The common misconception among people with snakes is that they are deaf. This assumption is mainly due to the fact that a snake has no ear on the outside. They do, however, have inner ears, which gives them the ability to hear well.

We know sound waves travel invisibly, and therefore we can't see them. The eardrum experiences vibration from these waves, hitting us at various frequency levels, and the result is we hear something.

This is not very different from how snakes hear. The main difference is that those sound wave frequencies are felt in the ground by the snake, whereas the sound waves we hear are from airwaves.

The Basic Design of Snakes Hearing?

Anytime something moves across the ground it creates vibrations. This also includes animals and people. Most animals don’t take notice of these vibrations, but a snake does.

When the wave reaches the snake, it is picked up by the bones and muscles in the snake's lower jaw. These vibrations are focused into an organ called the cochlea that gathers the sound for processing by the snake's inner ear.

The Advanced Design

It was believed that snakes could “hear” but couldn’t localize sounds for a long time. In other words, they couldn’t pinpoint where something was and had to rely on their poor eyesight and a keen sense of smell to home in on their prey.

Science has discovered that a snake's jaw's elasticity allows it to localize vibrations traveling through the ground, aiding the snake in determining which direction a sound is coming from.

You can find more details about how this works in this article that gives an overview of a study done by the University of Munich and University of Kansas researchers. The overview is that the snakes hinged jaw allows them to pick up the vibrations independently of one another depending on their side.

According to the study, there is evidence that the snake's auditory neurons create a topographical map that allows them to pin-point prey by the vibrations they create. In a nutshell, it is a form of echolocation.

Fascinating right? If you are a snake lover like us, we are sure it's exciting to you also. There are many similarities to humans, and science is continuously uncovering some incredible snake discoveries.

The more we know about snakes, the better we can care for them and give them what they need to thrive in an environment we provide for them.
