Why isn't it poisonous? What to do if you have bitten a person? Habitats of the tiger snake

The snake is one of the types of snakes that do not belong to the poisonous group. However, the bite of a snake that attacks a person when its life is threatened causes the development of a complex symptomatic picture.

Most often, the reason for a snake attack is the inappropriate behavior of the person pestering the snake - touching the reptile with a stick, trying to anger it in every possible way.

Sometimes it happens that, being in the habitat of reptiles - a pond, in swamps, a person does not look at his feet, stepping on a snake. Children are often bitten when they try to grab the snake, and in defense of itself, the reptile bites its offenders.

The only species of snake that is poisonous is the tiger snake; its bite can cause death without timely assistance.

The habitat of the tiger species is Korea, Japan.

Snakes are fairly peaceful snakes. They calmly coexist with people, will never attack first, preferring to crawl away or pretend to be dead. The only thing a snake can do to scare you is its feces, which it releases when threatened, which is characterized by a foul odor. Often this reptile releases its feces onto humans.

Warning that it may attack, the snake begins to hiss loudly, sticking out its tongue. If you leave her alone at this moment, the matter will be limited to such threats.

The poisonous tiger snake behaves in the same way, with the only difference that when it bites, it releases a toxic substance, which is a rather dangerous toxin for the human body.

Many people are often confused harmless snake with a viper, the bite of which provokes severe symptoms. If a snake has bitten and the victim is not sure what it was, it is recommended to take the victim to the hospital as quickly as possible and describe to the doctor exactly what the reptile that attacked the patient looked like.

Having seen on my summer cottage or a snake in the water, many begin to panic, thinking that they are about to become a victim of a poisonous bite. There are a number of characteristics that can be used to distinguish snakes from other species of reptiles. These include the following:

• oval head shape;
• shiny scales;
• presence of yellow or orange spots on the head;
• round eye shape.

Despite the presence of teeth oral cavity, there are no bags of poison there. The bite of this type of snake does not pose a danger to humans; the only thing that can happen is that if the wound after the attack is not properly treated, an infection can get into it, causing an extensive inflammatory process. Most often you can encounter a snake during the day, since the reptile sleeps at night.

The main source of food is frogs and small lizards.

This type of snake got its name due to its color similar to the fur of a tiger. Along its entire length, the reptile has muted orange stripes. Lives in China, Japan and Korea. At its core, it is not an aggressive type of snake, but if it feels threatened, it will attack. The degree of poisoning depends on which teeth the reptile used to bite the skin.

If the skin is pierced with short teeth of the front row, there will not be any particular intoxication, since in in this case a secret that contains toxic substances, does not show through. As in the case of a simple snake attack, the only thing that can happen is that the wound from the teeth gets infected.

If it is grabbed by the teeth located in the back jaw, the poison begins to rapidly enter the wound along the grooves from the teeth. Intoxication in this case will be very strong and without treatment will lead to death.

Symptomatic picture with poisonous bite tiger snake is the same as in most cases of attacks by venomous snakes.

First of all, the central one suffers nervous system and vegetative functions of the body. Paralysis gradually appears, leading to disruption of the functioning of the heart muscle, causing heart failure, sudden cardiac arrest and death.

The only treatment method is the introduction of a special serum.

If she is not in the hospital, complex drug therapy is carried out to remove the toxin from the body. Anti-inflammatory and painkillers are prescribed medicines, drugs to relieve spasms and normalize the functioning of all internal organs and systems.

In order to avoid becoming a victim of a tiger snake attack, you must follow simple safety measures while in the habitat of these reptiles - look carefully around, do not touch the snake crawling past, do not put your hands in a pile of stones or holes.

Symptoms of a bite that are insignificant in intensity can only be observed if a person has a tendency to allergic reactions.

Clinical manifestations of a snake bite:

• teeth marks on the skin in the form of several reddish dots;
• slight bleeding from the wound site, which, in most cases, goes away on its own, without any assistance;
• itching on the skin, similar to a mosquito bite;
• minor swelling (optional symptom).

People who have been victims of snake attacks compare the feeling of a bite to the feeling of a cat digging into your skin.

A more serious clinical picture is observed when attacked by a tiger snake. A person shows signs of poisoning:

In most cases, complex symptoms after a tiger snake bite appear in children and people prone to allergic reactions.

In this case, the victim must be taken to medical institution, since the development of complications is possible, cases of death are known to medicine.

If bitten, the victim, despite the fact that he was the victim of a non-venomous attack, needs first aid. First of all, you need to take the following actions:

1. Wash the wound thoroughly under running water using soap, preferably laundry soap.
2. Treat the wound with antiseptic drugs - hydrogen peroxide, Chlorhexidine.
3. If swelling develops, you need to apply a cold object to the skin. This can be ice or a piece of frozen product, previously wrapped in a towel, so that there is no frostbite of the soft tissues, which provokes necrosis. If there is no ice, you can use a towel soaked in cold water, it must be constantly dipped again.

After this, the wound can be lubricated with iodine. In the future, if a person works in the garden and constantly gets his hands dirty, the wound can be covered with a bandage soaked in antiseptic and healing ointments or creams.

Contact for medical care necessary in case of symptoms such as increased body temperature, severe fatigue and lethargy, extensive swelling at the site of the bite, redness of the skin. These signs indicate that the wound has become infected and must be treated with antibiotics prescribed only by a doctor. In other cases medical treatment not required.

How not to behave when bitten by a snake? It is strictly forbidden to cauterize the wound site. Firstly, this is an absolutely useless procedure that will only cause harm by causing a painful burn on the body. Secondly, there is no longer any poison that would need to be pulled out of the wound.

The incision will cause severe swelling and redness.

6. 9 effective advice about that

The tiger snake, in terms of the structure of the skull and the location of the poisonous teeth, belongs to the posterior sulcatated snakes; it’s just that the large teeth are located in the depths of the oral cavity.

External signs of a tiger snake

The body structure is similar to common snake and reaches a length of 1 meter. In the back of the head, under the skin, 10-19 pairs of nucho-dorsal glands are visible, hidden under a small skin ridge.

The scales are covered with longitudinal ribs, which are clearly defined. Big eyes with a round pupil. The last two teeth in the upper jaw are large, curved backwards, separated from the remaining teeth by a small gap. The color of the tiger snake's skin is distinguished by its variegated shades.

This is one of the most beautiful reptiles from the collection of Russian herpetofauna. The upperparts are bright green, sometimes dark green or dark olive in color, grading to light brown or almost black tones. On the main background there are black stripes located across them, which are divided into lateral and dorsal spots. The edges of the scales located in front of the body are colored intensely red or orange-red color. This feature of the skin is characteristic only of adult individuals. The sides of the head are decorated with 2 noticeable black spots. The first is on the temple, and the second is in the shape of a triangle, extending through the lower edge of the eye to the very upper jaw.

Peculiarities of tiger snake behavior

Tiger snakes spend the winter in abandoned burrows of mouse-like rodents or in voids underground, forming aggregations of several hundred snakes.

They react to danger by raising vertically top part bodies. This flat-necked defensive posture is similar to that of a cobra opening its hood.

In addition, tiger snakes make body throws towards the enemy, accompanying these body movements with a loud hiss. The caustic substance produced by the nucho-dorsal glands irritates the predator’s oral cavity, and it immediately abandons its prey. However, tiger snakes are not such harmless snakes and can inflict bites themselves, but the short teeth usually do not penetrate too deeply, the poison does not enter the blood. Posterior grooved snakes seem to chew the victim. But if the skin is scratched by the long back teeth, hidden deep in the oral cavity, the poison enters the bloodstream and causes severe poisoning of the body.

Keeping a tiger snake in a terrarium

The conditions for breeding tiger snakes in captivity are the same, as are the features of breeding common snakes. The temperature in the terrarium is maintained within 28-30 degrees. Reptiles reproduce well in captivity, possibly without wintering, although experts recommend not disturbing the natural cycle of snakes. Mating usually occurs in February or March, but may occur later if wintering is prolonged.

After 48 days, the female lays 8-22 eggs; they differ in size 2.7-3.5 X 1.6-2.0 mm and weigh twenty grams. Embryos in eggs develop at a temperature of 27-30 degrees and ninety percent humidity. The incubation period is 34-38 days. Young snakes have a body length of 15-20 cm. A week after birth, the supper offspring molt. Young snakes grow quickly, and at the age of one and a half years they are able to give birth.

Poisonous properties of the tiger snake

Tiger snakes do not have real glands with poison, that is, developed from the upper jaw. A poisonous properties reptiles are determined by the Duvernois gland, which has evolved into salivary gland.

But, despite the obvious difference, the poisonous secretion has not lost its properties. Although the strength of the poison is less pronounced than that of other poisonous reptiles: copperheads, cobras, vipers. Therefore, the tiger snake is called a “conditionally poisonous” snake, meaning that its poisonous teeth are hidden deep inside the mouth.

Therefore, if you had to deal with a snake, you need to behave calmly and not make sudden movements.

You definitely shouldn't do this:

• trying to pick up a snake;
• catch it with a stick;
• run after a reptile;
• throw stones at the snake.

It will definitely bite if you step on it. Such snakes live near ponds in tall grass. Therefore, it is better to walk in such areas in high rubber boots.

Snake bite is a fairly common problem among tourists and nature lovers. This snake prefers rain forests, marshy areas. The reptile itself is quite peaceful and is not the first to attack humans. But if disturbed, it can bite the offender. Whether a snake has venom depends on its variety, of which there are about a dozen.

Important! It's easy to see when a snake is about to bite. She begins to hiss and sticks out her tongue. In this case, you need to move away from the snake, then it will not attack.

Why is it dangerous for humans?

Most of these snakes belong to the family of non-venomous reptiles. The only exception is the tiger snake, living in Korea and Japan, on Far East Russia. Its teeth contain a poisonous substance used to paralyze insects and rodents. For humans, the snake's venom is less dangerous, but in susceptible people it can be fatal. The tiger snake got its name because of its specific color - along its entire length there are stripes of dark orange color, reminiscent of the skin of a tiger.

When bitten by a poisonous snake, it is of great importance what teeth the reptile used to pierce the human skin. Largest quantity The poison is contained in the teeth located deep in the jaw.

Simple non-venomous snakes live throughout Europe and Asia, excluding the polar regions. In Russia this is one of the most common reptiles.

• it already has an oval head, the viper has a triangular head;
• the scales of the viper are matte and dark, while the snake has a bright color;
• the most noticeable difference between a non-venomous snake and a poisonous one is the presence of two bright yellow or orange spots on the first’s head;
• it already reaches a meter in length, and the viper is no more than 70 cm;
• The pupils of a poisonous snake are vertical, reminiscent of a cat’s, while those of a non-venomous snake are round

A frightened snake secretes a yellow liquid with an intense unpleasant odor from special glands - this is its way of defense. There are many varieties of snakes, but none of them, except the brindle, have dangerous poison. Some representatives of the colubrid family do not even know how to bite. This includes the water snake. Outwardly, it is very similar to a viper, but is not at all poisonous, and instead of teeth it has plates for grinding food.

Symptoms and consequences of a snake bite

Manifestations of a grass snake bite look like this:

• teeth marks in the form of paired dots;
• slight bleeding from the wound;
• swelling of the skin at the site of injury.

A person may experience mild pain and itching at the site of the bite. These sensations are caused by tissue irritation by snake saliva, which is ejected from the teeth when the skin is pierced. In a healthy person, symptoms after a bite last 2-3 days, then disappear.

• weakness;
• difficulty breathing;
• headache;

• after a while nausea and vomiting appear;
• then blood appears in the vomit;
• A hemorrhagic rash forms on the legs and arms.

If a person does not know which snake has bitten him - poisonous or not, or whether it was a completely different reptile - he must immediately seek medical help, describing appearance snakes.

Providing first aid for a snake bite

After an attack by a snake, even a non-venomous one, a person requires first aid. It consists of carrying out the following activities:
