Naja Melanoleuca
The forest cobra (''Naja melanoleuca''), also commonly called the black cobra and the black and white-lipped cobra, is a species of highly venomous snake in the family Elapidae. The species is native to Africa, mostly the central and western parts of the continent. It is the largest true cobra species with a record length of . Although it prefers lowland forest and moist savanna habitats, this cobra is highly adaptable and can be found in drier climates within its geographical range. It is a very capable swimmer and is often considered to be semi-aquatic. The forest cobra is a generalist in its feeding habits, having a highly varied diet: anything from large insects to small mammals and other reptiles. This species is alert, nervous and is considered to be a medically significant snake. When cornered or molested, it will assume the typical cobra warning posture by raising its fore body off the ground, spreading a narrow hood, and hissing loudly. Bites to humans are less common ...

Ancient Greek
Ancient Greek (, ; ) includes the forms of the Greek language used in ancient Greece and the classical antiquity, ancient world from around 1500 BC to 300 BC. It is often roughly divided into the following periods: Mycenaean Greek (), Greek Dark Ages, Dark Ages (), the Archaic Greece, Archaic or Homeric Greek, Homeric period (), and the Classical Greece, Classical period (). Ancient Greek was the language of Homer and of fifth-century Athens, fifth-century Athenian historians, playwrights, and Ancient Greek philosophy, philosophers. It has contributed many words to English vocabulary and has been a standard subject of study in educational institutions of the Western world since the Renaissance. This article primarily contains information about the Homeric Greek, Epic and Classical periods of the language, which are the best-attested periods and considered most typical of Ancient Greek. From the Hellenistic period (), Ancient Greek was followed by Koine Greek, which is regar ... [...More Info...] [...Related Items...] OR: [Wikipedia] [Google] [Baidu] |
Naja Mandalayensis
The Mandalay spitting cobra (''Naja mandalayensis''), also called the Burmese spitting cobra or Mandalay cobra, is a species of spitting cobra endemic to the Dry Zone in central Myanmar. Etymology ''Naja mandalayensis'' was first described by herpetologists Wolfgang Wüster and Joseph Bruno Slowinski in 2000. The generic name ''naja'' is a Latinisation of the Sanskrit word () meaning "cobra". The specific epithet ''mandalayensis'' is Latin and refers to the city of Mandalay, which is a major city within the range of Naja mandalayensis. Description This species of cobra is medium in length, and heavy bodied. The average length of an adult ranges from ; they can grow to . The head is elliptical, depressed, slightly distinct from the neck with a short, rounded snout and large nostrils. The body is compressed dorsoventrally and subcylindrical posteriorly. Its scales are smooth and strongly oblique. The eyes are moderate in size with round pupils. The body of this species is yellowi ...

Naja Atra
The Chinese cobra (''Naja atra''), also called the Taiwan cobra, is a species of cobra in the family Elapidae, found mostly in southern China and a couple of neighboring nations and islands. It is one of the most prevalent venomous snakes in China, which has caused many snakebite incidents to humans. Etymology and names ''Naja atra'' was first described by Danish physician, zoologist, and botanist Theodore Edward Cantor in 1842. The generic name ''naja'' is a Latinisation of the Sanskrit word () meaning "cobra". The specific epithet ''atra'' comes from the Latin term ''ater'', which means "dark", "black", or "gloomy". In Mandarin Chinese, the snake is known as ''Zhōnghuá yǎnjìngshé'' ( simplified: 中华眼镜蛇, traditional: 中華眼鏡蛇, lit. "Chinese spectacled snake", i.e. Chinese cobra), ''Zhōushān yǎnjìngshé'' (舟山眼鏡蛇, lit.

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. It is characterized by a distinctive circular or "monocle"-shaped marking on the hood, though the pattern can be highly variable or even absent in some individuals. It occupies a wide range of habitats, including forests, agricultural land, and areas near human settlements. It is responsible for a significant proportion of snakebite incidents and fatalities in its range, due to its potent neurotoxic venom and frequent proximity to human settlements. Some populations of the monocled cobra have the ability to spit venom with notable accuracy, though not all individuals exhibit this behavior. 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 ...

Naja Naja
The Indian cobra (''Naja naja /na''dʒa nadʒa/), also known commonly as the spectacled cobra, Asian cobra, or binocellate cobra, is a species of cobra, a venomous snake in the family Elapidae. The species is native to the Indian subcontinent, and is a member of the " big four" species that are responsible for the most snakebite cases in India. 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 several subgenera based on various fac ... [...More Info...] [...Related Items...] OR: [Wikipedia] [Google] [Baidu] |
Subgenus
In biology, a subgenus ( subgenera) is a taxonomic rank directly below genus. In the International Code of Zoological Nomenclature, a subgeneric name can be used independently or included in a species name, in parentheses, placed between the generic name and the specific epithet: e.g. the tiger cowry of the Indo-Pacific, ''Cypraea'' (''Cypraea'') ''tigris'' Linnaeus, which belongs to the subgenus ''Cypraea'' of the genus ''Cypraea''. However, it is not mandatory, or even customary, when giving the name of a species, to include the subgeneric name. In the International Code of Nomenclature for algae, fungi, and plants The ''International Code of Nomenclature for algae, fungi, and plants'' (ICN or ICNafp) is the set of rules and recommendations dealing with the formal botanical names that are given to plants, fungi and a few other groups of organisms, all tho ...

Cladogram
A cladogram (from Greek language, Greek ''clados'' "branch" and ''gramma'' "character") is a diagram used in cladistics to show relations among organisms. A cladogram is not, however, an Phylogenetic tree, evolutionary tree because it does not show how ancestors are related to descendants, nor does it show how much they have changed, so many differing evolutionary trees can be consistent with the same cladogram. A cladogram uses lines that branch off in different directions ending at a clade, a group of organisms with a last common ancestor. There are many shapes of cladograms but they all have lines that branch off from other lines. The lines can be traced back to where they branch off. These branching off points represent a hypothetical ancestor (not an actual entity) which can be inferred to exhibit the traits shared among the terminal taxa above it. This hypothetical ancestor might then provide clues about the order of evolution of various features, adaptation, and other e ...

Naja Multifasciata
''Naja'' is a genus of venomous elapid snakes commonly known as cobras (or "true cobras"). Various species occur throughout Africa, Southwest Asia, South Asia, and Southeast Asia. Several other elapid species are often called "cobras", such as the king cobra and the rinkhals, but they are not "true cobras", in that they do not belong to the genus ''Naja''. 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 species. Etymology The origin of the generic name, ''Naja'', is from the Sanskrit ''nāga'' (with a hard "g") meaning "snake". Some hold that the Sanskrit word is cognate with English "snake", Germanic: ''*snēk-a-'', Proto-IE: ''*(s)nēg-o-'', but Manfred Mayrhofer calls this etymology " ...

Naja Christyi
''Naja christyi'' (formerly ''Boulengerina christyi)'', commonly known as the Congo water cobra or Christy's water cobra, is a species of venomous snakes belonging to the family Elapidae. The species is native to Sub-Saharan Africa. This species was formerly in the genus ''Boulengerina'', but more recent research by Wallach et al. has shown that ''Boulengerina'' is actually a subgenus and ''Boulengerina christyi'' is a synonym of ''Naja christyi''.
