Giant Spitting Cobra
''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 "serpent". 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 (Ban ... [...More Info...]       [...Related Items...]     OR:     [Wikipedia]   [Google]   [Baidu]   |

Wolfgang Wüster
Wolfgang Wüster (born 1964) is a herpetologist and Professor in Zoology at Bangor University, UK. Wüster attained his bachelor's degree at the University of Cambridge in 1985 and his doctorate at the University of Aberdeen in 1990. His primary areas of research are the systematics and ecology of venomous snakes and the evolution of their venoms. He has authored approximately 180 scientific papers on varying herpetological subjects. Recent contributions have included descriptions of new species, especially of cobras, several studies into how natural selection drives the evolution of snake venoms, and demonstrating the likely vulnerability of Madagascar's native fauna to the skin toxins of the invasive Asian toad '' Duttaphrynus melanostictus''. He was the scientific editor for ''The Herpetological Journal'' (2002–2009), the scientific publication of the British Herpetological Society The British Herpetological Society (BHS) is an international herpetological society base ...

Antivenom
Antivenom, also known as antivenin, venom antiserum, and antivenom immunoglobulin, is a specific treatment for envenomation. It is composed of antibodies and used to treat certain venomous bites and stings. Antivenoms are recommended only if there is significant toxicity or a high risk of toxicity. The specific antivenom needed depends on the species involved. It is given by injection. Side effects may be severe. They include serum sickness, shortness of breath, and allergic reactions including anaphylaxis. Antivenom is traditionally made by collecting venom from the relevant animal and injecting small amounts of it into a domestic animal. The antibodies that form are then collected from the domestic animal's blood and purified. Versions are available for spider bites, snake bites, fish stings, and scorpion stings. Due to the high cost of producing antibody-based antivenoms and their short shelf lives when not refrigerated, alternative methods of production of antiven ...

Toxin
A toxin is a naturally occurring poison produced by metabolic activities of living cells or organisms. They occur especially as proteins, often conjugated. The term was first used by organic chemist Ludwig Brieger (1849–1919), derived from '' toxic''. Toxins can be small molecules, peptides, or proteins that are capable of causing disease on contact with or absorption by body tissues interacting with biological macromolecules such as enzymes or cellular receptors. They vary greatly in their toxicity, ranging from usually minor (such as a bee sting) to potentially fatal even at extremely low doses (such as botulinum toxin). Terminology Toxins are often distinguished from other chemical agents strictly based on their biological origin. Less strict understandings embrace naturally occurring inorganic toxins, such as arsenic. Other understandings embrace synthetic analogs of naturally occurring organic poisons as toxins, and may or may not embrace naturally oc ...

Cytotoxin
Cytotoxicity is the quality of being toxic Toxicity is the degree to which a chemical substance or a particular mixture of substances can damage an organism. Toxicity can refer to the effect on a whole organism, such as an animal, bacterium, or plant, as well as the effect on a subst ... to cells. Examples of toxic agents are toxic metals, toxic chemicals, microbe neurotoxins, radiation particles and even specific neurotransmitters when the system is out of balance. Also some types of drugs, e.g alcohol (drug), alcohol, and some venom, e.g. from the Bitis arietans, puff adder (''Bitis arietans'') or brown recluse spider (''Loxosceles reclusa'') are toxic to cells. Cell physiology Treating cells with the cytotoxic compound can result in a variety of prognoses. The cells may undergo necrosis, in which they lose membrane integrity and die rapidly as a result of cell lysis. The cells can stop actively growing and dividing (a decrease in cell viability), or the cells can activa ...

Neurotoxin
Neurotoxins are toxins that are destructive to nervous tissue, nerve tissue (causing neurotoxicity). Neurotoxins are an extensive class of exogenous chemical neurological insult (medical), insultsSpencer 2000 that can adversely affect function in both developing and mature nervous tissue.Olney 2002 The term can also be used to classify endogenous compounds, which, when abnormally contacted, can prove neurologically toxic. Though neurotoxins are often neurologically destructive, their ability to specifically target neural components is important in the study of nervous systems. Common examples of neurotoxins include lead, ethanol (drinking alcohol), glutamate,Choi 1987 nitric oxide, botulinum toxin (e.g. Botox), tetanus toxin,Simpson 1986 and tetrodotoxin. Some substances such as nitric oxide and glutamate are in fact essential for proper function of the body and only exert neurotoxic effects at excessive concentrations. Neurotoxins inhibit neuron control over ion concentrations ... [...More Info...]       [...Related Items...]     OR:     [Wikipedia]   [Google]   [Baidu]   |

Red Spitting Cobra
The red spitting cobra (''Naja pallida'') is a species of spitting cobra native to Africa. Description This medium-sized cobra attains lengths between , but may grow to a maximum length of around in very rare cases. It is often thought of as an attractive species; it is usually bright salmon-red contrasted with a broad black throat band and subocular teardrop markings. However, the color of this species does have variation, which usually depends on where in Africa a particular specimen is found. For example, specimens from southern Kenya and northern Tanzania have an orange-red colour, with a broad, dark blue or black throat band. Some specimens may have two or three throat bands, but this is uncommon for specimens from East Africa. The ventral side is also reddish in colour, sometimes the throat area may be a creamy white. Specimens from other areas can be yellow, pinkish, pink-grey, pale red or steel grey. Most specimens will have a throat band, but it will fade or even somet ...

Dorsal Scale
In snakes, the dorsal scales are the longitudinal series of plates that encircle the body, but do not include the ventral scales. Campbell JA, Lamar WW (2004). ''The Venomous Reptiles of the Western Hemisphere''. Ithaca and London: Comstock Publishing Associates. 2 volumes. 870 pp. 1,500 plates. . When counting dorsal scales, numbers are often given for three points along the body, for example 19:21:17. These numbers correspond to the number of dorsal scales around the body at a head's length behind the head, at midbody and at a head's length before the vent. If only one number is given, it is for the midbody count. Dorsal scale are easiest to count diagonally, starting with the paraventral scale row. In doing so, it is often noted that certain scale rows are raised, keeled or smooth as opposed to the others.U.S. Navy (1991). ''Poisonous Snakes of the World''. United States Government.
