A trip to the forest for mushrooms or just a walk in nature can bring a lot of unpleasant moments to a person (see). Often in the forests and fields, people encounter snakes - ancient reptiles that have lived on earth for millions of years. There are quite a few varieties of snakes. Some are considered dangerous to humans (see), others deliver a lot of unpleasant sensations (including pain), others do not pose any threat to people's lives at all. It is very important to be able to distinguish dangerous snakes from harmless ones, so many people have the question: is it poisonous?

Snakes are often confused with vipers, and this ignorance of the variety of snakes becomes dangerous for humans (see). Much more muscular and larger than a viper, its skin is covered with scales. On the head of the snake are two yellow spots, shaped like "ears". It is very rare to find a reptile without these identification marks. The body is mostly uniform in color, brown or gray-green. Vipers have a diamond-shaped pattern on their bodies. The pupil of the eye of the snake is always round, the pupil of the poisonous viper is vertical and constricted.

How do snakes live?

Snakes live everywhere, these snakes can be found in forests, in fields, meadows, near ponds and reservoirs. The length of the snake is about a meter, females are larger than males, reach a length of 1.5 meters, however, there were also large individuals. The largest already reached a length of about 3 meters. Reptiles feed mainly on small amphibians (frogs, lizards, newts). Juveniles prey on insects, tadpoles and small fish.

The snake tracks down its prey, and then, with the help of a throw, attacks the prey. Sometimes snakes start chasing frogs. They grab their future food by the head or hind legs, and then swallow it whole. The snake can attack small warm-blooded animals, such as rodents or chicks. They live in burrows under rotten trees in a pile of foliage.

They breed from May to June. In winter, the snake hibernates. With the advent of spring, it wakes up, throws off its old skin (sheds) and begins to look for partners for mating. Molting occurs in different ways: sometimes the skin of the snake comes off the whole body (stocking). But it happens that the old stratum corneum falls off in pieces. In this case, snakes rub their bodies against stones, trees, trying to get rid of old skin. A fertilized female lays her eggs in a warm and damp place (heap with rotten foliage, compost, rotten stumps). After 5-6 weeks, small serpents hatch from the eggs.

On warm sunny days, the snake loves to bask in the sun, so it can be found in the grass on lawns and fields. In nature, these snakes have a lot of enemies. Often snakes become prey for storks, serpent eagles, kites. Of the terrestrial predators, martens, raccoon dogs, minks and foxes are considered dangerous for snakes. In most cases, rats destroy snake clutches by eating their eggs and newly hatched snakes.

The tiger already lives in Primorsky Krai, Khabarovsk, Korea and Japan. Since its poison is considered low-toxic, it does not harm a person.

Its teeth contain a poisonous substance used to paralyze insects and rodents. For humans, the poison is less dangerous, but in susceptible people it can be fatal. Brindle already got its name because of the specific color - along its entire length there are stripes of dark orange color, reminiscent of the skin of a tiger.

Of great importance when biting a poisonous snake is what teeth the reptile pierced the human skin with. The greatest amount of poison is contained in the teeth located deep in the jaw.

Simple non-poisonous snakes live throughout Europe and Asia, excluding the polar regions. In Russia, this is one of the most common reptiles. The snake prefers to settle closer to humans, choosing wet areas. But you can often see a grass snake basking in the sun. Representatives of the already-shaped family feed on small insects, frogs.

• the scales of the viper are dull 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 head of the former;
• in length it already reaches a meter, and a viper - no more than 70 cm;
• the pupils of a poisonous snake are vertical, reminiscent of a cat, in a non-venomous snake they are round

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

Symptoms and consequences of a snake bite

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

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

• difficulty breathing;
• headache;
• muscle twitches;

• fever;
• severe fatigue;
• severe swelling of the tissues at the site of the bite;

Within a few days, you need to treat the bite site with antiseptics, change the bandage. If necessary, the damaged skin is lubricated with healing ointments.

Treatment for a viper bite requires the introduction of a special serum, and this must be done as quickly as possible.

How to protect yourself from bites?

Answering the question whether snakes bite or not, they do not attack a person first, for no reason, but they can only bite as a defense. Therefore, it is enough just not to tease the reptile, and then it will not cause harm. If a person walks in places with tall grass or in swamps, he may accidentally step on this snake and then it will bite on the leg, defending itself.
