Naja Multifasciatus
''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 ...

Miocene
The Miocene ( ) is the first geological epoch of the Neogene Period and extends from about (Ma). The Miocene was named by Scottish geologist Charles Lyell; the name comes from the Greek words (', "less") and (', "new") and means "less recent" because it has 18% fewer modern marine invertebrates than the Pliocene has. The Miocene is preceded by the Oligocene and is followed by the Pliocene. As Earth went from the Oligocene through the Miocene and into the Pliocene, the climate slowly cooled towards a series of ice ages. The Miocene boundaries are not marked by a single distinct global event but consist rather of regionally defined boundaries between the warmer Oligocene and the cooler Pliocene Epoch. During the Early Miocene, the Arabian Peninsula collided with Eurasia, severing the connection between the Mediterranean and Indian Ocean, and allowing a faunal interchange to occur between Eurasia and Africa, including the dispersal of proboscideans into Eurasia. During the ... [...More Info...] [...Related Items...] OR: [Wikipedia] [Google] [Baidu] |
Monotypic
In biology, a monotypic taxon is a taxonomic group (taxon) that contains only one immediately subordinate taxon. A monotypic species is one that does not include subspecies or smaller, infraspecific taxa. In the case of genera, the term "unispecific" or "monospecific" is sometimes preferred. In botanical nomenclature, a monotypic genus is a genus in the special case where a genus and a single species are simultaneously described. In contrast, an oligotypic taxon contains more than one but only a very few subordinate taxa. Examples Just as the term ''monotypic'' is used to describe a taxon including only one subdivision, the contained taxon can also be referred to as monotypic within the higher-level taxon, e.g. a genus monotypic within a family. Some examples of monotypic groups are: Plants * In the order Amborellales, there is only one family, Amborellaceae and there is only one genus, '' Amborella'', and in this genus there is only one species, namely ''Amborella trichopoda. ...

Naja Oxiana
The Caspian cobra (''Naja oxiana''), also called the Central Asian cobra, ladle snake, Oxus cobra, or Russian cobra, is a species of venomous snake in the family Elapidae. The species is endemic to Central Asia. Described by Karl Eichwald in 1831, it was for many years considered a subspecies of the Indian cobra until genetic analysis revealed it to be a distinct species. Taxonomy Baltic German naturalist Karl Eichwald described the Caspian cobra originally as ''Tomyris oxiana'' in 1831. Russian naturalist Alexander Strauch placed it in the genus ''Naja'' in 1868. The generic name ''naja'' is a Latinisation of the Sanskrit word () meaning "cobra". The specific epithet ''oxiana'' is derived from the word in Latin or () in Greek, and refers to the ancient name of the river Amu Darya which flows along Afghanistan`s northern border separating it from Tajikistan and Uzbekistan before turning northwest into Turkmenistan and flows from there into the southern remnants of the Aral Sea ...

Forest Cobra
The forest cobra (''Naja melanoleuca''), also commonly called the black cobra and the black and white-lipped cobra, is a species of 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 very dangerous 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 than from othe ... [...More Info...] [...Related Items...] OR: [Wikipedia] [Google] [Baidu] |
Manfred Mayrhofer
Manfred Mayrhofer (26 September 1926 – 31 October 2011) was an Austrian Indo-Europeanist who specialized in Indo-Iranian languages. Mayrhofer served as professor emeritus at the University of Vienna. He is noted for his etymological dictionary of Sanskrit. Mayrhofer was born in Linz and studied Indo-European and Semitic languages, Semitic linguistics and philosophy at the University of Graz, where he received his Ph.D. in 1949. From 1953 to 1963 he taught at the University of Würzburg, and from 1963 to 1966 he was a professor at Saarland University. In 1966 he returned to Austria, serving as professor at the University of Vienna until his retirement in 1990. He died in Vienna at the age of 85.

Proto-Indo-European Language
Proto-Indo-European (PIE) is the reconstructed common ancestor of the Indo-European language family. Its proposed features have been derived by linguistic reconstruction from documented Indo-European languages. No direct record of Proto-Indo-European exists. Far more work has gone into reconstructing PIE than any other proto-language, and it is the best understood of all proto-languages of its age. The majority of linguistic work during the 19th century was devoted to the reconstruction of PIE or its daughter languages, and many of the modern techniques of linguistic reconstruction (such as the comparative method) were developed as a result. PIE is hypothesized to have been spoken as a single language from 4500 BC to 2500 BC during the Late Neolithic to Early Bronze Age, though estimates vary by more than a thousand years. According to the prevailing Kurgan hypothesis, the original homeland of the Proto-Indo-Europeans may have been in the Pontic–Caspian steppe of ...

Cognate (etymology)
In historical linguistics, cognates or lexical cognates are sets of words in different languages that have been inherited in direct descent from an etymological ancestor in a common parent language. Because language change can have radical effects on both the sound and the meaning of a word, cognates may not be obvious, and often it takes rigorous study of historical sources and the application of the comparative method to establish whether lexemes are cognate or not. Cognates are distinguished from loanwords, where a word has been borrowed from another language. The term ''cognate'' derives from the Latin noun '' cognatus blood relative'. Characteristics Cognates need not have the same meaning, which may have changed as the languages developed independently. For example English '' starve'' and Dutch '' sterven'' 'to die' or German '' sterben'' 'to die' all descend from the same Proto-Germanic verb, '' *sterbaną'' 'to die'. Cognates also do not need to look or sound similar ... [...More Info...] [...Related Items...] OR: [Wikipedia] [Google] [Baidu] |
Sanskrit
Sanskrit (; attributively , ; nominally , , ) is a classical language belonging to the Indo-Aryan branch of the Indo-European languages. It arose in South Asia after its predecessor languages had diffused there from the northwest in the late Bronze Age. Sanskrit is the sacred language of Hinduism, the language of classical Hindu philosophy, and of historical texts of Buddhism and Jainism. It was a link language in ancient and medieval South Asia, and upon transmission of Hindu and Buddhist culture to Southeast Asia, East Asia and Central Asia in the early medieval era, it became a language of religion and high culture, and of the political elites in some of these regions. As a result, Sanskrit had a lasting impact on the languages of South Asia, Southeast Asia and East Asia, especially in their formal and learned vocabularies. Sanskrit generally connotes several Old Indo-Aryan language varieties. The most archaic of these is the Vedic Sanskrit found in the Rig Veda, a colle ...

Paranaja Multifasciata
The many-banded snake (''Naja multifasciata''), also known as the burrowing cobra is a species of venomous elapid snake. The species is found in the Republic of Congo, the Democratic Republic of Congo and Cameroon in Africa. Description Despite the common name, the species is not actually banded, but overall iridescent black, with cream colored blotching on each scale. The snakes grow to approximately in length. Venom Not much is known about their venom, but it is likely a neurotoxin, like many other elapid snakes. The genus ''Paranaja'' was synonymised with '' Naja'' in a recent molecular phylogenetic study, as this species is closely related to the forest cobra (''Naja melanoleuca'') Wüster, W., Crookes, S., Ineich, I., Mané, Y., Pook, C.E., Trape, J.-F. & Broadley D.G.

Boulengerina
''Boulengerina'' is a genus or subgenus of elapid venomous snakes known commonly as water cobras, so named because of their semiaquatic nature. The genus has two recognised species, which are native to central and southern Africa. Taxonomy Some recent molecular studies have suggested that the genus ''Boulengerina'' should be synonymised with the genus ''Naja'', because the water cobras are closely related to some species of ''Naja''. Wallach, Wüster and Broadley, re-ranked ''Boulengerina'' as a subgenus within ''Naja'' comprising the two species already recognised as forming genus ''Boulengerina'' plus ''Naja melanoleuca'', as ''Naja (Boulengerina) melanoleuca'', and the species formerly known as ''Paranaja multifasciata'', now ''Naja (Boulengerina) multifasciata''. Etymology The generic name, ''Boulengerina'', is in honor of Belgian-born British herpetologist George Albert Boulenger. Beolens B, Watkins M, Grayson M (2011). ''The Eponym Dictionary of Reptiles''.
