Do spiders have a sense of hearing? Do spiders use their legs to hear sounds

There are auditors. The spider nervous system is similar to that of crustaceans, it is a cord-like nervous system, the ganglia are more concentrated, the brain is located above the esophagus, and a pair of nerve fibers form a peripharyngeal nerve ring, and there is an abdominal nerve chain. The central nervous system includes the brain (located in the head), the hypopharyngeal ganglia, and the ventral nerve cord, the sympathetic nervous system includes the frontal ganglia, the posterior cephalic ganglia and the bursal ganglia, and the sensory organs include eyes, antennae, auditory, taste, olfactory, thermosensor, etc.

There is also a peripheral nervous system.

Not really, but it has a sense of hearing, and the sense of touch is the most sensitive, and the spider immediately rushes over as soon as the worm sticks to the web...

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!

Spiders do not have a sense of hearing, but are particularly sensitive to vibrations from the outside world, and their responses to external shocks are perceived by their legs.

Spiders don't have a sense of hearing!His reflection ** their legs!They have a sensory organ on their legs that lets them know what's approaching.

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 there are similarities between the sensation of vibration and the sense of touch, 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 the sense of vibration, spiders are the most sensitive, unmatched by other animals. Although the spider's vision is poor, it has a very developed sense of vibration and sharpening the stove, as long as the insect falls on the web, a small pull, it can feel, and according to the signal, quickly and accurately find Kunyin to dress up as an insect, feast on it, and have 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 rushes towards the female spider as if she were any other insect, and then the male swims or retreats 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. Spiders rely on their vibrational senses to hunt and mate, and it's no wonder that their vibrational senses are particularly sensitive and unmatched by 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...
