south, and rises up to . To the south, the limestone mass breaks up into separate spires known as ''tower karst''. In the center of the plateau, seismic activity and eons of rainfall have eroded the limestone, forming deep gorges and ribbons of flowstone. In places where the cal ...

Madagascar
Madagascar (; mg, Madagasikara, ), officially the Republic of Madagascar ( mg, Repoblikan'i Madagasikara, links=no, ; french: République de Madagascar), is an island country in the Indian Ocean, approximately off the coast of East Africa across the Mozambique Channel. At Madagascar is the world's List of island countries, second-largest island country, after Indonesia. The nation is home to around 30 million inhabitants and consists of the island of Geography of Madagascar, Madagascar (the List of islands by area, fourth-largest island in the world), along with numerous smaller peripheral islands. Following the prehistoric breakup of the supercontinent Gondwana, Madagascar split from the Indian subcontinent around 90 million years ago, allowing native plants and animals to evolve in relative isolation. Consequently, Madagascar is a biodiversity hotspot; over 90% of wildlife of Madagascar, its wildlife is endemic. Human settlement of Madagascar occurred during or befo ...

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 ...

Eastern Woolly Lemur
The eastern woolly lemur (''Avahi laniger''), 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 and reaches a length of with a tail of . Its diet consists mainly of leaves and buds with fruits, flowers, and bark. Eastern woolly lemurs live in monogamous pairs together with their offspring. The eastern woolly lemur's breeding season ranges from March to May with the baby lemurs being born around August to September. Other lemur species that live in ...

Fork-marked Lemur
Fork-marked lemurs or fork-crowned lemurs are strepsirrhine primates; the four species comprise the genus ''Phaner''. Like all lemurs, they are native to Madagascar, where they are found only in the west, north, and east sides of the island. They are named for the two black stripes which run up from the eyes, converge on the top of the head, and run down the back as a single black stripe. They were originally placed in the genus ''Lemur'' in 1839, later moved between the genera '' Cheirogaleus'' and ''Microcebus'', and given their own genus in 1870 by John Edward Gray. Only one species ('' Phaner furcifer'') was recognized, until three subspecies described in 1991 were promoted to species status in 2001. New species may yet be identified, particularly in northeast Madagascar. Fork-marked lemurs are among the least studied of all lemurs and are some of the largest members of the family Cheirogaleidae, weighing around or more. They are the most phylogenetically distinct of the ch ...

Fat-tailed Dwarf Lemur
The fat-tailed dwarf lemur (''Cheirogaleus medius''), also known as the lesser dwarf lemur, western fat-tailed dwarf lemur, or spiny forest dwarf lemur, is endemic to Madagascar. Hibernation Recent research has shown that ''C. medius'' hibernates (or aestivates), even though in the tropical winter of Madagascar, temperatures remain high. It is the first tropical mammal and only primate in which hibernation has been demonstrated. However, the Malagasy winter is dry, and it appears that the lemur is avoiding the drought. It can hibernate for seven months. Unlike animals that hibernate in temperate regions, the lemur does not control its body temperature while hibernating, and if the tree hole in which it is sleeping is not well insulated, its body temperature fluctuates in accordance with the outside temperature. During torpor, this lemur has been found to periodically enter REM sleep; non-REM sleep has not been observed, a pattern opposite that found in hibernating ground squirre ...

Brown Mouse Lemur
The brown mouse lemur (''Microcebus rufus'') is a small primate, and like the other mouse lemurs can only be found on the island of Madagascar. They are known also as the rufous mouse lemur, eastern rufous mouse lemur, red mouse lemur, or russet mouse lemur. Its dorsal side is brown or reddish-brown, while ventrally it is a whitish-grey. It was originally considered a subspecies of the gray mouse lemur (''Microcebus murinus'') until 1977, when it was reclassified as a separate species. The mouse lemurs are among the shortest-lived of primates. The brown mouse lemur has a lifespan of 6–8 years in the wild, although it averages 12 years under human care. It can be found in rainforests in Eastern Madagascar, and is widely distributed. It is a solitary and nocturnal creature. Brown mouse lemurs are mammals.

Northern Sportive Lemur
The northern sportive lemur (''Lepilemur septentrionalis''), also known as the Sahafary sportive lemur or northern weasel lemur, is a species of lemur in the family Lepilemuridae. It is endemic to Madagascar. As a result of severe ecological and human pressures, the lemur is classified as Critically Endangered (CR) by the IUCN Red List. Taxonomy The genus ''Lepilemur'' was initially thought to comprise only 2 species: ''L. mustelinus'' and ''L. ruficaudatus'', with the latter subdivided into 2 subspecies. The genus was later reclassified as having only 1 species, ''mustelinus'', with 5 subspecies. In 1977, Petter et al. increased the species number of the genus to 7, at which point the species ''L. septentrionalis'' was demarcated, and classified as having 4 subspecies. As 2 of these subspecies were not geographically distinct, the number of ''L. septentrionalis'' subspecies was eventually condensed to 2: ''L. s. septentrionalis'' and ''L. s. ankaranensis''. As a result of ...

Crowned Lemur
The crowned lemur (''Eulemur coronatus'') is a lemur that is long and weighs . Its tail is about long. Description The crowned lemur is endemic to the dry deciduous forests of the northern tip of Madagascar. It eats a diet of mostly flowers, fruits, and leaves. The population is estimated to 1000–10,000 individuals as of 2004, most of which live within the Ankarana Plateau, although there is also a population on the Montagne d'Ambre. This species has a distinctive brown-orange crown on the top of the head. Females have a gray body with an orange crown, and males are a darker reddish brown, crowned with black and orange. Crowned lemurs have a life span of approximately 20 years and reach sexual maturity after 20 months. They give birth usually in late September or early October, after a gestation period of 125 days. The crowned lemur is in the order of Primates as it possesses characteristics such as pseudo-opposable thumbs, binocular vision and is highly intelligent. ''E. cor ...
