Nannopetersius is a genus of African tetras that occurs in Middle Africa. There are currently two described species.
Elephants are the largest existing land animals. Three living species are currently recognised: the African bush elephant, the African forest elephant, and the Asian elephant. They are an informal grouping within the proboscidean family Elephantidae. Elephantidae is the only surviving family of proboscideans; extinct members include the mastodons. Elephantidae also contains several extinct groups, including the mammoths and straight-tusked elephants. African elephants have larger ears and concave backs, whereas Asian elephants have smaller ears, and convex or level backs. The distinctive features of all elephants include a long proboscis called a trunk, tusks, large ear flaps, massive legs, and tough but sensitive skin. The trunk is used for breathing, bringing food and water to the mouth, and grasping objects. Tusks, which are derived from the incisor teeth, serve both as weapons and as tools for moving objects and digging. The large ear flaps assist in maintaining a constant body temperature as well as in communication. The pillar-like legs carry their great weight.
Human evolution is the evolutionary process within the history of primates that led to the emergence of Homo sapiens as a distinct species of the hominid family, which includes the great apes. This process involved the gradual development of traits such as human bipedalism and language, as well as interbreeding with other hominins, which indicate that human evolution was not linear but a web.
The giraffe is a tall African hoofed mammal belonging to the genus Giraffa. It is the tallest living terrestrial animal and the largest ruminant on Earth. Traditionally, giraffes were thought to be one species, Giraffa camelopardalis, with nine subspecies. Most recently, researchers proposed dividing giraffes into up to eight extant species due to new research into their mitochondrial and nuclear DNA, as well as morphological measurements. Seven other extinct species of Giraffa are known from the fossil record.
Protea cynaroides, also called the king protea, is a flowering plant. It is a distinctive member of Protea, having the largest flower head in the genus. The species is also known as giant protea, honeypot or king sugar bush. It is widely distributed in the southwestern and southern parts of South Africa in the fynbos region.
Madagascar, officially the Republic of Madagascar, and previously known as the Malagasy Republic, is an island country in the Indian Ocean, approximately 400 kilometres off the coast of East Africa across the Mozambique Channel. At 592,800 square kilometres (228,900 sq mi) Madagascar is the world's second-largest island country, after Indonesia. The nation consists of the island of Madagascar and numerous smaller peripheral islands. Following the prehistoric breakup of the supercontinent Gondwana, Madagascar split from the Indian subcontinent around 88 million years ago, allowing native plants and animals to evolve in relative isolation. Consequently, Madagascar is a biodiversity hotspot; over 90% of its wildlife is endemic.
The Congo River, formerly also known as the Zaire River, is the second longest river in Africa, shorter only than the Nile, as well as the second largest river in the world by discharge volume, following only the Amazon. It is also the world's deepest recorded river, with measured depths in excess of 220 m (720 ft). The Congo-Lualaba-Chambeshi River system has an overall length of 4,700 km (2,920 mi), which makes it the world's ninth-longest river. The Chambeshi is a tributary of the Lualaba River, and Lualaba is the name of the Congo River upstream of Boyoma Falls, extending for 1,800 km (1,120 mi).
Oryx is a genus consisting of four large antelope species called oryxes. Their pelage is pale with contrasting dark markings in the face and on the legs, and their long horns are almost straight. The exception is the scimitar oryx, which lacks dark markings on the legs, only has faint dark markings on the head, has an ochre neck, and has horns that are clearly decurved.
Homo is the genus that emerged in the genus Australopithecus that encompasses the extant species Homo sapiens, plus several extinct species classified as either ancestral to or closely related to modern humans, most notably Homo erectus and Homo neanderthalensis. The genus emerged with the appearance of Homo habilis just over 2 million years ago. Homo, together with the genus Paranthropus, is probably sister to Australopithecus africanus, which itself had previously split from the lineage of Pan, the chimpanzees.
Adansonia is a genus made up of eight species of medium to large deciduous trees known as baobabs. Previously classified within the family Bombacaceae, they are now placed in the Malvaceae. They are native to Madagascar, mainland Africa and Australia. Trees have also been introduced to other regions such as Asia. The generic name honours Michel Adanson, the French naturalist and explorer who described Adansonia digitata. The baobab is also known as the "upside down tree", a name that originates from several myths. They are among the most long-lived of vascular plants and have large flowers that are reproductive for a maximum of 15 hours. The flowers open around dusk; opening so quickly that movement can be detected by the naked eye and are faded by the next morning. The fruits are large, oval to round and berry-like and hold kidney-shaped seeds in a dry, pulpy matrix.
A rhinoceros, commonly abbreviated to rhino, is a member of any of the five extant species of odd-toed ungulates in the family Rhinocerotidae. Two of the extant species are native to Africa, and three to South and Southeast Asia.
The bushbuck is a common and a widespread species of antelope in Sub-Saharan Africa. Bushbuck are found in a wide range of habitats, such as rain forests, montane forests, forest-savanna mosaic, savanna, bushveld and woodland. Bushbuck stand about 90 centimetres (35 in) at the shoulder and weigh from 45 to 80 kilograms. They are generally solitary, territorial browsers.
The common eland, also known as the southern eland or eland antelope, is a savannah and plains antelope found in East and Southern Africa. It is a species of the family Bovidae and genus Taurotragus. An adult male is around 1.6 metres (5') tall at the shoulder and can weigh up to 942 kg (2,077 lb) with an average of 500–600 kg (1,100–1,300 lb), 340–445 kg (750–981 lb) for females). It is the second largest antelope in the world, being slightly smaller on average than the giant eland. It was scientifically described by Peter Simon Pallas in 1766.
The African elephant (Loxodonta) is a genus comprising two living elephant species, the African bush elephant and the smaller African forest elephant. Both are social herbivores with grey skin, but differ in the size and colour of their tusks and in the shape and size of their ears and skulls.
African tetras are a group of characiform fish exclusively found in Africa. This family contains about 18 genera and 119 species. Among the best known members are the Congo tetra, and African tigerfish.
The wildlife of Zimbabwe occurs foremost in remote or rugged terrain, in national parks and private wildlife ranches, in miombo woodlands and thorny acacia or kopje. The prominent wild fauna includes African buffalo, African bush elephant, black rhinoceros, southern giraffe, African leopard, lion, plains zebra, and several antelope species.
South Africa, officially the Republic of South Africa (RSA), is the southernmost country in Africa. With over 60 million people, the country is the world's 23rd-most populous nation and covers an area of 1,221,037 square kilometres. South Africa has three capital cities, with the executive, judicial and legislative branches of government based in Pretoria, Bloemfontein and Cape Town respectively. The largest city is Johannesburg. About 80% of South Africans are of indigenous Black African ancestry, divided among a variety of ethnic groups speaking different African languages. The remaining population consists of Africa's largest communities of European, Asian, and Multiracial ancestry.
William John Ansorge was a physician who worked in Angola and Uganda and is known for exploring the fauna of the African region. A large number of species have been named after him based on the specimens that he collected and sent back to England.
Nannopetersius ansorgii is a species of fish in the African tetra family, found in the central Rivers in Africa. The rivers in Africa are: the Benito (Mbini), the Chiloango, the Kouilou, the Loeme and the Ogooué rivers of Gabon and Equatorial Guinea and the Bengo and Congo River basins of Angola and Democratic Republic of the Congo. This species reaches a length of 7.0 cm (2.8 in).
Nannopetersius lamberti is a species of fish in the African tetra family, found in the African river basins of the Ntem, the Ogowe, the Nyanga and the Kouilou Rivers. This species reaches a length of 7.0 cm (2.8 in).
Nannopetersius mutambuei is a species of fish in the African tetra family, only found in the Inkisi River upstream of the Sanga dam in the lower Congo River basin, in the Democratic Republic of the Congo. This species reaches a length of 12.0 cm (4.7 in).
