The definition of venomous tongue is a snake that can cause damage to the human body, and is generally divided into nerve venomous snakes, hemorrhagic venomous snakes and hemorrhagic nerve mixed venomous snakes.

The kind that bites you will die is a poisonous snake.

Venomous snakes are hereditary.

Generally, the venomous snake snake is innate, that is to say, whether the snake is poisonous or not is inherited from birth. The venom of the snake is produced by the glands that produce toxins under the snake's teeth, which are equivalent to the salivary glands of people, when they are threatened, the snake will bite the threat and something, and then the glands containing the venom begin to contract and discharge the toxin, and then further transported to the top of the tooth through the venom tube at the back of the tooth, and then inject it into the body of the bitten object to cause poisoning.

Generally, the venom secreted by snakes is equivalent to the digestive juice of animals, which is a mixture of toxic proteases and polypeptides, and heating can destroy the activity of the venom and make the venom lose its toxicity. Generally, the toxin-producing glands of venomous snakes are separate organs, not connected to the body organs of other snakes, and its body has a special immune system for its own venom, which perfectly explains why poisonous snakes will not be poisoned to death after absorbing their own venom.

The habits of snakes

Snakes are ectotherms, and their activities are closely related to the outside temperature, and the temperature reaches more than 18 degrees before they come out to move. In the south, the peak incidence of snake bites is usually from May to October. Especially in the hot and humid rain or the early sunny days after the rain, snakes often come out of the burrow.

In addition, there have been many floods at the turn of spring and summer in recent years, and the floods will inundate a large area of snake caves, which will also cause an increase in homeless snakes on land. Therefore, in summer, special attention should be paid to snake prevention before the rain, after the rain, and after the flood.

There is a certain pattern of diurnal activity of snakes, different species of snakes, and different activity rules, cobras, king cobras are active during the day, silver krait is active at night, and pit vipers are active during the day and at night. Snake bites are also mainly concentrated at 9-15 o'clock during the day and 18-22 o'clock at night. In addition, pit vipers are very sensitive to heat sources and have the habit of fighting fires, so they should wear long pants when walking at night, and avoid poisonous snake bites when lighting up with bright fires.

When camping, the tent zipper should be completely closed.

Most venomous snakes grow and develop more slowly than non-venomous snakes. It takes at least 2 years for venomous snakes to reach sexual maturity; Some fast-growing non-venomous snakes take just over a year to reach sexual maturity. It takes 2 to 3 years for a viper to reach maturity due to artificial over-extraction.

As we all know, snake venom is the digestive substance of poisonous snakes, which plays a role in promoting digestion, if the poison is collected frequently without moderation, it will inevitably lead to loss of appetite, indigestion, and serious stomatitis, so that the snake's normal predation and swallowing are blocked, which directly affects its growth and development. In a sense, artificially bred poisonous snakes are far behind non-venomous snakes, and they are not as fast as their growth and development, which is related to the "snake-loving" behavior of venomous snakes.

The difference between venomous snakes and non-venomous snakes.

Venomous snakes generally have a large head and a thin neck, a triangular head, a short and abruptly taper tail, and a relatively bright body surface pattern.

Non-venomous snakes generally have a blunt garden shape, a thin neck, a slender tail, and many inconspicuous body surface patterns.

The most fundamental difference between venomous snakes and non-venomous snakes is that the teeth of venomous snakes are single-row, and the tooth marks of non-venomous snakes are double-rowed.

The head of a venomous snake is generally triangular in shape.
