Naja Anchietae
Anchieta's cobra (''Naja anchietae''), sometimes referred to as the Angolan cobra, is a species of venomous snake in the family Elapidae. The species is native to Southern Africa. Taxonomy Anchieta's cobra was first described by Portuguese zoologist José Vicente Barbosa du Bocage in 1879. The specific epithet, ''anchietae'', refers to José Alberto de Oliveira Anchieta, a Portuguese explorer of Africa. Along with the snouted cobra (''N. haje annulifera''), Anchieta's cobra (''N. haje anchietae'') was formerly regarded as subspecies of the Egyptian cobra (''Naja haje''), but have since been proven to be distinct species. Based on analysis of character morphology, Broadley (1995) raised ''Naja annulifera'' to species level, with ''Naja annulifera anchietae'' as a subspecies. More research by Broadley & Wüster (2004) using both analysis of morphology character and mitochondrial DNA (mtDNA) further confirmed that ''Naja annulifera'' was a distinct species, but data obtained al ...

José Vicente Barbosa Du Bocage
José Vicente Barbosa du Bocage (2 May 1823 – 3 November 1907) was a Portuguese zoologist and politician. He was the curator of Zoology at the Museu Nacional de Lisboa in Lisbon. He published numerous works on mammals, birds, and fishes. In the 1880s he became the Minister of the Navy and later the Minister for Foreign Affairs for Portugal. The zoology collection at the Lisbon Museum is called the Bocage Museum in his honor. Du Bocage was born in Funchal, Madeira. He studied at the University of Coimbra from 1839 to 1846.

In 1858, he became also the scientific director and curator of Zoology of the Natural History Museum of the Polytechnic School. which was established as a support for the chair. His work at the Museum consisted in acquiring, describing and coordi ... [...More Info...] [...Related Items...] OR: [Wikipedia] [Google] [Baidu] |
Southern Africa
Southern Africa is the southernmost subregion of the African continent, south of the Congo and Tanzania. The physical location is the large part of Africa to the south of the extensive Congo River basin. Southern Africa is home to a number of river systems; the Zambezi River being the most prominent. The Zambezi flows from the northwest corner of Zambia and western Angola to the Indian Ocean on the coast of Mozambique. Along the way, the Zambezi River flows over the mighty Victoria Falls on the border between Zambia and Zimbabwe. Victoria Falls is one of the largest waterfalls in the world and a major tourist attraction for the region. Southern Africa includes both subtropical and temperate climates, with the Tropic of Capricorn running through the middle of the region, dividing it into its subtropical and temperate halves. Countries commonly included in Southern Africa include Angola, Botswana, the Comoros, Eswatini, Lesotho, Madagascar, Malawi, Mauritius, Mozamb ...

Naja Kaouthia
The monocled cobra (''Naja kaouthia''), also called monocellate cobra and Indian spitting cobra, is a venomous cobra species widespread across South and Southeast Asia and listed as Least Concern on the IUCN Red List. Taxonomy The scientific name ''Naja kaouthia'' was proposed by René Lesson in 1831, when he described the monocled cobra as a beautiful snake that is distinct from the spectacled cobra, with 188 ventral scales and 53 pairs of caudal scales. Since then, several monocled cobras were described under different scientific names: * In 1834, John Edward Gray published Thomas Hardwicke's first illustration of a monocled cobra under the trinomial ''Naja tripudians'' var. ''fasciata''. * In 1839, Theodore Edward Cantor described a brownish monocled cobra with numerous faint yellow transverse stripes and a hood marked with a white ring under the binomial ''Naja larvata'', found in Bombay, Calcutta, and Assam. Several varieties of monocled cobras were described under the ... [...More Info...] [...Related Items...] OR: [Wikipedia] [Google] [Baidu] |
Naja Naja
The Indian cobra (''Naja naja''), also known as the spectacled cobra, Asian cobra, or binocellate cobra, is a species of cobra found in India, Pakistan, Bangladesh, Sri Lanka, Nepal, and Bhutan, and a member of the "big four" species that are responsible for the most snakebite cases in India. It is distinct from the king cobra which belongs to the monotypic genus ''Ophiophagus''. The Indian cobra is revered in Hindu mythology and culture, and is often seen with snake charmers. It is a protected species under the '' Indian Wildlife Protection Act'' (1972). Taxonomy The generic name and the specific epithet ''naja'' is a Latinisation of the Sanskrit word () meaning "cobra". The Indian cobra is classified under the genus ''Naja'' of the family Elapidae. The genus was first described by Josephus Nicolaus Laurenti in 1768. The species ''Naja naja'' was first described by the Swedish physician, zoologist, and botanist Carl Linnaeus in 1758. The genus ''Naja'' was split into s ...

Naja (subgenus)
''Naja'' is a genus of venomous elapid snakes commonly known as cobras (or "true cobras"). Members of the genus ''Naja'' are the most widespread and the most widely recognized as "true" cobras. Various species occur in regions throughout Africa, Southwest Asia, South Asia, and Southeast Asia. Several other elapid species are also called "cobras", such as the king cobra (''Ophiophagus hannah'') and the rinkhals (''Hemachatus haemachatus''), but neither are true cobras, in that they do not belong to the genus ''Naja'', but instead each belong to monotypic genera ''Hemachatus'' (the rinkhals) and ''Ophiophagus'' (the king cobra/hamadryad). Until recently, the genus ''Naja'' had 20 to 22 species, but it has undergone several taxonomic revisions in recent years, so sources vary greatly. Wide support exists, though, for a 2009 revision that synonymised the genera ''Boulengerina'' and '' Paranaja'' with ''Naja''. According to that revision, the genus ''Naja'' now includes 38 specie ... [...More Info...] [...Related Items...] OR: [Wikipedia] [Google] [Baidu] |

Cape Cobra
The Cape cobra (''Naja nivea''), also called the yellow cobra, is a moderate-sized, highly venomous species of cobra inhabiting a wide variety of biomes across southern Africa including arid savanna, fynbos, bushveld, desert and semi-desert regions. The species is diurnal and is a feeding generalist, preying on a number of different species and carrion. Predators of this species include birds of prey, honey badgers and various species of mongoose. The Cape cobra is also known as the "geelslang" (yellow snake) and "bruinkapel" (brown cobra) in South Africa. Afrikaans speaking South Africans also refer to the Cape cobra as "koperkapel" ("copper cobra"), mainly because of a rich yellow colour variation. This species has no known subspecies. Etymology ''Naja nivea'' was first described by Swedish zoologist Carl Linnaeus in 1758. The genus, generic name ''naja'' is a Latinisation of the Sanskrit word () meaning "cobra". The species, specific epithet ''nivea'' is derived from the ... [...More Info...] [...Related Items...] OR: [Wikipedia] [Google] [Baidu] |
Mitochondrial DNA
Mitochondrial DNA (mtDNA or mDNA) is the DNA located in mitochondria, cellular organelles within eukaryotic cells that convert chemical energy from food into a form that cells can use, such as adenosine triphosphate (ATP). Mitochondrial DNA is only a small portion of the DNA in a eukaryotic cell; most of the DNA can be found in the cell nucleus and, in plants and algae, also in plastids such as chloroplasts. Human mitochondrial DNA was the first significant part of the human genome to be sequenced. This sequencing revealed that the human mtDNA includes 16,569 base pairs and encodes 13 proteins. Since animal mtDNA evolves faster than nuclear genetic markers, it represents a mainstay of phylogenetics and evolutionary biology. It also permits an examination of the relatedness of populations, and so has become important in anthropology and biogeography. Origin Nuclear and mitochondrial DNA are thought to be of separate evolutionary origin, with the mtDNA being derive ... [...More Info...] [...Related Items...] OR: [Wikipedia] [Google] [Baidu] |
Egyptian Cobra
The Egyptian cobra (''Naja haje''), also known as Ouraeus ''(derived from the Ancient Greek word: ''οὐραῖος'' - )'', is one of the most venomous snakes in North Africa, which has caused many snakebite incidents to humans. It averages roughly , with the longest recorded specimen measuring . Etymology and taxonomy ''Naja haje'' was first described by Swedish zoologist Carl Linnaeus in 1758. The generic name ''naja'' is a Latinisation of the Sanskrit word () meaning " cobra". The specific epithet ''haje'' is derived from the Arabic word ''ḥayya'' (حية) which literally means "snake". The snouted cobra (''Naja annulifera'') and Anchieta's cobra (''Naja anchietae'') were formerly regarded as subspecies of ''Naja haje'', but have since been shown to be distinct species. The Arabian populations were long recognised as a separate subspecies, ''Naja haje arabica'', and the black populations from Morocco sometimes as ''Naja haje legionis''. A recent study found that the Ara ... [...More Info...] [...Related Items...] OR: [Wikipedia] [Google] [Baidu] |
Subspecies
In biological classification, subspecies is a rank below species, used for populations that live in different areas and vary in size, shape, or other physical characteristics ( 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 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 ranks, such as variety, may be named. In bacteriology and virology, under standard bacterial nomenclature and virus nomenclature, there are recommendations but not strict requirements for recognizing other important infraspecific ranks. A taxonomist decides whe ... [...More Info...] [...Related Items...] OR: [Wikipedia] [Google] [Baidu] |
Snouted Cobra
The snouted cobra (''Naja annulifera''), also called the banded Egyptian cobra, is a highly venomous species of cobra found in Southern Africa. Description The snouted cobra is a relatively large species. Adult specimens average between in length, but they may reach lengths of . Colouration of dorsal scales may vary from yellowish to greyish-brown, dark brown or blue-black. Ventral scale colouration is yellow with darker mottles. A banded phase occurs throughout the species' range and is blue-black with 7-11 yellow to yellow-brown cross bars, the lighter bands being half the width of the darker bands. The latter colour phase is more common in males. Ventrally, it is yellow mottled with black. A darker throat band is present and is usually more prominent in juveniles. Scalation Midbody scales are in 19 rows (rarely 21) with 175-203 ventrals. There are 51-65 paired subcaudals and the anal shield is entire. There are seven (sometimes eight) upper labials that do not enter the eye, ... [...More Info...] [...Related Items...] OR: [Wikipedia] [Google] [Baidu] |
José Alberto De Oliveira Anchieta
José Alberto de Oliveira Anchieta (variations José d'Anchieta, José Anchieta, José de Anchieta - b. October 9, 1832 in Lisbon, Kingdom of Portugal, d. September 14, 1897 in Caconda, Portuguese Angola) was a 19th-century Portuguese explorer and naturalist who, between 1866 and 1897, travelled extensively in Portuguese Angola, Africa, collecting animals and plants. His specimens from Angola and Mozambique were sent out to Portugal, where they were later examined by several zoologists and botanists, chiefly among them J.V. Barboza du Bocage. Life Anchieta was born in 1832, in Lisbon, and started his studies in mathematics at the University of Coimbra. Due to his fierce independence and eccentric character, however, he did not adapt well and moved to the Escola Politécnica de Lisboa (Polytechnic School of Lisbon). In 1857, one of his closest friends moved to Portuguese Cape Verde, a Portuguese colony and a group of islands in the Atlantic Ocean in West Africa, and Anchieta w ...
