How to prove that spiders hear on their feet

Put a spider on the table, then yell at the spider "crawl" and the spider scares away! Then he took the spider back, put it on the table, and cut off all the spider's feet. Then he yelled at the spider and shouted "crawl", and the spider didn't move!

This proves that the spider's sense of hearing is on the feet. Hehe, that's a joke above. Because spiders rely on webs to catch their prey, their sensory organs are mostly concentrated on their feet.

But spiders don't have hearing organs, it's just a joke.

Spiders do not have external ears, and they rely on the sensitive hair on their feet to perceive their surroundings. These hairs can help spiders sense vibrations and sounds in the air, as well as recognize vibrations on the ground.

Therefore, to prove that the spider's hearing is on the feet, the following experiments can be done:

1.Place a spider on the table and yell at it "crawl" to observe its reaction.

2.Grab the spider, cut off its feet, and yell at it to "crawl" to see how it reacts.

If the spider has a significant response in the first experiment and no response in the second experiment, then it can be proved that the spider's hearing is on the feet.

No, the spider has bristles on its feet, it has a sense of touch, it vibrates the air when it makes a sound, it can feel it, it's not hearing, it's touch.

Spiders are both beneficial and harmful to humans, but in terms of their contribution, they are mostly beneficial insects. For example, in farmland, spiders prey mostly on pests of crops. At the same time, in many traditional Chinese medicines, there are records of using spiders in medicine, so it is of great significance to protect and use spiders.

In particular, the protection of rice field spiders has three major benefits: first, it effectively stabilizes the balance of biological populations; the second is to reduce the residual toxicity of chemical pesticides in rice and ensure the safety of humans and animals; Third, the production cost is reduced, and the production and income can be increased. Therefore, in the prevention and control of crop diseases and pests, we advocate the use of high-efficiency and low-toxicity pesticides, carry out biological control, and protect natural enemies.

Spiders are diverse, widely distributed, adaptable, it can live or build webs on the surface of the soil, in the soil, on trees, among grass, under rocks, burrows, water's edge, low-lying land, bushes, moss, inside and outside houses, or inhabit freshwater (such as water spiders), coastal lake zones (such as lake spiders). In short, there are traces of spiders in the water, land and air.

1. Spiders have no sense of hearing, and the best sense of a spider is that it is not accurate to say that it is touch, but it should be a vibration sense. Although there are similarities between the sensation of vibration and the sense of touch, the difference is also obvious. Only in the sense of vibration, spiders are the most sensitive, unmatched by other animals.

2. Although the spider's vision is poor, it has a very developed vibration sense, as long as the insect falls on the web, a small pull, it can feel, and according to the signal ** sensitive vibration feeling to make up for the defects of the spider's weak visual ability.

3. Spiders rely on vibration to prey and mate, no wonder their vibration sense is particularly sensitive, which is incomparable to other animals.

The auditory organ is also an organ that senses vibrations... The human ear perceives the vibration of the air, the inner ear of the fish perceives the vibration of the liquid, and the vibration of the solid and the gas at the same time. Arthropods are very sensitive to touch and have specialized auditory organs.

Crickets and locusts have separate antennae and auditory apparatus that support tactile and auditory functions, respectively. Many arthropods have ears that are unimaginable to ordinary people, not because they do not have hearing organs...

Spiders have no sense of hearing.

It is not accurate to say that the most excellent sensation of a spider is the sense of touch, but the sensation of vibration. Although the vibration sensation is similar to the tactile sensation, the difference is also obvious.

It is at least more accurate to say "vibrational sensation" than "touch", because the sense of touch includes the sensation of temperature, the sensation of softness, the sensation of roughness, and so on, and in these senses, spiders are not particularly sensitive. Only in terms of vibrational sensation, the blind land spider is the most sensitive, which is incomparable to other animals.

Although the spider's vision is poor, it has a very developed vibration sense, as long as the insect falls on the net, a small pull, it can feel, and according to the signal**, quickly and accurately find the insect, feast, a good meal. Therefore, the sensitive vibration sensation makes up for the lack of spider vision.

Female and male spiders also communicate in this way when they reproduce:

The male spider stops at the edge of the female's web, and he first pulls the web rhythmically, and uses his front steps to play the silk strings in a certain rhythm. At first, the female spider rushed over the mill like any other insect, and the male carefully retreated to the outside of the web. When the female spider retreats to the web**, the male spider flicks the web again.

This is repeated several times, when the female spider receives this signal, no longer rushes out, but sits quietly in the web ** waiting, the male spider keeps moving the net to send out a vibration signal, and crawls towards the female spider. Complete the mating with the female spider. This way of interfering with spiders is really amazing.
