Sound spider,,: feet listen.

The spider used to listen to the sound leg spider sound.

Spiders can't understand human speech. Spiders are non-auditory, humans, and most other vertebrates.

Both can use eardrums.

Come listen and convert sonic pressure into brain signals. But spiders are using their webs as extended auditory arrays to catch sounds, which may warn the spider in advance of impending prey or predators.

Arrival. Studies have shown that spiders can "outsource" their hearing to cobwebs.

Habits of spidersMost spiders eat insects, some spiders will choose to eat small animals, generally spiders live in grass or under the eaves, often to the wind and light of the place to build a web. The main reason is that there will be a lot of insects passing through such a location, so that a lot of insects can be netted as food to supplement nutrition.

If a spider lives in the soil, a trap will open at the entrance of the hole to prey on insects that pass through the hole. If it is a funnel spider, the webs are all funnel webs, and as long as the webs are landed, they will vibrate.

One thing to mention is that spiders don't have ears.

So they won't have hearing.

All perceptions are through vibrations, such as the vibration of the air, the vibration of the earth, etc., there are many fine hairs on the feet of spiders, all of which are connected to the true nerve endings, and they are very sensitive to external vibrations.

Experiment name: "Do spiders hear sounds with their feet".

Experimental tools: a table, a knife, a spider.

Experiment 1: Place the spider on the table and yell "crawl" and the spider crawls forward.

Experiment 2: Use a knife to cut off all the spider's feet, put them on the table, and yelled "crawl", but the spider did not crawl.

Conclusion: Spiders listen to sounds with their feet.

Grace !Because the hair on its legs can feel the sound waves!

The so-called cry of the spider is the sound of rubbing the limbs of the crow when it is in danger, and the small spider is relatively small and the spider generally does not make this sound back. The real spider call is a high-frequency wave sound made by spiders when mating, which is inaudible to humans, and it is estimated that your dog may hear it

Zhang Siyuan, what's wrong, I'm done.

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.

Smaller spiders generally don't make sounds.

Spiders make sounds similar to "hissing", but the sound does not come from the spider's mouth, but like crickets, the sound** is the rest of the body. The spider's voice is most likely from its chelicerae, which are its fangs.

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.
