Zothecula (1870348) writes "Octopi and squid swim not by swishing a tail, but by expelling a jet of water. This allows them to move very quickly and quietly. Scientists from Germany’s Fraunhofer Institute for Manufacturing Engineering and Automation have now copied this system, in a propulsion system that could ultimately find use in boats, recreational watercraft, or submarines."
