Ocean Monitoring by Jellyfish
US Scientists Enable Jellyfish to Swim 3-times Faster Source: Caltech New Invention with Big Potential to Monitor Health of Oceans Scientists at Stanford University and Caltech have created a pacemaker-like device that enables natural jellyfish to swim three times their normal speed. The microelectronic, pulsing, tiny, prosthetic device generates electric jolts that make the fish triple their speed while using just twice as much energy. The scientists and engineers involved in the project says the device causes no additional stress to the sea creatures. They say the potential for this system is as vast as the ocean itself. Network of Live Ocean Monitors The scientific team says the combination of speed and energy efficiency from this device opens the possibility of using jellyfish to gather data from across the world's oceans. They envision equipping the jellyfish with sensors to track ocean temperatures, salinity and oxygen levels. They say this could
