Can Snakes Hear?

Contrary to popular belief, snakes are not deaf and can hear well. However, unlike other reptiles, snakes do not have an eardrum or tympanic cavity. They have also lost other hearing structures throughout their evolution.

How do snakes hear?

Snakes hear through vibrations they perceive thanks to their jaw bones. Therefore, although they do not have a visible ear similar to ours, they can hear through vibrations. This way, they are able to determine the location thanks to the sound waves produced by movement. This occurs due to sound waves that are produced on these surfaces, which radiate around them very quickly, allowing snakes to hunt their prey without failing.

Snakes actually have a well-formed inner ear, with no eardrum, that is directly connected to their jaw bone (quadrate bone). This bone rests on the ground and slightly moves in response to vibrations while they slither on the ground. Snakes have a hearing range of 80-600 Hz, although some species can hear up to 1000 Hz. Given that the average human voice is around 250 Hz, snakes can actually hear us talk. Nevertheless, snakes can better perceive low-frequency sounds. Interestingly, this adaptation aids them in detecting the movements of predators and prey, providing a significant survival advantage in their natural habitats.

Now that we know that snakes can hear through the vibrations of sound waves, it's time to get to know their hearing system as it's very different to ours. First things first, snakes have lost various hearing structures and currently do not have an external ear or even an eardrum. Nevertheless, they do have an inner ear that consists of:

• Hair cells
• Auditory nerve fibers
• Basilar membrane
• Cochlear duct
• Semicircular canals
• Sacculus

This inner ear structure is directly connected to their jawbone, in other words, the mandible. This consists of:

• Compound jawbone
• Columella auris
• Quadrate
• Supratemporal

These two structures work together to perceive movement through sound waves. As we've previously mentioned, snakes can impressively perceive low-frequency sounds. This unique system allows them to be incredibly sensitive to the environment, even detecting subtle changes that might indicate the presence of danger or food. Such a system is a remarkable example of evolutionary adaptation, highlighting how snakes have thrived in diverse ecosystems worldwide.
