Crawshay's Zebra
Crawshay's zebra (''Equus quagga crawshayi'') is a subspecies of the plains zebra native to eastern Zambia, east of the Luangwa River, Malawi, southeastern Tanzania, and northern Mozambique Mozambique, officially the Republic of Mozambique, is a country located in Southeast Africa bordered by the Indian Ocean to the east, Tanzania to the north, Malawi and Zambia to the northwest, Zimbabwe to the west, and Eswatini and South Afr ... south to the Gorongoza District. Crawshay's zebras can be distinguished from other subspecies of plains zebras in that its lower incisors lack an infundibulum. Crawshay's zebra has very narrow stripes compared to other forms of the plains zebra.

South Luangwa National Park
South Luangwa National Park is a national park in eastern Zambia that was founded as a game reserve in 1938 and became a national park in 1972. It covers in the valley of the Luangwa River, which forms its eastern boundary in the Eastern Province of Zambia. It is bordered to the west by a steep escarpment, the Muchinga Escarpment in Muchinga and Central Provinces. The Luangwa Valley lies at the end of the East African Rift valley. The meandering Luangwa River and its lagoons support over 400 bird species and more than 60 mammal species including Rhodesian giraffe, African bush elephant and African buffalo. History South Luangwa National Park was initially created as Luangwa Game Reserve in 1904. British conservationist Norman Carr was influential in setting up the South Luangwa National Park. A man ahead of his time, Norman Carr broke the mould of track-and-hunt safari and created conservation based tourism. In the 1950s, a portion of tribal land was set aside as a game r ...

Zambia
Zambia, officially the Republic of Zambia, is a landlocked country at the crossroads of Central Africa, Central, Southern Africa, Southern and East Africa. It is typically referred to being in South-Central Africa or Southern Africa. It is bordered to the north by the Democratic Republic of the Congo, Tanzania to the north-east, Malawi to the east, Mozambique to the southeast, Zimbabwe and Botswana to the south, Namibia to the southwest, and Angola to the west. The capital city of Zambia is Lusaka, located in the south-central part of Zambia. The population is concentrated mainly around Lusaka in the south and the Copperbelt Province to the north, the core economic hubs of the country. Originally inhabited by Khoisan peoples, the region was affected by the Bantu expansion of the thirteenth century. Following European colonization of Africa, European colonisers in the 18th century, the British colonised the region into the British protectorates of Barotziland–North-Western Rho ...

Subspecies
In Taxonomy (biology), biological classification, subspecies (: subspecies) is a rank below species, used for populations that live in different areas and vary in size, shape, or other physical characteristics (Morphology (biology), morphology), but that can successfully interbreed. Not all species have subspecies, but for those that do there must be at least two. Subspecies is abbreviated as subsp. or ssp. and the singular and plural forms are the same ("the subspecies is" or "the subspecies are"). In zoology, under the International Code of Zoological Nomenclature, the subspecies is the only taxonomic rank below that of species that can receive a name. In botany and mycology, under the International Code of Nomenclature for algae, fungi, and plants, other infraspecific name, infraspecific ranks, such as variety (botany), variety, may be named. In bacteriology and virology, under standard International Code of Nomenclature of Prokaryotes, bacterial nomenclature and virus clas ...

Plains Zebra
The plains zebra (''Equus quagga'', formerly ''Equus burchellii'') is the most common and geographically widespread species of zebra. Its range is fragmented, but spans much of southern and eastern Africa south of the Sahara. Six or seven subspecies have been recognised, including the quagga which was thought to be a separate species. More recent research supports variations in zebra populations being Cline (biology), clines rather than subspecies. Plains zebras are intermediate in size between the larger Grévy's zebra and the smaller mountain zebra and tend to have broader stripes than both. Great variation in coat patterns exists between clines and individuals. The plains zebra's habitat is generally, but not exclusively, treeless grasslands and savanna woodlands, both tropical and temperate. They generally avoid desert, dense rainforest and permanent wetlands. Zebras are preyed upon by lions and spotted hyenas, Nile crocodiles and, to a lesser extent, African leopard, leopards ...

Luangwa River
The Luangwa River is one of the major Tributary, tributaries of the Zambezi River, and one of the four biggest rivers of Zambia. The river generally floods in the rainy season (December to March) and then falls considerably in the dry season. It is one of the biggest unaltered rivers in Southern Africa and the that make up the surrounding valley are home to abundant wildlife. Source and upper-middle course ''Note: distances stated are approximate straight-line distances from source''. The Luangwa rises in the Lilonda and Mafinga Hills in north-east Zambia at an elevation of around , near the border with Tanzania and Malawi, and flows in a southwesterly direction through a broad valley. About from its source it has dropped to an elevation of about and becomes a meandering river with a floodplain several kilometres wide. Over the next the meanders increase, with many oxbow lakes and Meander#Abandoned meander, abandoned meanders. Near Mfuwe, the river's elevation has dropped ...

Malawi
Malawi, officially the Republic of Malawi, is a landlocked country in Southeastern Africa. It is bordered by Zambia to the west, Tanzania to the north and northeast, and Mozambique to the east, south, and southwest. Malawi spans over and has an estimated population of 21,240,689 (as of 2024). Lilongwe is its capital and largest city, while the next three largest cities are Blantyre, Mzuzu, and Zomba, the former capital. The part of Africa now known as Malawi was settled around the 10th century by the Akafula, also known as the Abathwa. Later, the Bantu groups came and drove out the Akafula and formed various kingdoms such as the Maravi and Nkhamanga kingdoms, among others that flourished from the 16th century. In 1891, the area was colonised by the British as the British Central African Protectorate, and it was renamed '' Nyasaland'' in 1907. In 1964, Nyasaland became an independent country as a Commonwealth realm under Prime Minister Hastings Banda, and was rena ...

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 ...

Mozambique
Mozambique, officially the Republic of Mozambique, is a country located in Southeast Africa bordered by the Indian Ocean to the east, Tanzania to the north, Malawi and Zambia to the northwest, Zimbabwe to the west, and Eswatini and South Africa to the south and southwest. The sovereign state is separated from the Comoros, Mayotte, and Madagascar by the Mozambique Channel to the east. The capital and largest city is Maputo. Between the 7th and 11th centuries, a series of Swahili port towns developed on that area, which contributed to the development of a distinct Swahili culture and dialect. In the late medieval period, these towns were frequented by traders from Somalia, Ethiopia, Egypt, Arabia, Persia, and India. The voyage of Vasco da Gama in 1498 marked the arrival of the Portuguese Empire, Portuguese, who began a gradual process of colonisation and settlement in 1505. After over four centuries of Portuguese Mozambique, Portuguese rule, Mozambique Mozambican War of Indepen ... [...More Info...] [...Related Items...] OR: [Wikipedia] [Google] [Baidu] |

Incisor
Incisors (from Latin ''incidere'', "to cut") are the front teeth present in most mammals. They are located in the premaxilla above and on the mandible below. Humans have a total of eight (two on each side, top and bottom). Opossums have 18, whereas armadillos, anteaters and other animals in the order Edentata have none. Structure Adult humans normally have eight incisors, two of each type. The types of incisors are: * maxillary central incisor (upper jaw, closest to the center of the lips) * maxillary lateral incisor (upper jaw, beside the maxillary central incisor) * mandibular central incisor (lower jaw, closest to the center of the lips) * mandibular lateral incisor (lower jaw, beside the mandibular central incisor) Children with a full set of deciduous teeth (primary teeth) also have eight incisors, named the same way as in permanent teeth. Young children may have from zero to eight incisors depending on the stage of their tooth eruption and tooth development. Typic ...

Infundibulum (tooth)
The infundibulum of a tooth is the funnel-like center that is filled with ''cementum''. The funnel is widest at the top (crown) which is the grinding (occlusal) surface. The infundibulum is also known as the ''dental cup''. Simple tooth infundibula occur most notably in the incisors of horses and other equids, but they also occur in the premolars and molars of ruminants and camelids. The infundibula found in ruminants can get quite complex some with two funneling centers, and with multiple folding in the sides of the cup. These folds produce greater amounts of enamel in vertical curtains that substantially increase the durability of the tooth. The cheek teeth of elephants express this in a slightly different form with the vertical curtains of enamel coming in from the sides and meeting in the middle. In horses and most equines the cross section of the tooth at the grinding (occlusal) surface shows the roughly circular or ovoid infundibulum as the incisor begins to wear. When the ...

Zebras
Zebras (, ) (subgenus ''Hippotigris'') are African equines with distinctive black-and-white striped Animal coat, coats. There are three Extant taxon, living species: Grévy's zebra (''Equus grevyi''), the plains zebra (''E. quagga''), and the mountain zebra (''E. zebra''). Zebras share the genus ''Equus (genus), Equus'' with Wild horse, horses and Asinus, asses, the three groups being the only living members of the family Equidae. Zebra stripes come in different patterns, unique to each individual. Several theories have been proposed for the function of these patterns, with most evidence supporting them as a deterrent for biting flies. Zebras inhabit East Africa, eastern and southern Africa and can be found in a variety of habitats such as savannahs, grasslands, woodlands, shrublands, and mountainous areas. Zebras are primarily grazing (behaviour), grazers and can subsist on lower-quality vegetation. They are preyed on mainly by lions, and typically flee when threatened but ...
