Russell’s Viper Snack Information In English.
Vipers are mostly found in open areas. This is a major cause of death due to snakebite, as they are mostly found in agricultural lands. Where human contact and rodents are abundant. This snake grows to a maximum of 4 feet and is outlined with three rows of reddish-brown spots in black and again in white. These snakes lie calmly and slowly on the ground.
There are several species and subspecies of vipers. Also, these snakes lie in a cool place during the day and come out to hunt at night. The venom of the cobra is very toxic, if a person does not receive proper treatment within 1 to 2 hours of being bitten by a snake, he can die. So let's look at more detailed information.
Russell’s Viper Snack Appearance in English
The head is flattened, triangular, and distinct from the neck. The snout is blunt, rounded, and raised. The nostrils are large, each in the middle of a large, single nasal scale. The lower edge of the nasal scale touches the nasorostral scale. The supranasal scale has a strong crescent shape and separates the nasal from the nasorostral scale anteriorly. The rostral scale is as broad as it is high.
The crown of the head is covered with irregular, strongly fragmented scales. The supraocular scales are narrow, single, and separated by six to nine scales across the head. The eyes are large, flecked with yellow or gold, and surrounded by 10–15 circumorbital scales. The snake has 10–12 supralabials, the fourth and fifth of which are significantly larger.

The eyes are large, flecked with yellow or gold, and surrounded by 10–15 circumorbital scales. The snake has 10–12 supralabials, the fourth and fifth of which are significantly larger.
The eye is separated from the supralabials by three or four rows of suboculars. Of the two pairs of chin shields, the front pair is notably enlarged. The two maxillary bones support at least two and at the most five or six pairs of fangs at a time: the first are active and the rest replacements. The fangs attain a length of 16.5 mm in the average specimen.
The body is stout, the cross-section of which is rounded to circular. The dorsal scales are strongly keeled; only the lowest row is smooth. Mid-body, the dorsal scales number 27–33. The ventral scales number 153–180. The anal plate is not divided. The tail is short—about 14% of the total length—with the paired subcaudals numbering 41–68.
Dorsally, the color pattern consists of a deep yellow, tan, or brown ground color, with three series of dark brown spots that run the length of the body. Each of these spots has a black ring around it, the outer border of which is intensified with a rim of white or yellow. The dorsal spots, which usually number 23–30, may grow together, while the side spots may break apart.

The head has a pair of distinct dark patches, one on each temple, together with a pinkish, salmon, or brownish V or X marking that forms an apex towards the snout. Behind the eye is a dark streak, outlined in white, pink, or buff. The venter is white, whitish, yellowish, or pinkish, often with an irregular scattering of dark spots.
Russell's viper grows to a maximum body and tail length of 166 cm and averages about 120 cm in mainland Asia. In islands, it is slightly shorter on average. It is more slender than most vipers. The following dimensions for a "fair-sized adult specimen" were reported in 1937:

Russell’s Viper Snack Naming in English
The species is named after Patrick Russell, a Scottish herpetologist who first described many of India's snakes, and the name of the genus is from the Hindi word meaning "that lies hid", or "the lurker".
In English, common names of "D. russelii" include Russell's viper, chain viper, Indian Russell's viper, common Russell's viper, seven pacer, chain snake, and scissors snake.
In English, common names of "D. russelii" include Russell's viper, chain viper, Indian Russell's viper, common Russell's viper, seven pacer, chain snake, and scissors snake.
Russell's viper is found in India, Sri Lanka, Bangladesh, Nepal, and Pakistan. Populations from South-East Asia previously assigned to this species are now considered to be part of a different species, "Daboia siamensis". The type locality is listed as "India". More specifically, this would be the Coromandel Coast, by inference of Russell.
Within its range, it can be common in some areas, but scarce in others. In India, is abundant in Punjab, very common along the West Coast and its hills, in southern India especially in the state of Karnataka and north to Bengal. It is uncommon to rare in the Ganges valley, northern Bengal, and Assam.
Russell's viper is not restricted to any particular habitat, but does tend to avoid dense forests. The snake is mostly found in open, grassy or bushy areas, but may also be found in second growth forests, on forested plantations and farmland. It is most common in plains, coastal lowlands, and hills of suitable habitat. Generally, it is not found at altitude, but has been reported as far up as 2300–3000 m. Humid environments, such as marshes, swamps, and rain forests, are avoided.
This species is often found in highly urbanized areas and settlements in the countryside, the attraction being the rodents commensal with man.As a result, those working outside in these areas are most at risk of being bitten. "D. russelii" does not associate as closely with human habitation as "Naja" and "Bungarus" species.

Russell's viper is terrestrial and active primarily as a nocturnal forager. However, during cool weather, it alters its behavior and becomes more active during the day. Adults are reported to be slow and sluggish unless pushed beyond a certain limit, after which they can become very aggressive. Juveniles, though, are generally more nervous.
When threatened, they form a series of S-loops, raise the first third of the body, and produce a hiss that is supposedly louder than that of any other snake. When striking from this position, they can exert so much force that even a large individual can lift most of its body off the ground in the process. These snakes are strong and may react violently to being picked up. The bite may be a snap, or they may hang on for many seconds.
Although this genus does not have the heat-sensitive pit organs common to the Crotalinae, it is one of a number of viperines that are apparently able to react to thermal cues, further supporting the notion that they, too, possess a heat-sensitive organ. The identity of this sensor is not certain, but the nerve endings in the supranasal sac of these snakes resemble those found in other heat-sensitive organs....hieroglyph snipped...

Russell’s Viper Snack Reproduction in English
Russell's viper is ovoviviparous. Mating generally occurs early in the year, although pregnant females may be found at any time. The gestation period is more than six months. Young are produced from May to November, but mostly in June and July. It is a prolific breeder. Litters of 20–40 are common, although fewer offspring may occur, as few as one. The reported maximum is 75 in a single litter. At birth, juveniles are 215–260 mm in total length. The minimum total length for a gravid female is about 100 cm. It seems that sexual maturity is achieved in 2–3 years. In one case, it took a specimen nearly 4.5 hours to give birth to 11 young.
Russell’s Viper Snack Defense in English
Venom of this species is delivered by means of solenoglyphous dentition. The quantity of venom produced by individual specimens of "D. russelii" is considerable. Venom yields for adult specimens have been reported as 130–250 mg, 150–250 mg, and 21–268 mg. For 13 juveniles with an average total length of 79 cm, the venom yield ranged from 8 to 79 mg.
The LD50 in mice, which is used as a possible indicator of snake venom toxicity, is: 0.133 mg/kg intravenous, 0.40 mg/kg intraperitoneal, about 0.75 mg/kg subcutaneous. For most humans, a lethal dose is about 40–70 mg, well within the amount that can be delivered in one bite. In general, the toxicity depends on a combination of five different venom fractions, each of which is less toxic when tested separately.
Venom toxicity and bite symptoms in humans vary within different populations and over time. In another study, Meier and Theakston reported that the lethality of venom of Russell viper varies with change in route of injection, as their results predicts the LD50 of 0.4 mg/kg through intraperitoneal route, 0.75 mg/kg/subcutaneous route and 0.3 mg/kg through intravenous route.
Interesting Russell’s Viper Facts in English
It’s found across the Indian subcontinent in India, Sri Lanka, Bangladesh, Nepal, and Pakistan. In many regions such as Punjab and the west coast, it’s extremely common in open grasslands and farmland.They primarily feed on rodents such as rats, which means they can be found in highly urbanized areas and settlements in the countryside searching for prey.
Its habitat overlaps significantly with rural Indian communities, and this makes long grass a dangerous substrate for farmers and amblers alike.But is total annihilation a healthy response to a deadly snake? Their role in the ecosystem and, indirectly, the local economy, suggests there may be a better solution.
1. They are named, ‘The lurker’
The species name of the Russell’s Viper, russelii, is named in honour of Patrick Russell, a Scottish herpetologist who made significant contributions to the study of Indian serpents.
Taxonomically, it belongs to the family Viperidae and is closely related to other pit vipers, sharing a certain potency and social infamy with other members of the family.
The genus, Daboia, is derived from the Hindi word “Dabaiyya,” meaning “that lies hid,” or “the lurker,” referring to the snake’s cryptic nature. This is a snake that will sit and wait, perfectly camouflaged, in the grass until an unwitting rodent comes along. Unfortunately, sometimes an unwitting human comes along instead, and the results are often similar.
2. They’re very Dangerous
Snake venom typically evolved to rapidly put a stop to a small mammal’s ability to struggle, and therefore help protect the feeding snake from injury. Unfortunately, as mammals, this makes humans susceptible to the venom too, and so despite being from different worlds, snakes and humans became fearful of one another.
The Russell’s Viper is one of South Asia’s “Big Four” venomous snakes and is notorious for its lethal venom. Like other ‘most deadly snakes‘, it’s not just the potency but also the high chance of human contact that makes these snakes so deadly.
As such, they contribute significantly to overall snakebite deaths in India – causing an estimated 25,000 fatalities annually.
The venom is no joke; it causes acute kidney failure and blood clotting issues, and as such, research is desperately needed to determine the best dialysis treatment timing to minimize fatalities.
But while there are innumerable potential ways to reduce the danger, the current method is widespread culling.
And this is unfortunate because while the snake’s response to fear is generally to run away, the human response is to destroy everything that loosely resembles the source of the fear and kill everything around it too, just to be sure.
Ironically, this has always come around to bite people in the ass.
3. Their fangs grow over half an inch
Vipers have fangs, and the Russell’s Viper fangs reach a length of around 0.65 inch on average. This is enough to cause a painful bite, as well as administer their venom.
When threatened, they form a series of S-loops and can bite with a strong violent ‘snap’, or they can hang on for longer with their fangs.
They don’t always bite though, sometimes if they are stood on, they just want to get away!
4. They have a hidden heat radar
The Russell’s Viper does not have heat-sensitive pit organs like those common to pit vipers, but they are believed to have a heat-sensitive organ of some kind.
It’s unknown exactly what this is still, but the nerve endings in the supranasal sac are similar to those found in other heat-sensitive organs.
It helps them identify and hunt small mammals from their warm heat signature.
5. They help reduce disease spread
Snakes play a vital role in controlling the populations of various small mammals – in the case of the Russell’s viper, mainly rodents.
By regulating these numbers, they help maintain a balanced ecosystem and also aid in controlling the spread of diseases that rodents often carry, such as leptospirosis or hantavirus.
Further, since snakes don’t eat crops and rats do, replacing rat biomass with that of a more serpentine quality helps improve yields, too.
6. Reducing human contact is the key to coexistence
As much as we hate to admit it, small changes in our habits can have huge positive effects on the ecosystem.
In areas where these snakes are so prevalent, a handful of interventions can reduce lethal bites to almost zero.
First, getting torches to farmers will help them spot the snake before stepping on it, but cheap rubber boots will also go a long way to preventing bites from landing if they get too close.
Understanding the defensive nature of these bites is also important. Making cleared pathways provides people with routes to walk that don’t intersect with the ambush locations of the snake, and finally, providing local clinics and healers with the tools needed to address a bite can save lives very effectively.
7. Their venom may have other clinical uses
On top of the need to collect it for antivenom treatments, there are other potential applications for the compounds found in this snake’s venom.
This snake bite contains 63 individual proteins, from 12 protein families, making it a complex cocktail of poison. Understanding these is the key to making effective treatments for snake bites, but some of these proteins can have potential effects against other conditions.
At least one peptide has shown wound-healing properties, antimicrobial effects, and anti-inflammatory potential.

Antivenom alone is remarkably successful against
viper bites, so getting vials of it out to the right people is key.
Then, education about the importance of snakes in
the function of the ecosystem and their economic value as pest control is
crucial to reducing unnecessary interactions and culls.
And these snakes have clinical significance outside of their lethality.

8. They’re stunning!
Regardless of how terrifying they might be, there’s no denying how striking a Russel’s viper looks.
Elongated, red-brown eyespots pepper the earthy tones of its body, breaking up the shape and allowing it to disappear into the grass entirely.
These skins were sought after by leather companies in the West, who used local labourers to do the dirty and dangerous work of catching and killing the snakes. Once the market was established, millions of snakes were killed every year.
9. Russell’s vipers are prolific breeders
Luckily for the Russel’s viper, they are prolific reproducers. A single pregnant female can produce over 50 live young in a litter, rapidly replacing lost snakes in areas where there is plenty of food.
This is one of the reasons the snake is still doing so well across its range.
It’s listed as of ‘Least Concern’ by the IUCN, and though its numbers are thought to be decreasing, this rate isn’t yet thought to be a problem for the species
10. They have an impersonator
Success will often breed impersonators, and this is no different in the animal kingdom. Such is the success of the Russell’s Viper as a species, another snake now mimics its appearance.
The rough-scaled sand boa Eryx has taken on a very similar color pattern to resemble the venonmous viper, however it itself is entirely harmless.
