Do Spiders Scream When You Burn Them?
WouterYou might have heard that spiders can make noises. They use vibrations to scare away predators, and make sounds to attract mates. Some of these sounds are loud enough for humans to hear.
One type of sound is called stridulation. The sound is produced when a spider rubs its body parts together. Other types of sound include hissing and purring. It is important to keep in mind that some spiders can’t hear human sounds.
Another type of sound is called song. This sound is produced by the vibrations of a spider’s abdomen and thorax rubbing against each other. Depending on the species, this type of sound can be more subtle than hissing.
Some spiders can also hear vibrations of airborne sounds. For example, a male jumping spider can hear the sound of a person dancing in the air. If he thinks that there is a threat, he may freeze or move away from the danger.
There are also wolf spiders that can make a purring sound. These spiders can be found in the deserts of America. However, they are not true spiders. In fact, they are wind scorpions.
A spider’s auditory sense ranges from 100 hertz to 10,000 hertz. It is thought that most spiders can only detect things that are close to them.
To test whether spiders can detect sounds, scientists tested one species of spider. This spider, the European garden spider, was built on a surface made of artificial substrates. Using the spider’s brain sensor, the researchers made different noises.
