The spider suddenly felt the sound of the fly struggling. The spider quickly crawls toward its web, ready for a meal. However, I found nothing online. Do spiders have hearing?

Spiders don't have ears in the usual sense, so how do they "hear"? The answer is net + leg hair. The web woven by a spider is somewhat similar to the human eardrum, which can amplify and transmit vibrations in the air. Every tiny vibration in the air was transmitted to the spider's legs through the spider web. The hairs on spider legs are very sensitive sensory organs that can pick up very small vibrations.

Test with a violin. When the frequency of the sound emitted by the violin is the same as the frequency of the fly hitting the web and struggling, the spider's leg endings are sensitive. The hair reacted. This makes the spiders mistakenly believe that prey is coming. Therefore, the spiders have no hearing. They capture the sound waves through the sensitive leg hairs and determine whether there is prey trapped in the web.

Spiders’ hearing is better than ours

Through this method, spiders can “hear” what is happening around them. Not only can they accurately determine their location, but they can also approximate the location through the frequency of vibrations. Determine whether the other party is a threat, and even determine what the other party is. It is even more powerful than our human ears. The sound frequencies that we humans can hear are very narrow, but spiders can "hear" "sounds" in a wide range of frequencies.
