Why do snakes always spit out snake letters? Is the snake that spits out the letter a poisonous snak

The snake is using the snake letter to collect information about the smell of the surroundings.

The snake's tongue has a slender and forked tip of the tongue, which is always swallowing and spitting, commonly known as "Nobuko".

Not only is the snake's sense of sight and hearing very poor, but its sense of taste has also deteriorated, and it does not know what the food tastes like when it is eaten in the mouth.

However, the snake's sense of smell is quite developed and can distinguish many kinds of smells, but its olfactory organ is not the nose, but the long, thin tongue with a forked tip.

The snake's tongue is its olfactory organ.

When the snake sticks out its tongue, it gets some material particles, and after it is retracted, the tongue stretches out into a pair of small cavities above the front of the mouth, this part is called the nasal aid, which is the snake's "odor analysis room", which is not connected with the outside world and cannot directly produce a sense of smell, but it can achieve the olfactory function with the help of the snake's tongue, so as to judge the environmental conditions in which it is located.

The serpent spits out letters.

Snake letter is used to catch the smell, **there is prey, **there is danger,**there is water, and the flow direction of release is all known by snake letter. So always spit snake letters.

Snakes rely primarily on their tongues to get information. When the snake is trying to catch prey or is active, the snake will frequently stick out its tongue and vibrate rapidly to detect as much as possible the surrounding environment.

Snakes have sensors on their tongues, which are used to capture heat and sense the presence of prey.

The snake that spits out the letter is not necessarily a poisonous snake.

The snake's tongue is a very special organ unique to snakes, reptiles.

Lizards. Classes are also available. Snakes are particularly sensitive to the letter of the snake, they are the snake's olfactory organ, and at the same time it is a way to detect the outside world.

Any healthy snake always keeps swallowing its tongue! But the illness makes the sedan snake will not vomit or occasionally vomit, which is also a judgment pet snake.

Whether it is healthy or not.

The tongue of an animal is usually the organ of taste, but the tongue of a snake is very special and is the organ of smell. It has no taste buds on it, so it cannot distinguish sour, sweet, bitter, and salty tastes. The snake's tongue often sticks out of its mouth, and can stick to or dissolve various chemical molecules in the air on the moist surface of the tongue before judging what has happened.

The reason why the snake does this frequent movement shouting

In fact, they are collecting chemical molecules, which can also be said to be material particles in the surrounding air, and the snake's letter is moist, and when the tongue sticks out of the mouth, it will adsorb tiny molecules that cannot be seen visually on the tongue, and then retract and shake up and down.

In fact, this is because the tongue stretches into a pair of small cavities above the front of the mouth, this part is called a nasal aid, which is not connected to the outside world and cannot directly produce a sense of smell, but it can achieve olfactory function with the help of the snake's tongue.

Snakes' nasal aids are composed of many sensory cells, which can identify chemicals in particles through the synthesis and analysis of chemical information through the olfactory center. After judgment, the snake can accurately capture its prey. When a snake bitten animal escapes, the snake can use its retractable tongue and sensitive nasal aid to locate and track until it finds its target again.

The snake spits out the letter and gathers information.
