Do Scorpions Make Sounds? Communication, Stridulation, and Owner Questions

Introduction

Many pet parents are surprised to learn that scorpions are usually quiet animals, but some species can make faint sounds. The best-known sound is stridulation, a rasping or hissing noise made when body parts rub together. Not every scorpion does this, and even in species that can, it is usually heard during defense, disturbance, or intense handling rather than during normal day-to-day activity.

Scorpions rely much more on vibration and touch than on airborne sound. They are extremely sensitive to vibrations in the ground, and they also use specialized sensory structures called pectines to gather information from the surface beneath them. In practical terms, that means your scorpion is more likely to react to footsteps, enclosure movement, or prey vibrations than to voices across the room.

For pet parents, a sudden hiss-like sound can be startling. In many cases, it means your scorpion feels threatened, stressed, or overhandled. It does not automatically mean illness. Still, if the behavior appears alongside weakness, trouble moving, repeated falls, or a recent sting incident involving another pet, it is smart to contact your vet for species-appropriate guidance.

Do scorpions actually make noise?

Yes, some scorpions can make audible noise, but many do not do it often enough for pet parents to notice. When sound happens, it is usually described as a soft hiss, scrape, or rasp. This is different from vocalization in mammals or birds. Scorpions do not have a voice box. Instead, sound is mechanical.

The main mechanism is stridulation, which means producing sound by rubbing one body part against another. Britannica describes stridulation broadly as a communication method in animals, and scorpions are among the arthropods known to use it. In the home, this sound is most likely to be noticed when a scorpion is startled during enclosure maintenance, prey introduction, or direct handling.

How do scorpions communicate if they are mostly silent?

Scorpions depend heavily on substrate vibrations, touch, and chemical cues. Research on scorpion orientation behavior shows they are highly tuned to vibrations traveling through sand or ground surfaces. Separate work on scorpion pectines also supports their role in sensing environmental and chemical information.

That matters for husbandry. A scorpion may respond strongly to tapping on the enclosure stand, sliding décor, or prey movement while seeming to ignore nearby conversation. If your pet scorpion freezes, raises its body, or becomes defensive during routine care, vibration sensitivity may be the reason.

What are pectines, and why do they matter?

Pectines are comb-like sensory organs on the underside of the scorpion. They sweep the ground as the animal walks and help detect chemical traces, texture, and mechanical cues. Studies of pectinal function and sensory processing suggest these organs are central to how scorpions explore their environment.

For pet parents, pectines help explain why a scorpion may seem very aware of tiny changes in substrate, humidity pockets, or prey movement. They also explain why rough handling or frequent enclosure vibration can be stressful even when the room itself seems quiet.

If my scorpion hisses, should I worry?

A hiss or rasp usually means defensive arousal, not friendliness or a request for attention. Common triggers include handling, sudden enclosure disturbance, prey that is too large, or environmental stress. Review the setup first: secure hides, correct substrate depth for the species, stable temperature gradients, and minimal unnecessary disturbance.

Call your vet if the sound is paired with abnormal posture, repeated flipping, inability to right itself, obvious injury, or if another household pet may have been stung. Merck notes that scorpion stings in companion animals are often painful and occasionally can cause more serious systemic signs, especially with bark scorpions in the US Southwest. If a dog or cat was stung, see your vet immediately.

Questions to Ask Your Vet

Bring these questions to your vet appointment to get the most out of your visit.

  1. You can ask your vet whether my scorpion’s sound is likely normal defensive stridulation or a sign of stress from husbandry.
  2. You can ask your vet which enclosure factors most often trigger defensive behavior in this species, including vibration, humidity, hides, and substrate depth.
  3. You can ask your vet how often this species should be handled, if at all, to reduce stress and injury risk.
  4. You can ask your vet whether my scorpion’s posture, movement, or feeding behavior suggests a medical problem rather than normal behavior.
  5. You can ask your vet what warning signs mean I need urgent care, such as weakness, repeated falls, or inability to right itself.
  6. You can ask your vet how to make enclosure cleaning less stressful for a vibration-sensitive arachnid.
  7. You can ask your vet what to do if my dog or cat is stung by this scorpion species at home.
  8. You can ask your vet whether there are local legal or safety considerations for keeping this species in my state or municipality.
