Galago (Otolicnus Galago)
Galagos , also known as bush babies, or ''nagapies'' (meaning "night monkeys" in Afrikaans), are small nocturnal primates native to continental, sub-Sahara Africa, and make up the family Galagidae (also sometimes called Galagonidae). They are considered a sister group of the Lorisidae. According to some accounts, the name "bush baby" comes from either the animal's cries or its appearance. The Ghanaian name ''aposor'' is given to them because of their firm grip on branches. In both variety and abundance, the bush babies are the most successful strepsirrhine primates in Africa, according to the African Wildlife Foundation. Taxonomic classification and phylogeny Galagos are currently grouped into six genera. ''Euoticus'' is a basal sister taxon to all the other galagids. The 'dwarf' galagids recently grouped under the genus ''Galagoides'' have been found, based on genetic data, and supported by analysis of vocalisations and morphology, to actually consist of two clades, w ...

Brown Greater Galago
The brown greater galago (''Otolemur crassicaudatus''), also known as the large-eared greater galago or thick-tailed galago, is a nocturnal animal, nocturnal primate, the largest in the family of galagos. As opposed to smaller galago species it would climb, walk or run rather than leap. Taxonomy Two subspecies of ''Otolemur crassicaudatus'' are recognised: *''O. c. crassicaudatus'' *''O. c. kirkii'' The IUCN considers the silvery greater galago as a third subspecies, ''O. c. monteiri''. Other sources treat it as a separate species, though with "misgivings". The IUCN Red List assesses all three forms individually as Least Concern. Physical characteristics This species has a rounded head with a short, wide snout, very large ears that can be moved independently and relatively large forward binocular eyes. They possess flat thickened skin pads at the ends of their fingers and toes for grasping limbs. The fingers are long and toes are flattened with flattened nails. The dentiti ...

Dusky Bushbaby
The dusky bushbaby (''Galago matschiei'') is a species of primate in the family Galagidae. It is also known as Matschie's galago, in honour of the German zoologist Paul Matschie, curator of mammals at the Museum für Naturkunde in Berlin. Native to tropical Central Africa, it is found in forests in Burundi, Rwanda, Democratic Republic of the Congo and Uganda. The species is small with a long tail, and has an arboreal, nocturnal and omnivorous lifestyle. Description The dusky bushbaby is a medium-sized galago with a head-and-body length of approximately and a tail of . It weighs around . The face is distinctively marked with a broad pale streak extending from the snout to the fore-head. The large eyes have amber-coloured irises and are surrounded by brownish-black eye rings, outside which is a ridge, particularly obvious on the fore-head. The cheeks are pale grey and the long ears are either black or tipped with black. The upper parts of the body and limbs are dark brown, with a y ...

Senegal Bushbaby
The Senegal bushbaby (''Galago senegalensis''), also known as the Senegal galago, the lesser galago or the lesser bush baby, is a small, nocturnal primate, a member of the galago family Galagidae. The name "bush baby" may come either from the animals' cries or from their appearance. They are agile leapers, and run swiftly along branches. They live in Africa south of the Sahara and nearby islands including Zanzibar. They tend to live in dry woodland regions and savannah regions. They are small primates (130 mm and 95 - 300 grams) with woolly thick fur that ranges from silvery grey to dark brown. They have large eyes, giving them good night vision; strong hind limbs; and long tails, which help them balance. Their ears are made up of four segments that can bend back individually, to aid their hearing when hunting insects at night. Their omnivorous diet is a mixture of other small animals, including birds and insects, fruit, seeds, flowers, eggs, nuts, and tree gums. Bushbabies ...

Mohol Bushbaby
The Mohol bushbaby (''Galago moholi'') is a species of primate in the family Galagidae which is native to mesic woodlands of the southern Afrotropics. It is physically very similar to the Senegal bushbaby, and was formerly considered to be its southern race. The two species differ markedly in their biology however, and no hybrids have been recorded in captivity. Description The Mohol bushbaby is a medium size species with a head-and-body length of and a tail of .The head is broad, with a short muzzle, orange eyes and diamond-shaped black eye-rings. The nose-stripe is whitish and the ears are large and grey. The dorsal surface of the body has a greyish-brown pelage, and the underparts are white, sometimes with a yellowish tinge. The flanks, inside of the limbs, hands and feet are yellowish. The fingers and toes have spatulate tips. The tail is darker than the rest of the fur but is not very bushy. Range It is found in Angola, Botswana, Democratic Republic of the Congo, Malawi, M ... [...More Info...] [...Related Items...] OR: [Wikipedia] [Google] [Baidu] |
Somali Bushbaby
The Somali bushbaby (''Galago gallarum''), or the Somali lesser galago, as it is also known, is a species of nocturnal, arboreal primate in the family Galagidae. It is found in Ethiopia, Kenya, and Somalia. It is threatened by habitat loss. Distribution The Somali Bushbaby is found in Kenya, Somalia and Ethiopia. Unlike other galagos, it is endemic to the thorny woodland/scrub and semi-arid thorn scrub which covers large tracts of south-western Ethiopia, Kenya (except for the coastal strip, semi-desert region east of Lake Turkana, and area east of Lake Victoria), and in Somalia from Odweina near the Red sea southward to the border with Kenya. Taxonomy First described by Oldfield Thomas in 1901, it was later classified as one of the many subspecies of the Senegal lesser galago ''Galago senegalensis''. T.R. Olson, in his Ph.D. thesis in 1979, and his paper of 1986, raised it once again to the status of a separate species, which reclassification has not been disputed by other acad ...

Northern Needle-clawed Bushbaby
The northern needle-clawed bushbaby (''Euoticus pallidus'') is a species of strepsirrhine primate in the family Galagidae. It is found in the coastal region of Cameroon and Nigeria, and on the island of Bioko, Equatorial Guinea in lower-elevation forests that provide its specialized diet of tree gum and resins. Description This is a medium-sized species with a head-and-body length of and a tail of . Members of this genus have long limbs and large hands and feet. The fur is woolly and they have short, blunt snouts, large orange eyes and bony ridges surrounding the eyes. The nails on both hands and feet are keeled, and are elongated forward into sharp points. These nails are an adaptation to help provide grip on large branches of trees. The upper parts of this bushbaby, and the outer parts of the limbs, are reddish-grey or reddish-buff, being greyer on the neck, shoulders, arms and tail. Some individuals have a dark greyish-brown dorsal stripe running from the shoulders to the root ... [...More Info...] [...Related Items...] OR: [Wikipedia] [Google] [Baidu] |
Southern Needle-clawed Bushbaby
The southern needle-clawed bushbaby (''Euoticus elegantulus'') is a species of strepsirrhine primate in the family Galagidae. Found in Cameroon, Central African Republic, Republic of the Congo, and possibly Democratic Republic of the Congo, its natural habitat is tropical moist forests. While the species is not threatened or endangered, some local populations may be threatened by habitat destruction. Description This species is medium-sized, with a head-and-body length of and a tail of . The sexes are similar in appearance, but there is considerable geographical variation in this species; animals from near the coast are larger and paler than those from inland. The upper parts of the body are bright orange, often darker on the shoulders, contrasting with the silvery-grey of the underparts and inner sides of the limbs. The tip of the tail is whitish in many individuals. In common with the northern needle-clawed bushbaby (''Euoticus pallidus''), the nails have strong ridges and end ...

East African Rift
The East African Rift (EAR) or East African Rift System (EARS) is an active continental rift zone in East Africa. The EAR began developing around the onset of the Miocene, 22–25 million years ago. In the past it was considered to be part of a larger Great Rift Valley that extended north to Asia Minor. A narrow zone, the rift is a developing divergent tectonic plate boundary where the African Plate is in the process of splitting into two tectonic plates, called the Somali Plate and the Nubian Plate, at a rate of 6-7 mm per year. The rift system consists of three microplates, the Victoria Microplate to the north, and the Rovuma and Lwandle microplates to the south. The Victoria Microplate is rotating anti-clockwise with respect to the African plate. Its rotation is caused by the configuration of mechanically weaker and stronger lithospheric regions in the EARS. Extent A series of distinct rift basins, the East African Rift System extends over thousands of kilometers. The ... [...More Info...] [...Related Items...] OR: [Wikipedia] [Google] [Baidu] |
Sister Taxon
In phylogenetics, a sister group or sister taxon, also called an adelphotaxon, comprises the closest relative(s) of another given unit in an evolutionary tree. Definition The expression is most easily illustrated by a cladogram: Taxon A and taxon B are sister groups to each other. Taxa A and B, together with any other extant or extinct descendants of their most recent common ancestor (MRCA), form a monophyletic group, the clade AB. Clade AB and taxon C are also sister groups. Taxa A, B, and C, together with all other descendants of their MRCA form the clade ABC. The whole clade ABC is itself a subtree of a larger tree which offers yet more sister group relationships, both among the leaves and among larger, more deeply rooted clades. The tree structure shown connects through its root to the rest of the universal tree of life. In cladistic standards, taxa A, B, and C may represent specimens, species, genera, or any other taxonomic units. If A and B are at the same taxonomi ...
