Naja Siamensis
The Indochinese spitting cobra (''Naja siamensis'') ( th, งูเห่า, pronounced: nguu hao) also called the Thai spitting cobra, Siamese spitting cobra, is a species of spitting cobra found in Southeast Asia. Description This is a medium-sized elapid, with a more slender build compared to most other cobras within the genus ''Naja''. The body colour of this species is variable from grey to brown to black, with white spots or stripes. The white patterning can be so prolific that it covers the majority of the snake. The highly distinctive black and white colour phase is common in central Thailand, specimens from western Thailand are mostly black, whereas individuals from elsewhere are usually brown. The hood mark can be spectacle-shaped, irregular or missing altogether, especially in adults. Adults average between in length, and can potentially reach lengths of , although this is considered rare. Body mass for adults can be tends to be around 1,600 grams. This species shou ...

Josephus Nicolaus Laurenti
Josephus Nicolaus Laurenti (4 December 1735, Vienna – 17 February 1805, Vienna) was an Austrian naturalist and zoologist of Italian origin. Laurenti is considered the auctor of the class Reptilia (reptiles) through his authorship of ' (1768) on the poisonous function of reptiles and amphibians. This was an important book in herpetology, defining thirty genera of reptiles; Carl Linnaeus's 10th edition of ''Systema Naturae'' in 1758 defined only ten genera. ''Specimen Medicum'' contains a description of the blind salamander (amphibian): ''Proteus anguinus'', purportedly collected from cave waters in Slovenia (or possibly western Croatia , image_flag = Flag of Croatia.svg , image_coat = Coat of arms of Croatia.svg , anthem = "Lijepa naša domovino"("Our Beautiful Homeland") , image_map = , map_caption = , capit ...); this description represented one of the first published accounts of a cave animal in the w ...

Afronaja
''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] |
Naja Guineensis
The black forest cobra (''Naja guineensis'') is a species of cobra in the genus ''Naja'' that is found in West Africa. This species was long thought to be identical to the forest cobra (''Naja melanoleuca''), but morphological and genetic differences have led to its recognition as a separate species. It differs from ''Naja melanoleuca'' in often having 17 rather than 19 midbody dorsal scale rows, a reduced number of dark ventral bands, and a tendency towards ontogenetic melanism. Description Adults are uniformly brownish black or black dorsally, or may display faint variegated lighter markings. Juveniles have much more pronounced light speckling or variegated banding. Ventrally, the throat is light, and is followed by several alternating dark and light bands (usually 2-3 discrete dark bands), the remainder of the ventral side is uniformly black. In adults, the light ventral bands often become heavily suffused with dark mottling and may become indistinguishable. The labial region ...

Naja Subfulva
The brown forest cobra (''Naja subfulva'') is a species of cobra in the genus ''Naja'' that is found in Central and East Africa. This species was long thought to be either identical to the forest cobra (''Naja melanoleuca''), or a subspecies thereof, but morphological and genetic differences have led to its recognition as a separate species. It differs from ''Naja melanoleuca'' and other forest cobras in usually having a brownish forebody, often with darker spots, and often a light ventral side and attentuated ventral banding. Description Adults of most populations have a brown forebody, gradually turning black towards the tail, often with spotting or mottling in the lighter parts. Adults from the Lake Victoria area and parts of the Congo Basin are entirely black dorsally. The sides and underside of the head are light, usually cream-coloured, and the labial scales have dark edges, although these can be indistinct in some populations. Ventral side may turn black posteriorly, or b ... [...More Info...] [...Related Items...] OR: [Wikipedia] [Google] [Baidu] |
Naja Savannula
The West African banded cobra (''Naja savannula'') is a species of cobra in the genus ''Naja'' that is found in West Africa. This species was previously thought to be identical to the forest cobra (''Naja melanoleuca''), but morphological and genetic differences have led to its recognition as a separate species. It differs from ''Naja melanoleuca'' and other forest cobras in having a series of 3–8 broad, semi-divided light bands across the anterior body. Description Brownish black or black dorsally, with a series of 3–8 broad, cream-coloured crossbands, each partly divided by a narrow black crossband. Midbody dorsal scale rows 19, Ventrals 211–226, subcaudals 67–73. Maximum recorded length 223 cm Distribution West Africa: primarily gallery forests in West African savannas and savanna woodlands; recorded from Senegal, Gambia, Guinea, Mali, Burkina Faso, Ivory Coast, Ghana, Togo, Benin, Niger, Nigeria, northern Cameroon and southern Chad Chad (; ar, تشاد , ; ...

Naja Annulata
''Naja annulata'' (formerly ''Boulengerina annulata''), commonly known as the banded water cobra or the ringed water cobra, is a species of water cobra native to western and central Africa. The species is one of the two species of water cobra in the world, the other one being the Congo water cobra (''Naja christyi''). Description It is a large, heavy-bodied snake with a short, broad and flat head with an indistinct canthus and distinct from the neck. It has medium-sized dark eyes with round pupils. The body is cylindrical; the tail is long. The scales are smooth and glossy, in 21–23 rows at midbody. Adults grow to an average of in length, but they can grow to a maximum of . Scales are smooth, indicating the largely aquatic life of this species. It is capable of spreading a narrow, yet impressive hood. Body colors are mostly glossy brown, grayish-brown, or reddish-brown with black bands all along the body. The belly is pale yellow, while the tail is wholly black. Distribution ...

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''. Wallach V, Wüster W, Broadley DG (2009)"In praise of subgenera: taxonomic status of cobras of the genus ''Naja'' Laurenti (Serpentes: Elapidae)".a''Zootaxa'' Magnolia Press. ''Zootaxa'' 2236: 26–36.

Naja 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 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 (biology), family Elapidae.

Naja Nigricincta
''Naja nigricincta'' is a species of spitting cobra in the genus ''Naja'', belonging to the family Elapidae. The species is native to the deserts and drier regions of southern Africa. The species is largely nocturnal, and is often found while crossing roads at night. There are two recognized subspecies. Taxonomy ''Naja nigricincta'' had long been considered to be a subspecies of the black-necked spitting cobra (''Naja nigricollis''), but morphological and genetic differences have led to its recognition as a separate species. Subspecies Two subspecies are currently recognized under ''Naja nigricincta''. The nominate subspecies ''N. n. nigricincta'', commonly known as the zebra spitting cobra, zebra cobra or western barred spitting cobra, is given its name because of the dark crossbars that run the length of the snake's body. The subspecies ''N. n. woodi'', commonly known as the black spitting cobra, woods black spitting cobra, is solid black and is found only in the desert areas o ...

Naja Mossambica
The Mozambique spitting cobra (''Naja mossambica'') is a highly venomous species of spitting cobra native to Africa. It is largely found in Angola, Botswana, Malawi, Mozambique, Namibia, South Africa, Tanzania, Zambia, and Zimbabwe. Taxonomy German naturalist Wilhelm Peters described this species in 1854. Description In color, the snake is slate to blue, olive or tawny black above, with some or all scales having black edging. Below, it is salmon pink to purple yellowish, with black bars across the neck and ventrals speckled or edged with brown or black; young specimens sometimes have pink or yellow bars on the throat. The average length of adults is between 90 cm and 105 cm (3–3½ feet), but the largest specimen measured was a male 154 cm (5 feet) long in Durban, KwaZulu-Natal, South Africa. Distribution This species is the most common cobra of the savanna regions of tropical and subtropical Africa. The distribution includes all of Mozambique; KwaZulu- ...

Naja Ashei
''Naja ashei'', commonly known as Ashe's spitting cobra or the giant spitting cobra, is a species of venomous snake in the family Elapidae. The species is native to Africa. It is the world's largest species of spitting cobra. Etymology and taxonomy The generic name, ''Naja'', is a Latinisation of the Sanskrit word ' (), meaning "cobra". The specific epithet, ''ashei'', honors the late James Ashe, who founded the Bio-Ken Snake Farm and was one of the first experts to suggest ''N. ashei'' was a new species.Beolens, Bo; Watkins, Michael; Grayson, Michael (2011). ''The Eponym Dictionary of Reptiles''. Baltimore: Johns Hopkins University Press. xiii + 296 pp. . (''Naja ashei'', p. 12). Differences from other spitting cobras were realized in the 1960s, but ''N. ashei'' was initially regarded by most as merely a brown-coloured form of the black-necked spitting cobra ('' N. nigricollis''). Thus, ''N. ashei'' was only classified as a distinct species in 2007, by Wolfgang Wüster (Bangor ... [...More Info...] [...Related Items...] OR: [Wikipedia] [Google] [Baidu] |
Naja Nigricollis
The black-necked spitting cobra (''Naja nigricollis'') is a species of spitting cobra found mostly in sub-Saharan Africa. They are moderately sized snakes that can grow to a length of in length. Their coloration and markings can vary considerably. They prey primarily on small rodents. They possess medically significant venom, although the mortality rate for untreated bites on humans is relatively low (~5–10%, in endemic regions under 1%). Like other spitting cobras, they can eject venom from their fangs when threatened (one drop over and more in perfect accuracy). The neurotoxic venom irritates the skin, causing blisters and inflammation, and can cause permanent blindness if the venom makes contact with the eyes and is not washed off. ''Naja nigricollis'' belongs to the cobra genus ''Naja'' under the family Elapidae. It previously included two subspecies that have been moved to the species ''Naja nigricincta'' – the zebra spitting cobra (''Naja nigricincta nigricincta'') a ...
