Not only can snakes hear sounds traveling through the air, researchers find, but different species react differently to what they hear.
The following essay is reprinted with permission from The Conversation, an online publication covering the latest research.
Our research, which included 19 different snakes from seven species, reveals that not only do snakes have airborne hearing, but that different species react differently to what they hear. For our experiments, we collaborated with the Queensland University of Technology’s School of Creative Practice to fit-out a soundproof room and test one snake at a time.
But our research is the first to investigate how multiple snake species respond to sounds in a space where they can move freely. We also used an accelerometer to detect whether the sounds produced ground vibrations. In this way we confirmed the snakes were indeed registering airborne sounds, and not just feeling ground vibrations.
In contrast, three other genera – Acanthophis , Oxyuranus and Pseudonaja – were more likely to move away from sound, signalling potential avoidance behaviour.
