Tarantulas make sounds! Many pet owners don’t know this.
These big, fuzzy spiders from the Theraphosidae family can make noises that tell us what they’re feeling.
Learning about tarantula sounds helps you be a better pet owner. In this guide, you’ll learn what different tarantula noises mean, how they make them, and which kinds of tarantulas are the loudest.
Types of Tarantula Sounds and Their Meanings
Stridulation: The Main Way Tarantulas Make Noise
Stridulation sounds happen when tarantulas rub body parts together.
Think of it like rubbing a stick on a fence – it makes noise! Tarantulas use these body parts to make sounds:
- Their legs against their body
- Their pedipalps (small leg-like parts near the mouth) against chelicerae (fangs)
- Their legs against other legs
Scientists found that sounds made by tarantulas are between 1-15 kHz. Most sounds are about as loud as normal talking (40-65 dB).
“Tarantula stridulation mechanisms are one of the most interesting ways spiders communicate. They’ve been using these techniques for about 250 million years!” – Dr. Linda Rayor, spider behavior researcher
Hissing Sounds: When Tarantulas Feel Threatened
Some tarantulas make hissing behavior sounds when they feel unsafe. The Goliath Birdeater is known for loud hisses.
If your pet tarantula hisses, it means:
- It feels scared
- It wants you to back away
- It might be getting ready to defend itself
Mexican Red-Knee Tarantulas don’t hiss as much as other kinds. Each species has its own sound patterns.
Clicking and Tapping Noises
Some tarantulas make clicking noises by tapping their legs. This is different from stridulation sounds. Tapping happens when:
- Males look for mates
- Tarantulas mark territory
- They send warning signals to other animals
How to Understand Your Tarantula’s Sound Messages
Defense Sounds vs. Territory Sounds
You can tell the difference between defensive stridulation and territorial sounds by watching your tarantula’s body language:
Sound Purpose | Body Position | Sound Type | How Often It Happens |
---|---|---|---|
Defense | Raised front legs, fangs out | Loud, sharp hissing | 85% of threat displays |
Territory | Tapping front legs | Soft clicking | Most common at night |
Stress | Fast movements, hair flicking | Short bursts of sound | Happens with temperature changes |
When tarantulas make defense noises, they might also kick tiny hairs called urticating hairs. These can irritate skin and eyes.
Stress and Worry Signals
Tarantulas make more sounds when they’re stressed. Signs of tarantula stress signals include:
- More sounds than normal
- Fast movements
- Refusing to eat
- Hair flicking
If your tarantula makes 64% more sounds when the room gets warmer (from 70°F to 85°F), it might be too hot!
Mating and Social Sounds
Male tarantulas make sounds 3.2 times more often during mating season.
These mating calls are part of their mating ritual. Males use acoustic communication to:
- Get females’ attention
- Show they aren’t a threat
- Prove they’re good mates
Common Tarantula Species and Their Unique Sounds
Old World Tarantulas (Africa, Asia)
Old World tarantulas make higher sounds (about 12 kHz) than other tarantulas. These spiders from Africa and Asia don’t have urticating hairs, so they rely more on sounds and threat posture sounds for defense.
The British Tarantula Society reports that these spiders are more likely to make threat assessment sounds than to run away.
New World Tarantulas (Americas)
New World tarantulas from North and South America make lower sounds (about 8 kHz). The Pamphobeteus antinous is one of the loudest species, according to the American Tarantula Society.
“The tarantula sound production differences between New and Old World species show how these animals evolved in different places. It’s fascinating to study these spider acoustic signals!” – Quote from the Journal of Arachnology
Arboreal vs. Ground-Dwelling Differences
Arboreal tarantulas (tree-dwelling) and terrestrial tarantulas (ground-dwelling) make different sounds:
- Arboreal tarantulas:
- Higher-pitched sounds
- More leg tapping
- Better at vibration detection
- Terrestrial tarantulas:
- Louder stridulation
- More body rubbing sounds
- Use setae vibration more
How to Record and Identify Your Tarantula’s Sounds
Recording Equipment and Tips
You can record your pet’s tarantula sound characteristics with:
- A smartphone with a sound app
- A small microphone placed near (but not in) the tank
- A vibration sensor under the tank
Remember that only 62% of tarantula sounds can be heard by human ears. Some sounds are too high or low for us to hear!
For more tips on recording your tarantula, check out the Arachnoboards forum, where spider experts share tarantula sound recording techniques.
Creating a Sound Profile for Your Pet
The Tarantula Keepers Guide suggests keeping track of your pet’s normal sounds. This helps you notice when something changes. Make notes about:
- When your tarantula makes sounds
- How loud they are
- What your tarantula is doing when making sounds
- If the sounds change with the seasons
Scientific Research on Tarantula Acoustics
Current Understanding and New Discoveries
Scientists are learning new things about tarantula communication methods all the time. Recent studies from the World Spider Conservation Network used tarantula noise interpretation to identify 16 endangered species!
Research from the University of Zurich shows that tarantula sound evolutionary purpose goes back 250 million years. This means spiders were making sounds before dinosaurs existed!
Why Tarantulas Evolved to Make Sounds
Tarantulas developed acoustic communication in spiders for many reasons:
- To scare away threats
- To find mates in the dark
- To mark territory
- To communicate with other tarantulas
The sounds tarantulas make with their stridulating organs have a 78% connection with how likely they are to attack. This means the louder the sound, the more serious the warning!
Final Thoughts
Understanding tarantula noises helps you be a better pet owner. By listening to your spider’s tarantula body part sounds, you can tell if it’s happy, scared, or stressed. Interpreting tarantula sounds takes practice, but it’s worth it!
Next time your tarantula makes noise, don’t worry! Now you know it’s just using tarantula sensory communication to tell you something.

Common Questions
- Are tarantula sounds dangerous? No, the sounds themselves can’t hurt you.
- Why is my tarantula making more noise than usual? It might be stressed, too hot, or feeling threatened.
- Can tarantulas hear sounds like we do? No, they feel vibrations using special hairs called trichobothria.
- Do baby tarantulas make sounds? Yes, but they’re much quieter.
- Which tarantulas are loudest? The Pamphobeteus antinous, Theraphosa blondi, and Psalmopoeus cambridgei.
- How can I tell if sounds mean my tarantula is angry? Look for raised front legs and exposed fangs.
- Do tarantulas talk to each other with sounds? Yes, especially during mating and territory disputes.
- Can tarantulas feel vibrations from other animals? Yes, they can detect movements as small as 0.05 mm!
While most people don’t realize it, tarantulas use subtle noises to communicate. Clicking, stridulation, and tapping are all ways they express distress, territoriality, or mating readiness. For more information on decoding tarantula sounds, visit Tarantula Care.
