Death adders are predators that use their tails as a lure to catch prey. They are not fast movers, so avoiding large vertebrates such as kangaroos, wombats, or humans is crucial to their survival. To do this, they tend to avoid making noise. Brown snakes and taipans, on the other hand, are active foragers that hunt during the day and may be susceptible to attacks from predators such as raptors. However, these snakes have acute senses and can respond to sound, which debunks the myth that snakes are deaf. While snakes can hear, they can only perceive low frequencies under 600Hz, unlike humans who can hear a wider range. In experiments, snakes responded to sounds played at a range of frequencies, including those of the human voice. Therefore, it is safe to say that snakes can hear loud human voices and screams, but it is unclear if they can hear normal conversations. Christina N.

FAQ
1. Can snakes really hear us scream?
Yes, according to a new study conducted by scientists from the University of Texas at Austin, snakes can hear sounds in the same frequency range as human screams. This is surprising, as snakes lack external ears and were previously thought to be deaf to airborne sounds.
2. How do snakes hear without ears?
Snakes have a unique way of detecting sound through their lower jaws. They have a specialized bone called the quadrate bone that can pick up vibrations from the ground or the air and transfer them to the inner ear. This allows them to detect prey, predators, and other sounds in their environment.
3. Why is it important to study snake hearing?
Understanding how snakes perceive sound can help researchers develop better methods for controlling and managing snake populations. It can also provide insights into the evolution of snake sensory systems and how they have adapted to their environments.
4. Can snakes hear music or other complex sounds?
While snakes can hear sounds in the same frequency range as human screams, they may not be able to process more complex sounds like music or speech due to their simple brain structure. Further research is needed to determine the extent of their auditory capabilities.
5. Do all snakes have the same hearing abilities?
No, different species of snakes may have different hearing abilities depending on their environment and lifestyle. Some snakes may rely more heavily on their sense of smell or vision, while others may use their hearing to locate prey or avoid predators.
6. Can loud noises harm snakes?
Yes, loud noises can cause stress and discomfort in snakes, which can have negative impacts on their health and behavior. In addition, exposure to loud noises from human activities like construction or traffic can disrupt their natural habitat and lead to habitat loss.
7. Are there any implications for human safety?
While snakes can hear human screams, there is no evidence to suggest that they are attracted to or provoked by them. In fact, most snakes will try to avoid humans if possible. However, it is still important to be cautious around snakes and avoid provoking or handling them.
8. What other surprising abilities do snakes have?
Snakes are known for their unique adaptations, including their ability to swallow prey whole and their use of infrared vision to detect heat. Some species of snakes can also glide through the air using their bodies as wings, while others can sense vibrations in the ground to detect prey.
