Balaenopterids are characterized by their extreme lunge-feeding behaviour, a dynamic process that involves the engulfment of a large volume of prey-laden water at a high energetic cost. To investigate the consequences of scale and morphology on lunge-feeding performance, we determined allometric equations for fin whale body dimensions and engulfment capacity. Our analysis demonstrates that larger fin whales have larger skulls and larger buccal cavities relative to body size. Together, these data suggest that engulfment volume is also allometric, increasing with body length as<jats:inline-formula><jats:inline-graphic xmlns:xlink=\"http:\/\/www.w3.org\/1999\/xlink\" xlink:href=\"rspb20091680ileq1.gif\"\/><\/jats:inline-formula>. The positive allometry of the skull is accompanied by negative allometry in the tail region. The relative shortening of the tail may represent a trade-off for investing all growth-related resources in the anterior region of the body. Although enhanced engulfment volume will increase foraging efficiency, the work (energy) required to accelerate the engulfed water mass during engulfment will be relatively higher in larger rorquals. If the mass-specific energetic cost of a lunge increases with body size, it will have major consequences for rorqual foraging ecology and evolution.<\/jats:p>","DOI":"10.1098\/rspb.2009.1680","type":"journal-article","created":{"date-parts":[[2009,11,26]],"date-time":"2009-11-26T04:42:06Z","timestamp":1259210526000},"page":"861-868","update-policy":"https:\/\/doi.org\/10.1098\/crossmark-policy","source":"Crossref","is-referenced-by-count":72,"title":["Skull and buccal cavity allometry increase mass-specific engulfment capacity in fin whales"],"prefix":"10.1098","volume":"277","author":[{"given":"Jeremy A.","family":"Goldbogen","sequence":"first","affiliation":[{"name":"Department of Zoology, University of British Columbia, 6270 University Boulevard, Vancouver, British Columbia, Canada V6T 1Z4"}],"role":[{"vocabulary":"crossref","role":"author"}]},{"given":"Jean","family":"Potvin","sequence":"additional","affiliation":[{"name":"Department of Physics, Saint Louis University, 3450 Lindell Boulevard, St Louis, MO 63103, USA"}],"role":[{"vocabulary":"crossref","role":"author"}]},{"given":"Robert E.","family":"Shadwick","sequence":"additional","affiliation":[{"name":"Department of Zoology, University of British Columbia, 6270 University Boulevard, Vancouver, British Columbia, Canada V6T 1Z4"}],"role":[{"vocabulary":"crossref","role":"author"}]}],"member":"175","published-online":{"date-parts":[[2009,11,25]]},"reference":[{"key":"e_1_3_2_2_1","doi-asserted-by":"crossref","first-page":"1747","DOI":"10.1242\/jeb.205.12.1747","article-title":"High feeding costs limit dive time in the largest whales","volume":"205","author":"Acevedo-Gutierrez A.","year":"2002","journal-title":"J.
