There is a snake that can dance and what a snake is

It's a cobra, and if you play a flute in front of it, it will dance. But the cobra does not dance because it hears the sound of the flute, but when it sees the movement of the flute.

Latin scientific name. naja

English name. cobra

Cobra is the Portuguese name for "snake", which originated in Latin. When Portuguese navigators arrived in Africa and South Asia in the 16th century, they discovered the cobra and named it "snake with hood" or "hood-snake", and the name spread to Spanish, French, English, and other European languages. The name "snake with hood" or "hood-snake" comes from the fact that the cobra looks like a "snake with a hood".

Chinese name. Cobra.

Cobra is a general term for some snake species in the genus Cobra or Cobraidae. The origin of the name of the cobra should be that after the appearance of glasses in modern times in the seventeenth and eighteenth centuries, it became the official name. Because when its neck expands, it will show a pair of beautiful black and white spots on its back, which looks like a glass-like pattern, hence the name cobra.

There is no unified name before the official naming, most of the snakes in Chinese history do not have special names, and the folk have many names for cobras (of course, different species of cobras), such as: mountain snakes, big flat-necked snakes, flat-necked snakes, blowing snakes, mountain markers, mountain winds, mountain storms, rice shovel heads, rice spoons (when they are excited or angry, the head will be raised and the neck expands to be flattened, like a rice spoon), five poisonous snakes, bat snakes, swell-necked snakes, swell-necked snakes, large swelling necks, fan-headed winds, large flat-headed winds, etc.

In most species, the ribs in the neck can expand to form a hood. Although this hood is characteristic of cobras, not all species are closely related.

Cobras are found in the area from southern Africa through southern Asia to the islands of Southeast Asia. Within their range, snake charmers like to use different species of snakes, and snake charmers will scare the snake into a defensive posture with the front of its body lifted off the ground. The snake reacts to the snake charmer's movements in a swaying manner, and it may also react to the snake charmer's **; The snake charmer knows how to dodge the snake's slower attack movements, and may have pulled out the snake's fangs.

The fangs are short, located at the front of the mouth, and have a groove attached to them that secretes venom. The venom of cobras is usually neurotoxin, which destroys the nervous system of prey. Cobras feed mainly on small vertebrates and other snakes.

Cobras rely on nerve venom to kill their prey. Neurological venom can block neuromuscular conduction, resulting in fatal muscle paralysis.

The bite of cobras, especially the larger species, can be fatal, depending on the amount of venom injected, and the neurotoxins in the venom can affect breathing; Although antivenom is effective, it must also be injected as soon as possible after being bitten. In South and Southeast Asia, thousands of related deaths occur each year.

The natural predators of the cobra include the meerkat and some birds of prey: the meerkat eats the head of the cobra directly with its speed, but the cobra will also bite the mongoose during the fight, so the meerkat can wake up after a few hours of fainting, but a small number will also be devoured by the cobra.

The elongated neck of the black snake also has this function.

Let's start making a paper snake that turns.

The first step is to prepare the ingredients: paper snakes, cotton thread, candles and matches. How does a paper snake do it?

First, find a blank piece of paper, draw a thread on the white paper, draw a head in the middle, and then cut the paper snake along the line. Cut slightly wider on the periphery and narrower at the middle. So that the paper snake is done.

The second step is to pierce a small hole in the middle of the head of the paper snake and put on the cotton thread.

The third step is to light the candle with a match and hang the paper snake above the flame of the candle, and after a while, you can see the paper snake slowly spinning, as if dancing a light dance, slowly, slowly, the rhythm of the paper snake is getting faster and faster, as if dancing a beautiful dance.

It's so strange, how can a paper snake spin? How does this work? With this question in mind, I turned on the computer, and ah! The paper snake spins because the flame of the candle generates heat, causing the air to rise and push the paper snake to spin.

What is the principle of the paper snake dancing while turning? When a lit candle heats the air above it, the space heats up and widens the distance between the air molecules, and the heated air becomes lighter and rises, while the surrounding cold air rushes to its place. The hot air pulls the paper snake as it rises, causing the paper snake to dance.

Hot air rises and cold air falls, and the repeated circulation of this air is what causes the wind.

In addition to the ring dance, Sachs also gave a very unique insight into the design of other forms of group dance, and when talking about the "serpentine dance", he believes that the dance is derived from the ring dance, which is a ring dance that is separated from the circle form. The "serpentine dance" is expressed in many places as the action of "crossing the labyrinth". Sachs noted

The essence of the labyrinth is action. The labyrinth building itself has little meaning, it only makes sense when people walk through the labyrinth. This movement through the labyrinth premeditates the form of the 'serpentine dance', but the 'serpentine dance' does not pre-design anything for the labyrinthine building."
