To understand how jellyfish can outcompete effective visual hunters, such as fish, we investigate the energetics of propulsion. We find that jellyfish exhibit a unique mechanism of passive energy recapture, which can reduce metabolic energy demand by swimming muscles. Contrary to prevailing views, this contributes to jellyfish being one of the most energetically efficient propulsors on the planet. These results demonstrate a physical basis for the ecological success of medusan swimmers despite their simple body plan and have implications for bioinspired design, where low-energy propulsion is required.<\/jats:p>","DOI":"10.1073\/pnas.1306983110","type":"journal-article","created":{"date-parts":[[2013,10,7]],"date-time":"2013-10-07T23:17:51Z","timestamp":1381187871000},"page":"17904-17909","update-policy":"https:\/\/doi.org\/10.1073\/pnas.cm10313","source":"Crossref","is-referenced-by-count":192,"title":["Passive energy recapture in jellyfish contributes to propulsive advantage over other metazoans"],"prefix":"10.1073","volume":"110","author":[{"given":"Brad J.","family":"Gemmell","sequence":"first","affiliation":[{"name":"Whitman Center, Marine Biological Laboratory, Woods Hole, MA 02543;"},{"name":"Biology Department, Providence College, Providence, RI 02908;"}],"role":[{"vocabulary":"crossref","role":"author"}]},{"given":"John H.","family":"Costello","sequence":"additional","affiliation":[{"name":"Whitman Center, Marine Biological Laboratory, Woods Hole, MA 02543;"},{"name":"Biology Department, Providence College, Providence, RI 02908;"}],"role":[{"vocabulary":"crossref","role":"author"}]},{"given":"Sean P.","family":"Colin","sequence":"additional","affiliation":[{"name":"Whitman Center, Marine Biological Laboratory, Woods Hole, MA 02543;"},{"name":"Marine Biology\/Environmental Sciences, Roger Williams University, Bristol, RI 02809;"}],"role":[{"vocabulary":"crossref","role":"author"}]},{"given":"Colin J.","family":"Stewart","sequence":"additional","affiliation":[{"name":"Department of Mechanical Engineering, Virginia Polytechnic Institute and University, Blacksburg, VA 24061;
