![]() In our experiments, both of these snakes appeared to have acute senses. This means they may be vulnerable to daytime predators such as raptors. Zdenekīrown snakes and taipans are active foragers that rapidly pursue their prey during the day. ![]() In this way we confirmed the snakes were indeed registering airborne sounds, and not just feeling ground vibrations.Ī common death adder ( Acanthophis antarcticus) in an ambush position at Mount Glorious, Queensland. Christina N. We also used an accelerometer to detect whether the sounds produced ground vibrations. In another, researchers surgically implanted electrodes into the brains of partially anaesthetised snakes, detecting electrical potentials in response to sound up to 600Hz.īut our research is the first to investigate how multiple snake species respond to sounds in a space where they can move freely. In one previous study, researchers hung western diamondback rattlesnakes ( Crotalus atrox) in a steel mesh basket and observed their restricted behaviours in response to sound frequencies between 200Hz and 400Hz. ![]() For comparison, the human voice range is about 100–250Hz, and birds chirp at about 8,000Hz. Using silence as our control, we played one of three sounds, each including a range of frequencies: 1–150Hz, 150–300Hz and 300–450Hz. The coastal taipan was one of 19 snake species used in our research. Christina Zdenek, Author providedįor 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. ![]()
