In water, gravity is counter-balanced by buoyancy, hence fish are recoiled backwards after every bite they take from the substrate. To overcome this recoil and maintain contact with the algae covered substrate, fish need to generate thrust while feeding. However, the locomotory performance of reef herbivores in the context of feeding has hitherto been ignored. We used a three-dimensional high-speed video system to track mouth and body kinematics during<jats:italic>in situ<\/jats:italic>feeding strikes of fishes in the genus<jats:italic>Zebrasoma<\/jats:italic>, while synchronously recording the forces exerted on the substrate. These herbivores committed stereotypic and coordinated body and fin movements when feeding off the substrate and these movements determined algal biomass removed. Specifically, the speed of rapidly backing away from the substrate was associated with the magnitude of the pull force and the biomass of algae removed from the substrate per feeding bout. Our new framework for measuring biting performance<jats:italic>in situ<\/jats:italic>demonstrates that coordinated movements of the body and fins play a crucial role in herbivore foraging performance and may explain major axes of body and fin shape diversification across reef herbivore guilds.<\/jats:p>","DOI":"10.1098\/rspb.2020.1903","type":"journal-article","created":{"date-parts":[[2020,11,11]],"date-time":"2020-11-11T00:05:42Z","timestamp":1605053142000},"page":"20201903","update-policy":"https:\/\/doi.org\/10.1098\/crossmark-policy","source":"Crossref","is-referenced-by-count":26,"title":["Work that body: fin and body movements determine herbivore feeding performance within the natural reef environment"],"prefix":"10.1098","volume":"287","author":[{"ORCID":"https:\/\/orcid.org\/0000-0002-9630-3027","authenticated-orcid":true,"given":"Tal","family":"Perevolotsky","sequence":"first","affiliation":[{"name":"School of Zoology, Faculty of Life Sciences, Tel Aviv University, Tel Aviv 69978, Israel"},{"name":"The Inter-University Institute for Marine Sciences, POB 469, Eilat 88103, Israel"}],"role":[{"vocabulary":"crossref","role":"author"}]},{"ORCID":"https:\/\/orcid.org\/0000-0001-7989-9124","authenticated-orcid":true,"given":"Christopher H.","family":"Martin","sequence":"additional","affiliation":[{"name":"Department of Integrative Biology, Berkeley, CA, USA"},{"name":"Museum of Vertebrate Zoology, University of California, Berkeley, CA, USA"}],"role":[{"vocabulary":"crossref","role":"author"}]},{"given":"Asaph","family":"Rivlin","sequence":"additional","affiliation":[{"name":"The Inter-University Institute for Marine Sciences, POB 469, Eilat 88103, Israel"}],"role":[{"vocabulary":"crossref","role":"author"}]},{"ORCID":"https:\/\/orcid.org\/0000-0002-2334-2551","authenticated-orcid":true,"given":"Roi","family":"Holzman","sequence":"additional","affiliation":[{"name":"School of Zoology, Faculty of Life Sciences, Tel Aviv University, Tel Aviv 69978, Israel"},{"name":"The Inter-University Institute for Marine Sciences, POB 469, Eilat 88103, Israel"}],"role":[{"vocabulary":"crossref","role":"author"}]}],"member":"175","published-online":{"date-parts":[[2020,11,11]]},"reference":[{"key":"e_1_3_6_2_2","doi-asserted-by":"publisher","DOI":"10.1111\/j.1420-9101.2006.01227.x"},{"key":"e_1_3_6_3_2","doi-asserted-by":"publisher","DOI":"10.1093\/icb\/icm021"},{"key":"e_1_3_6_4_2","doi-asserted-by":"publisher","DOI":"10.1016\/0022-5193(74)90202-1"},{"key":"e_1_3_6_5_2","doi-asserted-by":"publisher","DOI":"10.1098\/rsbl.2007.0509"},{"key":"e_1_3_6_6_2","doi-asserted-by":"crossref","first-page":"3445","DOI":"10.1242\/jeb.205.22.3445","article-title":"Use of sonomicrometry demonstrates the link between prey capture kinematics and suction pressure in largemouth bass","volume":"205","author":"Sanford CPJ","year":"2002","journal-title":"J.
