Spectacled snake (Indian cobra). Indian cobra. Lifestyle and habitat of the Indian cobra Naya snake

The spectacled snake or Indian cobra belongs to the family of asps and is included in the genus of true cobras. The reptile lives in Central Asia. These are India, Nepal, Pakistan, Bangladesh, Sri Lanka. The snake can be found in impenetrable jungles and open areas. It rises to a height of 2 thousand meters above sea level. It is often found on the outskirts of cities and in farms, as it feeds on rats and mice.

The head is round, the eyes are small, the pupil is round. Poisonous fangs are located on the upper jaw. The length of the reptile reaches 1.7-1.9 meters. The maximum length reaches 2.4 meters. A notable feature of the snake is that when in danger, it raises a third of its body vertically and spreads its upper cervical ribs to the sides. At the same time, the neck expands significantly and becomes flat. And on the stretched skin at the back, a pattern clearly appears. In its outline it resembles glasses. Hence the name “spectacled”.

The body color of the reptile is quite variable and depends on its habitat. The main background varies from light gray to brown. It even comes in black. The belly is light with a slight yellowish tint. Young snakes have dark stripes located transversely on their bodies. They disappear with age.

Reproduction and lifespan

This species is oviparous. Eggs are laid between April and July. To do this, abandoned termite mounds or rodent burrows are selected. There are from 10 to 30 eggs in a clutch. Incubation period lasts 60-70 days. The hatched snakes reach a length of 20-30 cm. They are already poisonous and immediately begin independent life. Sexual maturity occurs in the 3rd year of life. IN wildlife The spectacled snake lives up to 20 years.

Behavior and nutrition

Indian cobra has a very strong poison that paralyzes the muscles of the victim. In humans, symptoms of poisoning appear within 15 minutes to 2 hours. It all depends on what part of the body the poisonous fangs are embedded in. But death occurs only in 6 cases out of 1000. This is explained by the fact that, when defending itself, the snake does not always release poison. In most cases, it is limited to a normal bite. The reptile feeds on rodents, toads, frogs, birds and other types of snakes.

The formidable reptile is very popular among magicians and fakirs. It is representatives of this species that they use in their performances. Spectacled snake kept in a wicker basket, and when people gather around, the lid is removed and poisonous reptile rises from it. There is an opinion that spellcasters pull out poisonous fangs to protect themselves. But that's not true. In place of the removed fangs, new ones grow very quickly, and poison is produced in any case. In addition, after the performance, spectators often demand to show their fangs. If they are not there, the fakir will be ridiculed.

These reptiles are kept in captivity. In principle, there is nothing wrong with this, since the Indian cobra never bites unless necessary. If you do not show aggression towards her, then she will behave calmly. A snake lives in a terrarium. The temperature in it is maintained at 28-30 degrees. Humidity corresponds to 60-80%. The diet consists of rodents, frogs, toads and lizards. This species is highly respected in India. In Hindu mythology, this reptile is considered a powerful deity. The fearsome reptile is worshiped during the Nag Panchami festival.

Spectacled cobra (Naja naja (LINNAEUS, 1758))- the taxonomic parent of almost all Asian cobras; previously, many of the independent species were just subspecies of the spectacled cobra; there are no examples of a more striking restructuring of the species than the history of studying the systematics of the spectacled cobra. Back in the 19th century there was only one species -Naja najawith 10 subspecies, four of which were found in India:Naja naja naja- Indian subspecies with glasses on the hood;Naja naja kaouthia- cobras with one ring on the hood;Naja naja oxiana(Central Asian cobra);Naja naja sagittifera(Andaman cobra). Thanks to the Indian herpetologist Deraniyagala (1945, 1960, 1961), all four subspecies acquired independent status, and new subspecies were identified forNaja naja: Naja naja indusiin the north-west of India, they are “characterized” by the absence of ordinary teeth on the maxillary bone, although normally there should be one;Naja naja madrasiensisin the south, it was believed that their poisonous teeth were morphologically sufficiently developed for spitting;Naja naja gangeticain northeast India, a subspecies without any basis, even in the original article;Naja naja bombaya- central India, identified from a single find, distinguished by the absence of “cuneate” scales;Naja naja karachiensis- southern Pakisat and adjacent territories of India. For the nominative formNaja naja najaconsidered the population of spectacled cobras from Sri Lanka, but all of Deraniyagala’s arguments were not weighty enough, and many of his works were subsequently ignored by his colleagues. In 1984, a temporary subspecies appearedNaja naja polyocellata, which even Deraniyagala called only a special Sri Lankan variation, but not a subspecies, was later decided as such.


Now everything is different, but there are studies of cladists, according to which one of the most famous snakes is more basal than other species. All this is very important in fact, especially for poisonous snakes, as it turns out, each species has its own toxicology, all differ greatly in the effect and strength of the poison, the fight against the consequences of bites varies depending on the type of cobra. Quite a few people died from the generalization of all Asian cobras into one species; it is enough to mix up the serums. Studying the taxonomy of venomous snakes leads to optimization of the process of producing antivenom serums.

LivesSpectacled cobra in the following countries: Pakistan, India (in most of the country), Myanmar, Sri Lanka, Bangladesh, Nepal, Bhutan, eastern Afghanistan. In India, one of the four deadliest snakes, including the epha (Echis carinatus), bungar (Bungarus caeruleus) and chain viper (Daboia russeli), we can safely say that this is one of the most dangerous snakes in the world, although not as poisonous as taipans, up to 10,000 deaths from the venom of spectacled cobras are recorded per year.



This is a large snake, often reaching two meters (record holders from Sri Lanka), usual sizes 100-150 cm (newborns 25-30 cm), very powerful body, easy to distinguish from other types of cobras by the spectacled pattern on a very large hood, however, This sign is very variable. The standard option is when there are two black spots (their width is two scales) on the back with a light edging, but there may be more spots, or they may be completely absent. The color can also be different, there are yellow, gray, reddish and completely black snakes with light white specks, there are also natural melanists, sometimes they are classified as a separate subspeciesNaja naja karachiensis- Pakistani black cobra, last time under this name was published in 2013, quite recently, people still remember the works of the famous Indian herpetologist, by the way, in the Pakistani population of spectacled cobras, the babies are colored gray, and the hood does not always have glasses from birth. Why are Pakistani cobras not a separate subspecies? In fact, according to the signs, everything is in order, if you wish, you can calculate the pattern in the number of scales, the color is special, more than anything, but there is not enough isolation from other spectacled cobras, so it all depends on herpetologists, some elevate this point to a fundamental one, others ignore it, It is worth noting that not all subspecies of snakes in mandatory The presence of isolation is characteristic; hybrids at the border of populations are simply recognized. Let's return to the characteristicsNaja naja. The population from Sri Lanka can have up to 20 transverse black stripes on the belly, normally there should be 1-5, the very position of the large “throat” collar is also variable, the error can reach up to 10 scales. The number of rows of dorsal scales in spectacled cobras is very variable, it all depends on the population, in the northwest the number of rows is less, and there are populations with such a large number of dorsal rows that no other Asian cobra has. They can be distinguished from the closest monocle cobras by the presence of one small triangular “inter-labial” (cuneate) scale above the fifth lower labial, or between the fourth and fifth, and again, just don’t get angry, however, there are spectacled cobras without these scales, I wrote above about the subspeciesNaja naja bombaya, it is not recognized, because many spectacled cobras with a “cuneate” were subsequently found from its habitats; the trait is attributed to the limits of individual variability. The range of spectacled cobras overlaps with many other former subspecies, the differences are always minimal, most often taxonomists are guided by the pattern on the hood, the color on the ventral side and the isolation of some species from others, because the number of abdominal, dorsal, and caudal scales overlaps greatly for different species, given the variability of the spectacled cobra cobras



The length of poisonous teeth can reach 7.5 mm, spectacled cobras have the longest teeth relative to body size among cobras throughout Asia, in addition to poisonous fangs there are also non-venomous teeth, spectacled cobras usually have one non-venomous tooth on the maxillary bone, but sometimes this rule is not works, and there is no dependence on certain populations, everything is within the limits of individual variability, chaotic, for this reason they refused to distinguish subspeciesNaja naja indusi And Naja naja bombaya. In 1% of cobras, two teeth were found on the maxillary bone.

An interesting detail: almost all cobras can spit venom, to varying degrees, of course, butNaja naja And Naja oxianaThere are no devices for this at all.

For the above reasons, studying the behavior of spectacled cobras, their lifestyle, diet, the action of poison and much more turned out to be difficult, because in old publications there is not always a description of the morphology and there are no high-quality images of the objects of study, one has to guess about which of the 10 species of the “spectacled cobra complex” “we were talking, but the types are completely different. Now imagine, the most famous snake in the world because incredible number The mistakes of morphologists and herpetologists were not studied until 1998!

Spectacled cobras have spread so widely for a reason; they can occupy a variety of niches, they are found everywhere, from tropical forests to rice fields, in arid places, they are often seen near settlements, move well on water and climb well at low heights. In terms of diet, everything is also very universal, most of it consists of rats and other small rodents, then equal number followed by tailless amphibians, lizards (even monitor lizards), snakes, including poisonous snakes, such as ephas. They have time to learn everything and go everywhere thanks to round-the-clock activity; they prefer evening and night time, but can be active during the day.

From April to July, spectacled cobras lay eggs, there can be up to 45 eggs in a clutch, usually less, females remain to guard the nest until the babies hatch, incubation lasts 48-69 days. An interesting fact: hybrids of monocle cobras and spectacled cobras are characterized by the protection of clutches in pairs; males also participate in this process.


Everyone knows how cobras defend themselves, the spectacled ones are better than all others in this regard, and all thanks to the hood of record sizes, relative to the body, of course. If threatened, snakes take a characteristic stance on a third of the body, hiss loudly and make throws towards the irritant, it is extremely rare that everything comes to a bite, usually these are head blows, if bites do occur, they are not always fatal; when defending, spectacled cobras use little poison, and sometimes it is not injected at all. I remind you, this type cannot spit, all publications on this subject were due to confusion with other species - former subspeciesNaja naja.



Iin spectacled cobras it is complex, includes a postsynaptic neurotoxin and a cardiotoxin; when bitten, muscle paralysis occurs, breathing stops, and the heartbeat is disrupted. Hyaluronidase in cobra venom is capable of increasing the permeability of tissues by reducing the viscosity of the mucopolysaccharides included in their composition, this leads to necrosis and accelerated spread of the venom throughout the victim’s body. Symptoms begin within the first 15 minutes, and in special cases appear after two hours. For mice LD50 ("venom strength") is 0.45 mg/kg - 0.80 mg/kg, I remind you that the lower this value, the stronger the poison, for the taipan the same figure is around 0.03 mg/kg, for Blanding's boiga 2.88 mg/kg. On average, a spectacled cobra injects 169-250 mg of venom per bite. If serum was used during this time, there is a high probability of complete recovery after a full bite, the probability of death is 15-20%.



I don’t recommend keeping it in captivity, but if it so happens that there is a cobra, it’s worth considering the following. Young individuals can be kept in small plastic containers per 10 liters, for adult individuals a large terrarium is required, of sufficient size so that the snake can move in it, so that shelter can be installed (with a moist substrate inside, such as moss), a drinking bowl and so that there is the necessary temperature gradient, from 24 to 28 background, in point up to 33 (day 12 hours), at night you can drop to 22-24, wintering 16-20 degrees for two months a year, the photoperiod is reduced. To be honest, adult spectacled cobras are successfully kept and bred in plastic containers with a volume of about 100 liters; no wintering or playing with light is carried out. Of course good ventilation is necessary. Suitable substrates include mulch, shavings, coconut substrate, coconut chips, pine chips, paper, newspaper, and napkins. Lighting doesn't matter. Humidity is 60%; spraying is necessary only during molting. The diet in captivity can consist of only rats, do not overdo it, obesity is very dangerous for all snakes.



Synonyms for spectacled cobra in different areas of its range: nag, murkan, naya, nagu pamu, nagara havu, naga pambu, nalla pambu, fetigom, gohra.

In the future, the consolidation of the Albino morph of the spectacled cobra, hypomelanists and other interesting variations are already known, everything is still ahead, there is every chance to catch up with the monocle.


Always remember about special safety precautions when working with venomous snakes; all information on this subject is presented on our forum.

Thank you very much for your attention))) There will be more to come

Indian cobra(from the Latin Naja naja) is a poisonous scaly snake from the family of asps, a genus of true cobras. This snake has a body that tapers to a tail, 1.5-2 meters long, covered with scales.

Like all other types of cobras, the Indian cobra has a hood that opens when this adder is excited. The hood is a kind of extension of the body, which arises due to the expanding ribs under the influence of special muscles.

The color palette of the cobra's body is quite variegated, but the main ones are shades of yellow, brown-gray, and often sandy colors. Closer to the head there is a clearly defined pattern, reminiscent of pince-nez or glasses along the contour, which is why it is called Indian spectacled cobra.

Scientists divide the Indian cobra into several main subspecies:

• blind cobra (from Latin Naja naja coeca);
• monocle cobra (from Latin Naja naja kaouthia);
• spitting indian cobra(from Latin Naja naja sputatrix);
• Taiwanese cobra (from Latin Naja naja atra);
• Central Asian cobra (from the Latin Naja naja oxiana).

In addition to those mentioned above, there are several other very few subspecies. Often the Indian spectacled cobra is also attributed to the species Indian king cobra, but it's a slightly different look that has big sizes and some other differences, although very similar in appearance.

Pictured is an Indian spitting cobra

The Indian cobra, depending on the subspecies, lives in Africa, almost throughout Asia and, of course, on the Indian continent. In the territory former USSR these cobras are widespread in the open spaces modern countries: Turkmenistan, Uzbekistan and Tajikistan - a subspecies of the Central Asian cobra lives here.

Chooses to live in various areas from the jungle to the mountains. On rocky terrain it lives in crevices and various burrows. In China, people often settle in rice fields.

Character and lifestyle of the Indian cobra

This type of poisonous snake is not at all afraid of humans and can often settle near his home or in fields cultivated for crops. Often Indian cobra found in abandoned, dilapidated buildings.

This type of cobra never just attacks people unless it sees danger and aggression from them; it bites, injecting poison, only in defense, and then, most often, it is not the cobra itself that serves as a deterrent, but its ominous hiss.

When making the first throw, also called a deception, the Indian cobra does not produce a poisonous bite, but simply makes a blow with its head, as if warning that the next throw could be fatal.

In the photo there is an Indian cobra naya

In practice, if the snake managed to inject venom during the bite, then the bitten person has little chance of survival. One gram of Indian cobra venom can kill more than a hundred medium-sized dogs.

Spitting cobra what is the name of the subspecies of Indian cobra, generally rarely bites. The method of its protection is based on the special structure of the dental canals through which the poison is injected.

These channels are located not at the bottom of the teeth, but in their vertical plane, and when danger appears in the form of a predator, this snake sprays poison on it, at a distance of up to two meters, aiming at the eyes. If the poison gets into the eye shell it leads to a burn of the cornea and the animal loses clarity of vision; if the poison is not quickly washed off, then further complete blindness is possible.

It should be noted that the Indian cobra has short teeth, unlike other venomous snakes, and are quite fragile, which often leads to their chipping and breaking off, but new teeth very quickly appear to replace damaged teeth.

In India there are many cobras living in terrariums with humans. People train this type of snake using the sounds of wind instruments, and enjoy performing various performances with their participation.

There are many videos and photo of Indian cobra with a man who, playing the pipe, makes this adder rise up on its tail, opening its hood and, as it were, dancing to the music playing.

Indians have a positive attitude towards this type of snake, considering them a national treasure. This people has many beliefs and epics associated with the Indian cobra. On other continents, this adder is also quite famous.

One of the most famous stories about the Indian cobra is the fairy tale famous writer Rudyard Kipling called "Rikki-Tikki-Tavi". It tells about the confrontation between a fearless little one and an Indian cobra.

Indian cobra nutrition

The Indian cobra, like most snakes, feeds on small mammals, mainly rodents and birds, as well as amphibious frogs and toads. They often destroy bird nests by eating eggs and chicks. Other species of reptiles are also used for food, including smaller poisonous snakes.

Large Indian cobra can easily swallow a large rat or a small one at a time. For a long time For up to two weeks, a cobra can do without water, but having found a source, it drinks quite a lot, storing liquid for the future.

The Indian cobra hunts at different times of the day and night, depending on its habitat. It can search for prey on the ground, in water bodies and even in high vegetation. Outwardly clumsy, a snake of this type excels at crawling through trees and swimming in water, looking for food.

Reproduction and lifespan of Indian cobra

Sexual maturity in Indian cobras occurs in the third year of life. The breeding season takes place in winter in January and February. After 3-3.5 months, the female snake lays eggs in the nest.

The clutch averages 10-20 eggs. This type of cobra does not incubate eggs, but after laying them they are constantly close to the nest, protecting their future offspring from external enemies.

After two months, the baby snakes begin to hatch. Newborn babies, freed from the shell, can easily move independently and quickly leave their parents.

Considering that they are born immediately poisonous, these snakes do not need special care, since they can protect themselves even from large animals. The lifespan of the Indian cobra varies from 20 to 30 years, depending on its habitat and the availability of sufficient food in these places.

Cobra is the common name for different types of poisonous snakes from the family Aspidae (lat. Elapidae), not united by a common taxonomic unit. Most of these reptiles belong to the genus True cobras (lat. Naja).

The name “cobra” appeared in the 16th century, when during the “history of the great geographical discoveries“When the Portuguese moved to India, they first met the spectacled snake. They named her Cobra de Capello(“snake in a hat”). Following their example, British travelers and merchants began to call all “hooded” snakes cobras.

Cobra - description and photo. What does a cobra look like?

The length of the cobra depends on the age of the reptile. These snakes grow throughout their lives, and the longer they exist, the larger they become.

From the recorded records it is known that the smallest cobra is the Mozambican cobra (lat. Najamossambica), the average length of an adult reptile is 0.9–1.05 m, with a maximum length of up to 1.54 m. The largest cobra in the world is the king cobra (lat. Ophiophagus hannah), reaching a maximum size of 5.85 meters and a weight of more than 12 kg.

In a calm state, cobras are difficult to distinguish from other snakes. Being irritated, they take a characteristic pose: they raise them high above the ground top part body, expand the cervical and partially torso regions, creating the illusion of volume.

Thanks to elastic muscles 8 pairs of reptile ribs expand and form the so-called hood, which distinguishes cobras from other snakes. By the way, it is thanks to the hood that cobras scare away the enemy.

The coloration of cobras is adaptive. Desert species are sandy-yellow in color, arboreal ones are greenish in color, and inhabitants of places overgrown with plants are variegated. In the tropics, where the most plants are found different colors, live vibrant views: coral cobra (lat. Aspidelaps lubricus) and red spitting cobra (lat. Naja pallida). Spectacled snake (lat. Naja naja) is decorated with light circles on the dorsal side of the upper body. A characteristic feature of cobras is the presence of more or less pronounced transverse dark stripes, more noticeable on the neck.

The cobra's head is rounded in front, flat on top, covered with scutes that are absent on the cheekbones. Having no neck part, it smoothly passes into the body. The scales on the back of the reptile are smooth, and the ventral side is covered with greatly expanded light scutes.

The cobra's eyes are dark, small and unblinking, covered with a thin transparent film formed when the eyelids grow together. They are well protected from dust and moisture loss, but because of this coating, the cobra's vision is not very clear. The film of the eyes comes off along with the skin during molting.

In diurnal snakes, like cobras, the pupil of the eyes is round.

The upper jaw of the snake is armed with fairly large (6 mm Central Asian species), sharp, poisonous tubular teeth. The cobra's teeth are not long enough, and therefore the reptiles are forced to hold the victim tightly with them in order to inflict several bites at once. According to the structure of the venomous apparatus, representatives of the aspid family belong to the anterior grooved (proteroglyphic) snakes. Their poisonous teeth are located in the front part of the narrow upper jaw, a “seam” is noticeable on their outer surface, and the poison flows not along the groove on the outside, but inside the tooth along the poison-conducting channel. The teeth sit motionless in the jawbone. Due to their convenient location and perfect venom-producing apparatus, a cobra bite is deadly.

Behind these teeth, poisonous snakes have others that replace the main ones when they are damaged. There are a total of 3-5 pairs of teeth on the upper jaw of cobras. They are sharp, thin, curved back and are not intended for tearing and chewing prey. Cobras swallow their prey whole.

The most important sensory organ for snakes is the chemical analyzer (Jacobson's organ, which has two openings on the upper palate of the reptile) in combination with the tongue. The cobra's long, narrow tongue, forked at the end, protrudes, flutters in the air or palpates nearby objects and again hides in the semicircular notch of the upper jaw, leading to Jacobson's organ. This is how an animal analyzes chemical composition everything nearby or at a distance, recognizes prey, even if a small proportion of its substances is present in the air. This organ is very sensitive, with its help the snake quickly and accurately finds a victim, a mating partner or water supplies.

Cobras have a well-developed sense of smell. Their nostrils are located on the sides of the front of the skull. They do not have an external ear, and in the understanding to which we are accustomed, cobras are deaf, since they do not perceive air vibrations. But due to the development of the inner ear, they detect even the slightest vibrations in the ground. Snakes do not react to human screams, but they perfectly notice his stomping.

Cobras molt 4 to 6 times a year and grow throughout their lives. Molting lasts about 10 days. At this time, snakes hide in shelters, as their body becomes vulnerable.

Where do cobras live?

Snakes with a “hood” are inhabitants of the Old World (Asia, Africa). They are extremely thermophilic and cannot exist where snow cover forms. The exception is the Central Asian cobra: in the north, its habitat includes parts of Turkmenistan, Uzbekistan and Tajikistan. In Africa, cobras are found throughout the continent. Cobras also live in South, Western, Eastern and Central Asia, on the Philippine and Sunda Islands. They prefer arid places: savannas, deserts, semi-deserts. Less common in tropical forests, in the mountains up to an altitude of 2400 m, in river valleys. Cobras do not live in Russia.

Cobras are very agile snakes; they can crawl through trees and swim. They are active mainly during the day, but in deserts they lead night look life. The average speed of a cobra is 6 km per hour. She will not be able to catch up with a fleeing person, but this is a hypothetical statement, since cobras never chase people. A person can catch up with a snake quite easily.

What does a cobra eat?

Most cobras are predators; they eat amphibians (,), birds (ground-nesting small passerines, nightjars), reptiles (more often than others, less often), mammals (rodents), and fish. They can eat bird eggs. Some species do not refuse carrion.

Cobra breeding

Cobras breed once a year. Depending on the climate zone, in which they live, their breeding season can begin in both the spring and winter months. For example, the king cobra has a mating period in January-February. Males fight for the female, but do not bite each other. A male cobra can even eat a female if she was fertilized by someone before him. Mating is preceded by courtship, during which the male makes sure that the female is not going to dine on him (in the king cobra).

Mating of reptiles continues for an hour. After 1-3 months most of Cobras (oviparous) lay eggs, the number of which varies depending on the species and can be either 8 or 80 pieces. Only one species, the collared cobra, is viviparous. She gives birth to up to 60 live cubs at a time.

Ovoviviparous cobras lay eggs in nests they build from leaves and branches (Indian and king cobras), in hollows, and in crevices between stones. The diameter of a king cobra's nest can reach 5 meters; the snake builds it on a hill so that rainwater does not flood the nest. The temperature of 24-26 degrees Celsius required for the development of juveniles is maintained by the optimal volume of rotting leaves.

In almost all species of cobras, usually the female, and sometimes the male, guards the future offspring until they hatch. Immediately before the babies appear, the parents crawl away from them so that after a long hunger strike they themselves do not eat them.

The emerging cubs are already completely similar to the representatives of their genus and species, and are also poisonous. The threat pose in cobras is an innate phenomenon, and snakes that have just emerged from eggs freeze at the sight of danger in the same way as adults. On the first day, the babies feed on the remains of egg yolks preserved after hatching. Due to their size, at first small cobras hunt only small prey, often content with insects.

How long do cobras live?

The lifespan of cobras in nature has not been established, but there are known cases of some species living up to 29 years. In terrariums they live up to 14-26 years.

Classification of cobras

There are 37 species of snakes in the world that can extend their necks into a hood. All of them belong to the Aspidae family, but to its different genera. Below is the classification of cobras according to the website reptile-database.org (dated 03/21/2018):

Types of cobras, names and photographs

• King cobra (hamadryad) (lat. Ophiophagus hannah ) is the largest venomous snake in the world. Many herpetologists believe that the concept of king cobra includes several subspecies, since this reptile is very widespread. The snake lives in Southeast and South Asia. Inhabits India south of the Himalayas, southern part China to Hainan Island, Bhutan, Indonesia, Myanmar, Nepal, Bangladesh, Cambodia, Pakistan, Singapore, Laos, Thailand, Vietnam, Malaysia, Philippines. Found in forests with dense undergrowth and grass cover, it rarely crawls near human habitation. The average size of an adult king cobra is 3-4 meters, with some individuals growing up to 5.85 meters in length. Average weight A king cobra weighs 6 kilograms, but large specimens can weigh more than 12 kg. The adult snake has a dark olive or brown body with or without light oblique rings, and a dark olive to black tail. Juveniles are usually dark brown or black with white or yellowish transverse stripes. The snake's belly is light cream or yellowish in color. A distinctive feature of the king cobra is the additional 6 scutes on the back of the head, which differ in color.

The king cobra spends most of its time on the ground, although it successfully climbs trees and swims deftly. It is active during the day and usually hunts its own kind, eating both poisonous and non-venomous snakes(cobras, boigs, kraits, kuffiyehs, snakes), sometimes the cobra eats its cubs. Only occasionally, for variety, can he snack on a lizard.

This species is oviparous. First, the female builds a “nest” by raking leaves and branches into a heap with the front part of her body. There she lays her eggs and covers them with rotting leaves on top. She herself is placed nearby, jealously guarding the future offspring from anyone who inadvertently dares to approach him. Sometimes the father also participates in security. Cubs are born 50 cm in size, with shiny skin, as if tied with a yellow-white ribbon.

The venom of the king cobra is very strong: they even die from its bite. A person bitten by a king cobra can die within 30 minutes. The reptile actively warns approaching enemies by emitting a high-pitched whistling hiss, adopting a “cobra pose”, but at the same time rising 1 meter higher than other cobras and not swaying from side to side (royally). If a person who notices the snake’s threatening pose freezes in place, the cobra will calm down and crawl away. The snake is impatient and not attentive only if someone is near its nest.

• Spectacled snake (Indian cobra) (lat. Naja naja ) lives in Asian countries: Afghanistan, Pakistan, India, Sri Lanka, Bangladesh, Myanmar, Nepal, Bhutan, South China.

The length of the snake is from 1.5 to 2 m, weight reaches 5-6 kg. She has a head rounded at the front, without a noticeable cervical interception, passing into a body covered with smooth scales. The Indian cobra is quite brightly colored, although the color and pattern of populations living in different places can vary greatly. There are yellow-gray, black and brown individuals. The ventral part can be yellowish-brown or light gray. Young individuals are decorated with dark transverse stripes, which first fade with age and then disappear completely.

The distinctive feature of the Indian cobra is its white or milky drawing on the upper side of the body, which becomes noticeable only when the hood is opened, there are ring-shaped spots resembling eyes or glasses. This adaptation helps the cobra avoid being attacked by predators from behind.

• Central Asian cobra (lat. Naja oxiana) found in Tajikistan, Turkmenistan, Uzbekistan, Iran, Afghanistan, India, Pakistan, Kyrgyzstan. Hides among stones, in rodent burrows, in gorges, among sparse vegetation, near rivers, in the ruins of man-made buildings. It also lives in the depths of dry deserts.

This poisonous reptile reaches 1.8 meters in size and is distinguished by the absence of a pattern in the form of glasses on the dorsal side of the neck. The color of the dorsal part of the cobra varies from dark brown to light beige, the belly of the snake is yellowish with dark transverse stripes, narrower and brighter in young individuals. As the reptile matures, the stripes on the abdominal part are replaced by spots or specks. The species does not form large groups, and even in spring it is not possible to detect more than 2-3 individuals in one area. In spring, under favorable conditions, Central Asian cobras hunt during the day. In hot areas they are noticeable only in cool mornings and evenings. In autumn they can be seen much less frequently, but at this time of year they are active during the day. The cobra hunts birds, amphibians, small rodents, and reptiles (lizards, boas, etc.). She also eats bird eggs. The mating season of the snake begins in the spring, and in July the cobra lays 8-12 eggs 35 mm long. In September, juveniles 30 cm in size emerge from them.

The venom of the Central Asian cobra has a pronounced neurotoxic effect. An animal bitten by it becomes lethargic, then develops convulsions and quickens breathing. Death occurs as a result of paralysis of the lungs. But a cobra rarely bites, only when in a desperate situation. At first, she always takes a warning, demonstrative pose, hisses and gives the attacker the opportunity to leave. Even if the attacker does not retreat, she first makes a false bite - she quickly rushes and hits the enemy with her muzzle with her mouth tightly closed. This way she protects her valuable teeth from possible breakage and saves the poison for real prey.

• Spitting Indian cobra (lat. Naja sputatrix) lives in Indonesia (on the Lesser Sunda Islands: Java, Bali, Sulawesi, Lombok, Sumbawa, Flores, Komodo, Alor, Lomblen).

She has a wide head with a cervical intercept, a short muzzle with large nostrils and rather large eyes. The body color is uniform - black, dark gray or brown. The hood is light on the ventral side. Average length snakes - 1.3 m, cobra weighs slightly less than 3 kg.

The snake throws poison towards the attacker at a distance of up to 2 meters, trying to get into his eyes. The poisonous teeth of a spitting cobra have a specific structure. The external opening of their venom-conducting channel is directed forward, not downward. The reptile injects venom using strong contractions of specialized muscles. The jet hits the target very accurately. The reptile uses this method of defense only for defense against large enemies. Cobra venom that gets into the eyes causes clouding of the outer membrane of the eye and in this way stops the attacker. If your eyes are not rinsed with water immediately, complete loss of vision may occur.

• Egyptian cobra, gaya, or real asp (lat. Naja haje) lives in northern Africa and the Arabian Peninsula (in Yemen). Lives in mountains, deserts, steppes and near human settlements.

A real adder grows up to 2.5 meters and weighs 3 kg; its expanded “hood” is much narrower than that of the Indian cobra. The color of the dorsal side of the cobra is uniform - dark brown, red-brown, gray-brown or light yellow, with a light, creamy ventral side. Several broad dark stripes on the neck become visible when the snake assumes a warning posture. Young reptiles are brighter and have patterns of wide light yellow and dark brown rings.

Gaia is active during the day, the cobra's diet consists of small mammals, reptiles, amphibians and birds. The snake can swim and climb trees.

• Black-necked (black-necked) cobra (lat. Naja nigricollis) known for the ability to accurately shoot poison into the eyes of an attacker. The snake lives in the southern tropical zone Africa - from Senegal to Somalia and to Angola in the southeast.

The body length reaches 2 meters, the weight of the cobra reaches 4 kg. Coloring ranges from light brown to dark brown, sometimes with indistinct transverse stripes. The neck and throat are black, often with a transverse white stripe.

When irritated, a cobra can shoot venom up to 28 times in a row, releasing a portion of 3.7 mg. It accurately hits its target, but sometimes confuses shiny objects with its eyes - trouser buckles, watch dials, etc. The venom of the black-necked cobra does not cause inflammation, but if it gets into the eyes, it will cause temporary loss of vision. By studying the process of releasing venom in this type of cobra, scientists found that during the contraction of special muscles, the entrance to the reptile’s trachea also closes. This ensures a directed flight of the jet, which is not displaced by the air flow.

The cobra hunts small rodents, lizards, reptiles and birds. Since it lives in a hot region of the planet, it is active more often at night, and during the day it hides in tree hollows, termite mounds, and animal burrows. This is an oviparous animal; a clutch can contain from 8 to 20 eggs.

• Black and white cobra (lat. Naja melanoleuca) lives in Central and West Africa: from Ethiopia and Somalia in the east to Senegal, Guinea and Gabon in the west, from Mozambique, Angola, Zambia and Zimbabwe in the south to Mali, Chad and Niger in the north. Lives in forests, savannas, and mountains up to an altitude of 2800 meters above sea level. Can climb trees.

The ventral side of the body of this cobra species is yellow with black stripes and spots scattered over it. irregular shape. Adults are dark brown or brown with a gray metallic sheen and a black tail. Young reptiles are dark-colored with light transverse thin stripes. The length of the cobra often reaches 2 meters; individuals of 2.7 m are less common.

The reptile does not spit poison. In nature, the snake lives for about 12 years, recorded and record time The lifespan of a cobra is 29 years. The reptile is active during the day and feeds on fish, rodents, amphibians, birds, monitor lizards and other lizards. Its venom ranks second in strength among African snakes after the venom of the Cape cobra. She lays up to 26 eggs in animal burrows and tree hollows. Juveniles 35-40 cm long appear after 55-70 days.

• Cape cobra (lat. Naja nivea) lives in Lesotho, Namibia, South Africa, Botswana. Prefers desert, steppe and mountain landscapes, often settling near bodies of water.

It is a venomous snake and often has a transverse brown stripe on the underside of its neck. The color of the cobra can be amber yellow, light yellow, bronze, brown, copper, solid or with spots. The length of its body varies from 1.2 to 1.5 m, although there are individuals measuring up to 1.8 m or more. In addition to live prey, it eats carrion. It hunts during the day, but on hot days it is active in the evenings; it can crawl into people’s homes in search of and. Its poison is considered the most powerful in Africa. The female lays up to 20 eggs.

• Ringed water cobra (lat. Naja annulata) is a poisonous animal with a small head and a dense body, up to 2.7 m long and weighing 3 kg. The average length of an adult reptile varies between 1.4 and 2.2 m. The dorsal side of the reptile is yellowish-brown, covered with transverse light stripes. Diving to a depth of 25 meters, she catches fish and eats mainly only them. Less commonly it feeds on frogs, toads and other amphibians. Can stay under water for up to 10 minutes.

The ringed water cobra lives in Cameroon, Gabon, Democratic Republic Congo, Republic of the Congo, Central African Republic, Tanzania, Equatorial Guinea, Rwanda, Burundi, Zambia, Angola. The snake's habitats include rivers and lakes, where it spends most of its time, as well as nearby areas: shores and savannas overgrown with bushes and trees.

• Collared cobra (lat. Hemachatus haemachatus) highlighted in separate genus thanks to some important distinctive features. Unlike other cobras, it does not have any other teeth behind its poisonous teeth. It's not very long snake, reaching a maximum of 1.5 m, with a dark brown or black dorsal part, along which intermittent oblique transverse stripes are scattered. Darker varieties of the reptile are often found, but the head and lower neck of this reptile are always completely black, and the belly has transverse black and yellowish-cream stripes. Almost completely black species always have a light stripe on the neck. The hood of this poisonous snake is quite narrow.

The collared cobra lives in South Africa (Zimbabwe, Lesotho, South Africa, Swaziland). Here, for its ability to spit venom, it was nicknamed “spui-slang” - a spitting snake.

• Monocled cobra (lat. Naja kaouthia) is an oviparous snake that is found in China, Cambodia, Myanmar, India, Thailand, Laos, Malaysia, Bhutan, Bangladesh, Vietnam, and is also believed to be found in Nepal. The reptile swims well, settles both on plains, in forests and fields, and in mountainous areas, creeps into pastures and rice plantations, can live near cities and villages. The animal is active both during the day and at night, but prefers to hunt at night.

On the hood of a poisonous snake there is only one light circle, and not two, like other spectacled snakes. The average length of the reptile is 1.2-1.5 m, the maximum length is 2.1 m. There are individuals with creamy-gray, yellow and black colors. The monocle cobra has a rather nervous and aggressive character.

• Siamese cobra (lat. Naja siamensis) lives in Vietnam, Thailand, Cambodia and Laos. According to some reports, it is also found in Myanmar. The reptile settles in lowlands, hills, plains and forests, sometimes approaching human habitation.

The average size of a poisonous snake is 1.2-1.3 m, the maximum is 1.6 m. Within the species, there is variability in the color of reptiles. In eastern Thailand, Siamese cobras are uniformly olive, greenish or light brown. In the center of the country there lives a population with contrasting longitudinal or transverse black and white coloring in the form of alternating stripes. In western Thailand, this type of cobra is black in color. The pattern on the hood is also somewhat different. It can be V-shaped or U-shaped.

The Siamese cobra is oviparous and active at night.

• South African shield cobra (lat. Aspidelaps lubricus) - inhabitant of the south of Angola, Namibia and the Cape Province of South Africa.

This is a venomous oviparous snake, 0.45 to 0.7 m long, with a rounded head covered in front with large triangular shields. The cobra's head is red with two black stripes, one of which runs from the nostrils to the top of the head, branching to the eyes, the other, transverse, crosses the first at neck level. The body of the cobra is pink, yellowish or orange color, intersected by transverse black rings.

The South African shield cobra is a nocturnal animal that lives in burrows or under rocks, preferring semi-deserts and sandy areas. The cobra's food is small vertebrates, mainly reptiles.

Indian cobra is a representative of the true cobra genus. This is a very poisonous snake. Every year more than 50 thousand people die from its bites in India alone, although there are many more cases of attacks. Some are saved by timely administered serum, others by the fact that the bite was “false.” The unpleasant proximity of reptiles and humans plays a big role in this, thanks to which attacks become commonplace.

The Indian cobra, or Naya, is divided into several subspecies, including

• blind;
• spitting Indian;
• monocle;
• Central Asian;
• Taiwanese.

Habitat

The spectacled cobra lives on African continent, not the territory of the Asian part of Eurasia. Its habitat includes Turkmenistan, Uzbekistan, Tajikistan and India. It inhabits both humid jungles and mountainous areas. In China, cobra can often be found in rice fields.

Description

The Indian cobra is a fairly large snake, with a body up to two meters long, covered with dense scales. Distinctive feature This type of snake has a hood, which the cobra opens in case of danger or excitement. The hood causes swelling of the body of the Indian cobra, formed as a result of the expansion of the ribs and intercostal muscles.

Indian cobras vary in color body surface. More often the scales are yellow, grayish-brown or sandy in color. Close to the head there is a pattern, the contours of which resemble glasses, for which the cobra is called a spectacled snake. Drawing performs protective function. When attacking it, it seems to the predator that the snake is looking directly at him, and not with his back turned.

Features of behavior

This type of reptile is not at all afraid of humans, so very often they inhabit places near human habitation, outbuildings or agricultural land. Often the Indian cobra can be seen in abandoned buildings. Indian cobras rarely attack first. If a person is not a source of danger for her and does not show aggression, the cobra will not attack, but will prefer to hide. All cases of attack are associated with the natural defense of the snake at a time of threat to life.

Basic diet reptiles consists of small rodents, birds, and amphibians. The snake can destroy bird nests and eat eggs and chicks. Near villages, the snake can prey on poultry, small animals, mice and rats. The large Indian cobra easily swallows a rat and a small hare. Snakes can go without water for a long time.

Depending on the region where they live, snakes of this species hunt in different time days. As a rule, they look for prey on the ground, in tall grass or in water, since this snake swims very well. When attacked, the spectacled snake takes a defensive stance, raising its upper body, spreading its hood, while emitting a loud hiss.

Most Indians know that the spectacled snake has a noble character and never doesn't attack first. The first throw of a snake is always deceptive: the snake does not inject poison, but strikes with its head, as if warning of its intentions. If the victim did receive the dose deadly poison, within half an hour alarming signs of poisoning will appear:

• severe dizziness,
• confusion,
• muscle weakness,
• impaired coordination of movements.
• severe vomiting.

After a few hours, paralysis of the heart muscle occurs and the person dies. The poison is very highly toxic. One gram of poison is enough to kill about a hundred small dogs.

An interesting subspecies is the spitting cobra, which almost never bites. Thanks to special structure she injects poison into her teeth. The canals are not located in the lower part of the tooth, but in the lateral surface . In case of danger she spits poison at a distance of up to two meters, trying to get into the victim’s eyes. This leads to damage to the cornea and loss of vision. Unlike other types of venomous snakes, the reptile's teeth are very brittle and fragile. When bitten, this leads to chipping and breaking off. New teeth grow very quickly.

Reproduction

In the third year of life, the Indian cobra reaches sexual maturity. The mating season of the spectacled snake falls in January and February. After three months, snakes lay 10-20 eggs. This species constantly guards the egg laying while being nearby.

After two months, the cubs appear, can move independently and leave the nest. Many species of spectacled snake in India are kept in terrariums near humans. They become participants in numerous performances for tourists.

Indian cobra is a species of snake that is considered a national treasure. A lot of legends and beliefs are associated with this snake. Rudyard Kipling's fairy tale "Rikki-Tikki-Tavi" about the confrontation between a small mongoose and a huge Indian cobra is known all over the world.

Many have heard or personally observed dancing spectacled snake to the tune of a snake charmer. This sight is incredibly dangerous if some measures are not taken. Therefore, many charmers remove snakes' teeth or sew up their mouths before performing. In fact, there are several people in the world who can work with poisonous snakes. These people know well the habits of snakes and what movements they can react to aggressively.
