Venomous Snake
Venomous snakes are species of the suborder Serpentes that are capable of producing venom, which they use for killing prey, for defense, and to assist with digestion of their prey. The venom is typically delivered by injection using hollow or grooved fangs, although some venomous snakes lack well-developed fangs. Common venomous snakes include the families Elapidae, Viperidae, Atractaspididae, and some of the Colubridae. The toxicity of venom is mainly indicated by murine , while multiple factors are considered to judge the potential danger to humans. Other important factors for risk assessment include the likelihood that a snake will bite, the quantity of venom delivered with the bite, the efficiency of the delivery mechanism, and the location of a bite on the body of the victim. Snake venom may have both neurotoxic and hemotoxic properties. There are about 600 venomous snake species in the world. Evolution The evolutionary history of venomous snakes can be traced back to ...

Snake Bite
A snakebite is an injury caused by the bite of a snake, especially a venomous snake. A common sign of a bite from a venomous snake is the presence of two puncture wounds from the animal's fangs. Sometimes venom injection from the bite may occur. This may result in redness, swelling, and severe pain at the area, which may take up to an hour to appear. Vomiting, blurred vision, tingling of the limbs, and sweating may result. Most bites are on the hands, arms, or legs. Fear following a bite is common with symptoms of a racing heart and feeling faint. The venom may cause bleeding, kidney failure, a severe allergic reaction, tissue death around the bite, or breathing problems. Bites may result in the loss of a limb or other chronic problems or even death. The outcome depends on the type of snake, the area of the body bitten, the amount of snake venom injected, the general health of the person bitten and whether or not anti-venom serum has been administered by a doctor in a ...

India
India, officially the Republic of India (Hindi: ), is a country in South Asia. It is the seventh-largest country by area, the second-most populous country, and the most populous democracy in the world. Bounded by the Indian Ocean on the south, the Arabian Sea on the southwest, and the Bay of Bengal on the southeast, it shares land borders with Pakistan to the west; China, Nepal, and Bhutan to the north; and Bangladesh and Myanmar to the east. In the Indian Ocean, India is in the vicinity of Sri Lanka and the Maldives; its Andaman and Nicobar Islands share a maritime border with Thailand, Myanmar, and Indonesia.

Russell's Viper
Russell's viper (''Daboia russelii''), is a venomous snake in the family Viperidae native to the Indian subcontinent and one of the big four snakes in India. It was described in 1797 by George Shaw and Frederick Polydore Nodder, and named after Patrick Russell, who wrote about it in his 1796 work ''An account of Indian serpents, collected on the coast of Coromandel''. Taxonomy English naturalist George Shaw—with illustrator Frederick Polydore Nodder—in ''The Naturalist's Miscellany: Or, Coloured Figures Of Natural Objects; Drawn and Described Immediately From Nature'' formally described the species in 1797 as ''Coluber russelii'', from a specimen presented to the British Museum by Scottish herpetologist Patrick Russell. Russell had written of the species in his 1796 work ''An account of Indian serpents, collected on the coast of Coromandel'', confirming its highly venomous nature by experimenting on chickens and dogs.

Common Krait
The common krait (''Bungarus caeruleus''), also known as Bengal krait, is a species of highly venomous elapid snake of the genus ''Bungarus'' native to the Indian subcontinent. It is a member of the "Big Four" species that inflict the most snakebites on humans in Pakistan, India and Bangladesh. Description The average length of the common krait is , but it can grow to . Males are longer than females, with proportionately longer tails. The head is flat and the neck hardly evident. The body is cylindrical, tapering towards the tail. The tail is short and rounded. The eyes are rather small, with rounded pupils, indistinguishable in life. The head shields are normal, with no loreals; four shields occur along the margin of the lower lip; the third and fourth supraoculars touch the eye. The scales are highly polished, in 15-17 rows; the vertebral row is distinctly enlarged and hexagonal. Ventrals number 185-225 and caudals 37-50, and are entire (intact). Their colouration is general ... [...More Info...] [...Related Items...] OR: [Wikipedia] [Google] [Baidu] |
Indian Cobra
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 se ...

Snake Antivenom
Snake antivenom is a medication made up of antibodies used to treat snake bites by venomous snakes. It is a type of antivenom. It is a biological product that typically consists of venom neutralizing antibodies derived from a host animal, such as a horse or sheep. The host animal is hyperimmunized to one or more snake venoms, a process which creates an immunological response that produces large numbers of neutralizing antibodies against various components (toxins) of the venom. The antibodies are then collected from the host animal, and further processed into snake antivenom for the treatment of envenomation. It is on the World Health Organization's List of Essential Medicines. Production Antivenoms are typically produced using a donor animal, such as a horse or sheep. The donor animal is hyperimmunized with non-lethal doses of one or more venoms to produce a neutralizing antibody response. Then, at certain intervals, the blood from the donor animal is collected and neutra ... [...More Info...] [...Related Items...] OR: [Wikipedia] [Google] [Baidu] |
