And so it's not surprising, perhaps, that in July of this year, Shark Attack Mitigation Systems in collaboration with the University of Western Australia Oceans Institute made an announcement which captured the attention of the worldwide media and of ocean users worldwide, and that was around the development of technology to mitigate or reduce the risk of shark attack based on the science of what sharks can see.
We know that sharks use a range of sensors when they engage, particularly for attack, but the sight sensor is the one that they use to identify the target, and particularly in the last number of meters before the attack.
