Giraffe
The giraffe is a large Fauna of Africa, African even-toed ungulate, hoofed mammal belonging to the genus ''Giraffa.'' It is the Largest mammals#Even-toed Ungulates (Artiodactyla), tallest living terrestrial animal and the largest ruminant on Earth. It is classified under the Family (biology), family Giraffidae, along with its closest extant relative, the okapi. Traditionally, giraffes have been thought of as one species, ''Giraffa camelopardalis'', with nine subspecies. Most recently, researchers proposed dividing them into four Neontology#Extant taxa versus extinct taxa, extant species which can be distinguished by their fur Animal coat, coat patterns. Six valid Lists of extinct species, extinct species of ''Giraffa'' are known from the fossil record. The giraffe's distinguishing characteristics are its extremely long neck and legs, horn-like ossicones, and spotted coat patterns. Its scattered range extends from Chad in the north to South Africa in the south and from Niger in ... [...More Info...] [...Related Items...] OR: [Wikipedia] [Google] [Baidu] |
Giraffidae
The Giraffidae are a family (biology), family of ruminant artiodactyl mammals that share a recent common ancestor with deer and bovids. This family, once a diverse group spread throughout Eurasia and Africa, presently comprises only two extant genera, the giraffe (between one and eight, usually four, species of ''Giraffa'', depending on taxonomic interpretation) and the okapi (the only known species of ''Okapia''). Both are confined to sub-Saharan Africa: the giraffe to the open savannas, and the okapi to the dense rainforest of the Democratic Republic of the Congo, Congo. The two genera look very different on first sight, but share a number of common features, including a long, dark-coloured tongue, lobed canine teeth, and horns covered in skin, called ossicones. Taxonomy Evolutionary background The giraffids are ruminants of the clade Pecora. Other extant pecorans are the families Antilocapridae (pronghorns), Cervidae (deer), Moschidae (musk deer), and Bovidae (Bovini, cattl ...

Masai Giraffe
The Masai giraffe (''Giraffa tippelskirchi''), also spelled Maasai giraffe, and sometimes called the Kilimanjaro giraffe, is a species or subspecies of giraffe. It is native to East Africa. The Masai giraffe can be found in central and southern Kenya and in Tanzania and Uganda. It has distinctive jagged, irregular leaf-like blotches that extend from the hooves to its head. The Masai giraffe is currently the national animal of Tanzania. Taxonomy The IUCN currently recognizes only one species of giraffe with nine subspecies The Masai giraffe was described and given the binomial name ''Giraffa tippelskirchi'' by German zoologist Paul Matschie in 1898, but current taxonomy refers to Masai giraffe as ''Giraffa camelopardalis tippelskirchi''. The Masai giraffe was named in honor of Herr von Tippelskirch, who was a member of a German scientific expedition in German East Africa to what is now northern Tanzania in 1896. Tippelskirch brought back the skin of a female Masai giraffe from ne ... [...More Info...] [...Related Items...] OR: [Wikipedia] [Google] [Baidu] |
Giraffa Camelopardalis
The northern giraffe (''Giraffa camelopardalis''), also known as three-horned giraffe, is the type species of giraffe, ''G. camelopardalis'', and is native to North Africa, although alternative taxonomic hypotheses have proposed the northern giraffe as a separate species. Once abundant throughout Africa since the 19th century, the northern giraffe ranged from Senegal, Mali and Nigeria from West Africa to up north in Egypt. The similar West African giraffe lived in Algeria and Morocco in ancient periods until their extinctions due to the Saharan dry climate. Giraffes collectively are listed as Vulnerable on the IUCN Red List, as the global population is thought to consist of about 97,000 individuals as of 2016. Taxonomy and evolution The current IUCN taxonomic scheme lists one species of giraffe with the name ''G. camelopardalis'' and nine subspecies. A 2021 whole genome sequencing study suggests the northern giraffe as a separate species, and postulates the existence of thre ...

Okapi
The okapi (; ''Okapia johnstoni''), also known as the forest giraffe, Congolese giraffe and zebra giraffe, is an artiodactyl mammal that is endemic to the northeast Democratic Republic of the Congo in central Africa. However, non-invasive genetic identification has suggested that a population has occurred south-west of the Congo River as well. It is the only species in the genus ''Okapia''. Although the okapi has striped markings reminiscent of zebras, it is most closely related to the giraffe. The okapi and the giraffe are the only living members of the family Giraffidae. The okapi stands about tall at the shoulder and has a typical body length around . Its weight ranges from . It has a long neck, and large, flexible ears. Its coat is a chocolate to reddish brown, much in contrast with the white horizontal stripes and rings on the legs, and white ankles. Male okapis have short, distinct horn-like protuberances on their heads called ossicones, less than in length. Female ... [...More Info...] [...Related Items...] OR: [Wikipedia] [Google] [Baidu] |
Ossicone
Ossicones are columnar or conical skin-covered bone structures on the heads of giraffes, male okapi, and some of their extinct relatives. Ossicones are distinguished from the superficially similar structures of Horn (anatomy), horns and antlers by their unique development and a permanent covering of skin and fur. Structure Giraffe ossicones consist of a highly vascularized and innervated bone core covered with similarly vascularized and innervated skin. They are attached to the skull with vascularized, innervated connective tissue. Ossicones are formed at late gestation, but in early development they are not bony and not fused to the skull yet. Ossicones usually fuse to the skull at sexual maturity. All male and female giraffes have a pair of parietal ossicones on the parietal bones of the skull. Males also usually have a single median ossicone on the frontal bone that is larger in northern animals and smaller in southern giraffes. Giraffes can also have small additional paire ...

Even-toed Ungulate
Artiodactyls are placental mammals belonging to the order Artiodactyla ( , ). Typically, they are ungulates which bear weight equally on two (an even number) of their five toes (the third and fourth, often in the form of a hoof). The other three toes are either present, absent, vestigial, or pointing posteriorly. By contrast, most perissodactyls bear weight on an odd number of the five toes. Another difference between the two orders is that many artiodactyls (except for Suina) digest plant cellulose in one or more stomach chambers rather than in their intestine (as perissodactyls do). Molecular biology, along with new fossil discoveries, has found that cetaceans (whales, dolphins, and porpoises) fall within this taxonomic branch, being most closely related to hippopotamuses. Some modern taxonomists thus apply the name Cetartiodactyla () to this group, while others opt to include cetaceans within the existing name of Artiodactyla. Some researchers use "even-toed ungulates" to e ... [...More Info...] [...Related Items...] OR: [Wikipedia] [Google] [Baidu] |
Mikumi National Park
Mikumi National Park is a national park in Tanzania located near the city of Morogoro, with an area of that was established in 1964. It is the fourth largest in the country. Territory Mikumi National Park borders Selous Game Reserve on the south, the two areas forming a unique ecosystem. Two other natural areas bordering the national park are the Udzungwa Mountains and Uluguru Mountains. Malundwe Mountain is within the park, the highest of a belt of hills that run east and west through the park, connecting the Uluguru Mountains to the northeast with the Uvidunda Mountains, Uvidunda and Udzungwa mountains to the west. Malundwe Mountain consists of three peaks along a ridge running north and south. Malundwe's south peak is the highest point in the park, reaching 1290 meters elevation. Flora and fauna The landscape of Mikumi is often compared to that of the Serengeti. The road that crosses the park divides it into two areas with partially distinct environments. The area north-we ... [...More Info...] [...Related Items...] OR: [Wikipedia] [Google] [Baidu] |
Tanzania
Tanzania, officially the United Republic of Tanzania, is a country in East Africa within the African Great Lakes region. It is bordered by Uganda to the northwest; Kenya to the northeast; the Indian Ocean to the east; Mozambique and Malawi to the south; Zambia to the southwest; and Rwanda, Burundi, and the Democratic Republic of the Congo to the west. According to a 2024 estimate, Tanzania has a population of around 67.5 million, making it the most populous country located entirely south of the equator. Many important hominid fossils have been found in Tanzania. In the Stone and Bronze Age, prehistoric migrations into Tanzania included South Cushitic languages, Southern Cushitic speakers similar to modern day Iraqw people who moved south from present-day Ethiopia; Eastern Cushitic people who moved into Tanzania from north of Lake Turkana about 2,000 and 4,000 years ago; and the Southern Nilotic languages, Southern Nilotes, including the Datooga people, Datoog, who originated fro ...

Fauna Of Africa
The fauna of Africa are all the animals living in Africa and its surrounding seas and islands. The more characteristic African fauna are found in the Afrotropical realm, Afro-tropical realm. Lying almost entirely within the tropics, and stretching equally north and south of the equator creates favorable conditions for variety and abundance of wildlife. Africa is home to many of the world's most recognizable fauna such as lions‚ rhinoceroses‚ cheetahs‚ giraffes‚ antelope, hippopotamuses, leopards, zebras‚ and African elephant, elephants, among many others. Origins and history of African fauna Whereas the earliest traces of life in fossil record of Africa date back to the earliest times, the formation of African fauna as we know it today, began with the splitting up of the Gondwana supercontinent in the mid-Mesozoic era. After that, four to six faunal assemblages, the so-called African Faunal Strata (AFSs) can be distinguished. The isolation of Africa was broken intermitte ...

Ruminant
Ruminants are herbivorous grazing or browsing artiodactyls belonging to the suborder Ruminantia that are able to acquire nutrients from plant-based food by fermenting it in a specialized stomach prior to digestion, principally through microbial actions. The process, which takes place in the front part of the digestive system and therefore is called foregut fermentation, typically requires the fermented ingesta (known as cud) to be regurgitated and chewed again. The process of rechewing the cud to further break down plant matter and stimulate digestion is called rumination. The word "ruminant" comes from the Latin ''ruminare'', which means "to chew over again". The roughly 200 species of ruminants include both domestic and wild species. Ruminating mammals include cattle, all domesticated and wild bovines, goats, sheep, giraffes, deer, gazelles, and antelopes.Fowler, M.E.
