Eigenmannia Jamming Avoidance Response (IMAGE) Optica Caption Researchers developed and demonstrated a light-based device that mimics the jamming avoidance response of Eigenmannia fish. These fish emit an electrical field for sensing and communication and use a jamming avoidance response system to move the frequency of their signal away from other signals that could potentially cause interference Credit Original photo by Will Kirk, Courtesy of Wikipedia, Creative Commons Attribution Creative Commons, Attribution 2.5 Generic license.
