Russell's viper

Russell's viper (Daboia russelii) is a highly 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 edit

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.[1] 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. He added the native people called it katuka retula poda.[2]

Analysis of morphological and mitochondrial DNA data shows that the eastern subspecies of D. russelii should be considered a separate species, Daboia siamensis.[3]

A number of other subspecies may be encountered in literature,[4] including:

  • D. s. formosensis (Maki, 1931) – found in Thailand (considered a synonym of D. siamensis).
  • D. s. limitis (Mertens, 1927) – found in Indonesia (considered a synonym of D. siamensis).
  • D. r. pulchella (Gray, 1842) – found in Sri Lanka (considered a synonym of D. russelii).
  • D. r. nordicus (Deraniyagala, 1945) – found in northern India (considered a synonym of D. russelii).

The correct spelling of the species, D. russelii, has been, and still is, a matter of debate. Shaw and Nodder (1797), in their account of the species Coluber russelii, named it after Patrick Russell, but apparently misspelled his name, using only one "L" instead of two. Russell (1727–1805) was the author of An Account of Indian Serpents (1796) and A Continuation of an Account of Indian Serpents (1801). McDiarmid et al. (1999) are among those who favor the original misspelling, citing Article 32c (ii) of the International Code of Zoological Nomenclature. Others, such as Zhao and Adler (1993) favor russellii.[5]

Etymology edit

The species is named after Patrick Russell (1726–1805),[6] a Scottish herpetologist who first described many of India's snakes, and the name of the genus is from the Hindi word[specify] meaning "that lies hid", or "the lurker".[7]

In English, common names of D. russelii include Russell's viper,[4][8][9][10] chain viper,[8][10] Indian Russell's viper,[11][12] common Russell's viper,[13] seven pacer,[14] chain snake, and scissors snake.[15]

Description edit

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.[4]

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 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.[4] The fangs attain a length of 16.5 mm (0.65 in) in the average specimen.[16]

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.[4]

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.[4]

Russell's viper grows to a maximum body and tail length of 166 cm (65 in) and averages about 120 cm (47 in) in mainland Asia. On islands, it is slightly shorter on average.[4] It is more slender than most vipers.[17] The following dimensions for a "fair-sized adult specimen" were reported in 1937:[18]

  • Total length 1.24 m (4 ft 1 in)
  • Length of tail 430 mm (17 in)
  • Girth 150 mm (6 in)
  • Width of head 51 mm (2 in)
  • Length of head 51 mm (2 in)

Distribution and habitat edit

 
 
Russell's viper from India

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.[3] The type locality is listed as "India". More specifically, this would be the Coromandel Coast, by inference of Russell (1796).[5]

Within its range, it can be common in some areas, but scarce in others.[17] In India, it is abundant in Punjab, very common along the West Coast and its hills, and 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 (scrub jungles), 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 (7,500–9,800 ft). Humid environments, such as marshes, swamps, and rain forests, are avoided.[4]

This species is often found in highly urbanized areas and settlements in the countryside, the attraction being the rodents commensal with man.[16] 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 (cobras and kraits).[4]

Behaviour and ecology edit

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.[4] 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.[4] 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.[4] These snakes are strong and may react violently to being picked up.[19] The bite may be a snap, or they may hang on for many seconds.[16]

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.[20][21] 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.[22]

Reproduction edit

Russell's viper is ovoviviparous.[17] 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,[4] although fewer offspring may occur, as few as one.[16] The reported maximum is 75[23] in a single litter. At birth, juveniles are 215–260 mm (8.5–10.2 in) in total length. The minimum total length for a gravid female is about 100 cm (39 in). 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.[4]

Prey edit

 
Russell's viper hunting

Russell's viper feeds primarily on rodents, although it will also eat small reptiles, land crabs, scorpions, and other arthropods. Juveniles are crepuscular, feeding on lizards and foraging actively. As they grow and become adults, they begin to specialize in rodents. Indeed, the presence of rodents and lizards is the main reason they are attracted to human habitation.[4] Juveniles are known to be cannibalistic.[16]

Mimicry edit

 
The rough-scaled sand boa Eryx conicus possibly mimics the appearance of Russell's viper

Some herpetologists believe, because D. russelii is so successful as a species and has such a fearful reputation within its natural environment, another snake has come to mimic its appearance. Superficially, the rough-scaled sand boa Eryx conicus has a color pattern that often looks like that of D. russelii, though it is completely harmless.[4][18]

Venom edit

Venom of this species is delivered by means of solenoglyphous dentition.[24] 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 (31 in), the venom yield ranged from 8 to 79 mg (mean 45 mg).[4]

The LD50 in mice, which is used as a possible indicator of snake venom toxicity, is: 0.133 mg/kg intravenous,[25] 0.40 mg/kg intraperitoneal,[26] about 0.75 mg/kg subcutaneous.[27] 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.[4] 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 (I.P) route, 0.75 mg/kg/subcutaneous (S.C) route and 0.3 mg/kg through intravenous (I.V) route.[28]

Symptoms edit

Envenomation symptoms begin with pain at the site of the bite, immediately followed by swelling of the affected extremity. Bleeding is a common symptom, especially from the gums and in the urine, and sputum may show signs of blood within 20 minutes after the bite. The blood pressure drops, and the heart rate falls. Blistering occurs at the site of the bite, developing along the affected limb in severe cases. Necrosis is usually superficial and limited to the muscles near the bite, but may be severe in extreme cases. Vomiting and facial swelling occur in about one-third of all cases.[4] Kidney failure (renal failure) also occurs in approximately 25–30 percent of untreated bites. Severe disseminated intravascular coagulation also can occur in severe envenomations. Early medical treatment and early access to antivenom can prevent and drastically reduce the chance of developing the severe/potentially lethal complications.

Severe pain may last for 2–4 weeks. It may persist locally, depending on the level of tissue damage. Often, local swelling peaks within 48–72 hours, involving both the affected limb and the trunk. If swelling up to the trunk occurs within 1–2 hours, envenomation is likely to be massive. Discoloration may occur throughout the swollen area as red blood cells and plasma leak into muscle tissue.[15] Death from septicaemia or kidney, respiratory, or cardiac failure may ensue 1 to 14 days after the bite, or sometimes later.[16]

A study in The Lancet showed that out of a sample of people who survived bites by D. russelii, 29% suffered severe damage to their pituitary glands, which later caused hypopituitarism.[29] Other scientific studies support the hypothesis that D. russelii bites can cause hypopituitarism.[30][31]

Antivenom treatment edit

In India, the Haffkine Institute prepares a polyvalent antivenom that is used to treat bites from this species.[16] In late 2016, a new antivenom had been developed by the Costa Rican Clodomiro Picado Institute, and clinical trials were started in Sri Lanka.[32]

Clinical use edit

Because this venom is so effective at inducing thrombosis, it has been incorporated into an in vitro diagnostic test for blood clotting that is widely used in hospital laboratories. This test is often referred to as dilute Russell's viper venom time (dRVVT). The coagulant in the venom directly activates factor X, which turns prothrombin into thrombin in the presence of factor V and phospholipid. The venom is diluted to give a clotting time of 23 to 27 seconds and the phospholipid is reduced to make the test extremely sensitive to phospholipid. The dRVVT test is more sensitive than the aPTT test for the detection of lupus anticoagulant (an autoimmune disorder), because it is not influenced by deficiencies in clotting factors VIII, IX or XI.[33]

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 1 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 He added the native people called it katuka retula poda 2 Analysis of morphological and mitochondrial DNA data shows that the eastern subspecies of D russelii should be considered a separate species Daboia siamensis 3 A number of other subspecies may be encountered in literature 4 including D s formosensis Maki 1931 found in Thailand considered a synonym of D siamensis D s limitis Mertens 1927 found in Indonesia considered a synonym of D siamensis D r pulchella Gray 1842 found in Sri Lanka considered a synonym of D russelii D r nordicus Deraniyagala 1945 found in northern India considered a synonym of D russelii The correct spelling of the species D russelii has been and still is a matter of debate Shaw and Nodder 1797 in their account of the species Coluber russelii named it after Patrick Russell but apparently misspelled his name using only one L instead of two Russell 1727 1805 was the author of An Account of Indian Serpents 1796 and A Continuation of an Account of Indian Serpents 1801 McDiarmid et al 1999 are among those who favor the original misspelling citing Article 32c ii of the International Code of Zoological Nomenclature Others such as Zhao and Adler 1993 favor russellii 5 Etymology editThe species is named after Patrick Russell 1726 1805 6 a Scottish herpetologist who first described many of India s snakes and the name of the genus is from the Hindi word specify meaning that lies hid or the lurker 7 In English common names of D russelii include Russell s viper 4 8 9 10 chain viper 8 10 Indian Russell s viper 11 12 common Russell s viper 13 seven pacer 14 chain snake and scissors snake 15 Description edit nbsp Head of the Russell s viper nbsp Large fangs nbsp Russell s viper in Pune ZooThe 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 4 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 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 4 The fangs attain a length of 16 5 mm 0 65 in in the average specimen 16 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 4 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 4 Russell s viper grows to a maximum body and tail length of 166 cm 65 in and averages about 120 cm 47 in in mainland Asia On islands it is slightly shorter on average 4 It is more slender than most vipers 17 The following dimensions for a fair sized adult specimen were reported in 1937 18 Total length 1 24 m 4 ft 1 in Length of tail 430 mm 17 in Girth 150 mm 6 in Width of head 51 mm 2 in Length of head 51 mm 2 in Distribution and habitat edit nbsp nbsp Russell s viper from India 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 3 The type locality is listed as India More specifically this would be the Coromandel Coast by inference of Russell 1796 5 Within its range it can be common in some areas but scarce in others 17 In India it is abundant in Punjab very common along the West Coast and its hills and 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 scrub jungles 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 7 500 9 800 ft Humid environments such as marshes swamps and rain forests are avoided 4 This species is often found in highly urbanized areas and settlements in the countryside the attraction being the rodents commensal with man 16 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 cobras and kraits 4 Behaviour and ecology editRussell 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 4 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 4 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 4 These snakes are strong and may react violently to being picked up 19 The bite may be a snap or they may hang on for many seconds 16 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 20 21 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 22 Reproduction edit Russell s viper is ovoviviparous 17 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 4 although fewer offspring may occur as few as one 16 The reported maximum is 75 23 in a single litter At birth juveniles are 215 260 mm 8 5 10 2 in in total length The minimum total length for a gravid female is about 100 cm 39 in 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 4 Prey edit nbsp Russell s viper huntingRussell s viper feeds primarily on rodents although it will also eat small reptiles land crabs scorpions and other arthropods Juveniles are crepuscular feeding on lizards and foraging actively As they grow and become adults they begin to specialize in rodents Indeed the presence of rodents and lizards is the main reason they are attracted to human habitation 4 Juveniles are known to be cannibalistic 16 Mimicry edit nbsp The rough scaled sand boa Eryx conicus possibly mimics the appearance of Russell s viperSome herpetologists believe because D russelii is so successful as a species and has such a fearful reputation within its natural environment another snake has come to mimic its appearance Superficially the rough scaled sand boa Eryx conicus has a color pattern that often looks like that of D russelii though it is completely harmless 4 18 Venom editVenom of this species is delivered by means of solenoglyphous dentition 24 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 31 in the venom yield ranged from 8 to 79 mg mean 45 mg 4 The LD50 in mice which is used as a possible indicator of snake venom toxicity is 0 133 mg kg intravenous 25 0 40 mg kg intraperitoneal 26 about 0 75 mg kg subcutaneous 27 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 4 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 I P route 0 75 mg kg subcutaneous S C route and 0 3 mg kg through intravenous I V route 28 Symptoms edit Envenomation symptoms begin with pain at the site of the bite immediately followed by swelling of the affected extremity Bleeding is a common symptom especially from the gums and in the urine and sputum may show signs of blood within 20 minutes after the bite The blood pressure drops and the heart rate falls Blistering occurs at the site of the bite developing along the affected limb in severe cases Necrosis is usually superficial and limited to the muscles near the bite but may be severe in extreme cases Vomiting and facial swelling occur in about one third of all cases 4 Kidney failure renal failure also occurs in approximately 25 30 percent of untreated bites Severe disseminated intravascular coagulation also can occur in severe envenomations Early medical treatment and early access to antivenom can prevent and drastically reduce the chance of developing the severe potentially lethal complications Severe pain may last for 2 4 weeks It may persist locally depending on the level of tissue damage Often local swelling peaks within 48 72 hours involving both the affected limb and the trunk If swelling up to the trunk occurs within 1 2 hours envenomation is likely to be massive Discoloration may occur throughout the swollen area as red blood cells and plasma leak into muscle tissue 15 Death from septicaemia or kidney respiratory or cardiac failure may ensue 1 to 14 days after the bite or sometimes later 16 A study in The Lancet showed that out of a sample of people who survived bites by D russelii 29 suffered severe damage to their pituitary glands which later caused hypopituitarism 29 Other scientific studies support the hypothesis that D russelii bites can cause hypopituitarism 30 31 Antivenom treatment edit In India the Haffkine Institute prepares a polyvalent antivenom that is used to treat bites from this species 16 In late 2016 a new antivenom had been developed by the Costa Rican Clodomiro Picado Institute and clinical trials were started in Sri Lanka 32 Clinical use edit Because this venom is so effective at inducing thrombosis it has been incorporated into an in vitro diagnostic test for blood clotting that is widely used in hospital laboratories This test is often referred to as dilute Russell s viper venom time dRVVT The coagulant in the venom directly activates factor X which turns prothrombin into thrombin in the presence of factor V and phospholipid The venom is diluted to give a clotting time of 23 to 27 seconds and the phospholipid is reduced to make the test extremely sensitive to phospholipid The dRVVT test is more sensitive than the aPTT test for the detection of lupus anticoagulant an autoimmune disorder because it is not influenced by deficiencies in clotting factors VIII IX or XI 33 References edit Shaw George 1797 The Russelian Snake The Naturalist s Miscellany
