Firstly, it’s important to clarify that tarantulas, including the ones labeled as “screaming” tarantulas, don’t actually scream in the way humans do. They don’t have vocal cords or lungs to produce such sounds. The term “screaming tarantula” is a bit of a misnomer and can be misleading.

The Truth Behind the Name

The “screaming” part comes from a defense mechanism that some tarantula species use. When threatened, these tarantulas can produce a screaming sound by rubbing their legs against their body, a process known as stridulation. This sound can be startling and may seem like a scream to an unsuspecting listener. It’s their way of saying, “Back off!”

Species Known for Screaming

Caring for screaming Tarantulas

If you’re considering keeping a screaming tarantula as a pet, it’s important to understand their needs and behaviors. Here are a few tips:

  • Provide a suitable habitat: screaming tarantula needs a spacious enclosure with proper humidity and temperature.
  • Handle with care: The tarantula can be defensive, so it’s best to minimize handling and respect his space.
  • Offer a proper diet: Feed them a diet of appropriate-sized insects like crickets, roaches, and mealworms.

Why Do Tarantulas scream?

The screaming sound serves as a warning to predators and potential threats. It’s part of the tarantula’s defense strategy, along with other tactics like rearing up, showing their fangs, or even flicking urticating hairs. The goal is to scare off the threat without engaging in a fight. But why do tarantulas scream? Let’s explore the reasons behind this behavior in simple terms.

Defense Mechanism

The primary reason tarantulas scream is for defense. When they feel threatened or scared, they produce a screaming sound to ward off potential predators. This sound is made by rubbing their legs against their body or by forcing air through their mouthparts. The scream serves as a warning sign, indicating that the tarantula is ready to defend itself if necessary.


Tarantulas also use screaming as a form of communication, especially during mating season. Male tarantulas might scream to attract females or to assert dominance over other males. This form of communication helps them navigate social interactions and find a mate.

Stress Response

screaming can also be a sign that a tarantula is stressed or uncomfortable. Changes in their environment, such as loud noises, sudden movements, or improper habitat conditions, can trigger this stress response. It’s important for tarantula owners to observe their pet and ensure their living conditions are suitable and stress-free.


While the term “screaming tarantula” might conjure up eerie images, the reality is less dramatic. These fascinating creatures don’t scream in the human sense, but they do have a unique way of making their presence known when they feel threatened. The screaming sound of some tarantula species is just one of the many intriguing aspects of their behavior, making them a captivating subject for both arachnid enthusiasts and the curious-minded.

Their ability to produce sound as a defense mechanism is a testament to their adaptability and survival skills. Whether you’re an enthusiast or a potential tarantula keeper, understanding and respecting these remarkable spiders is key to appreciating their unique place in nature.
