Involved in many daily activities, grasping has been extensively studied in primates and other mammals. Yet, other groups of tetrapods, including anurans, have also evolved significant forelimb prehensile capacities that are often thought to have originated in an arboreal context. However, grasping is also observed in aquatic species. Yet, how aquatic frogs use their forelimbs to capture and manipulate prey remains largely unknown. The aim of this study is to explore how the grasping and manipulation of food items in aquatic frogs is impacted by food properties such as size and mobility. To do so we use the aquatic frog Xenopus laevis and quantified the use of the hands and fingers while processing mobile and stationary prey of different sizes (small, intermediate, and large prey). Our results show that X. laevis is able to individualize the digits and that the mobility and the length of the prey significantly influence the kind of grasping pattern used. Grasping abilities are thus not specific to terrestrial, nor arboreal species. These results illustrate how prey properties impact grasping and manipulation strategies in an aquatic frog and shed further light on the ecological contexts that may have given rise to the origin of grasping in frogs.<\/jats:p>","DOI":"10.1242\/jeb.159442","type":"journal-article","created":{"date-parts":[[2017,10,6]],"date-time":"2017-10-06T00:40:25Z","timestamp":1507250425000},"source":"Crossref","is-referenced-by-count":12,"title":["The effect of food properties on grasping and manipulation in the aquatic frog,<i>Xenopus laevis<\/i>"],"prefix":"10.1242","author":[{"given":"Aude","family":"Anzeraey","sequence":"first","affiliation":[{"name":"UMR 7179 C.N.R.S\/M.N.H.N., D\u00e9partement Adaptations du Vivant, 75005, Paris Cedex 5, France"}],"role":[{"vocabulary":"crossref","role":"author"}]},{"given":"Madeleine","family":"Aumont","sequence":"additional","affiliation":[{"name":"UMR 7179 C.N.R.S\/M.N.H.N., D\u00e9partement Adaptations du Vivant, 75005, Paris Cedex 5, France"}],"role":[{"vocabulary":"crossref","role":"author"}]},{"given":"Thierry","family":"Decamps","sequence":"additional","affiliation":[{"name":"UMR 7179 C.N.R.S\/M.N.H.N., D\u00e9partement Adaptations du Vivant, 75005, Paris Cedex 5, France"}],"role":[{"vocabulary":"crossref","role":"author"}]},{"given":"Anthony","family":"Herrel","sequence":"additional","affiliation":[{"name":"UMR 7179 C.N.R.S\/M.N.H.N., D\u00e9partement Adaptations du Vivant, 75005, Paris Cedex 5, France"}],"role":[{"vocabulary":"crossref","role":"author"}]},{"ORCID":"https:\/\/orcid.org\/0000-0002-0542-975X","authenticated-orcid":false,"given":"Emmanuelle","family":"Pouydebat","sequence":"additional","affiliation":[{"name":"UMR 7179 C.N.R.S\/M.N.H.N., D\u00e9partement Adaptations du Vivant, 75005, Paris Cedex 5, France"}],"role":[{"vocabulary":"crossref","role":"author"}]}],"member":"237","published-online":{"date-parts":[[2017,1,1]]},"reference":[{"key":"2021042523131698000_JEB159442C1","doi-asserted-by":"publisher","first-page":"536","DOI":"10.1111\/j.1469-7580.2010.01278.x","article-title":"Comparative anatomy, homologies and evolution of the pectoral and forelimb musculature of tetrapods with special attention to extant limbed amphibians and reptiles","volume":"217","author":"Abdala","year":"2010","journal-title":"J.
