Meeting Abstract 81.4  Friday, Jan. 7  Kissing and scraping: the intramandibular joint in Helostoma temmincki FERRY, LA*; GIBB, AC; KONOW, N; Arizona State University; Northern Arizona University; Brown University Lara.Ferry@asu.edu The kissing gourami, Helostoma temmincki, is a monotypic, enigmatic tropical freshwater fish, well known for displaying a ‘kissing behavior’— so named because the upper and lower jaws […]

Meeting Abstract 81.1  Friday, Jan. 7  Functional and morphological convergence in durophagous moray eels REECE, JOSHUA S*; MEHTA, RITA S; ALFARO, MICHAEL; Univ. of California, Santa Cruz; Univ. of California, Santa Cruz; Univ. of California, Los Angeles josh830@gmail.com Does functional convergence in diet result from morphological convergence? Morphology is constantly changing to maximize performance in response to […]

Meeting Abstract 81.3  Friday, Jan. 7  Finite element analysis of crushing teeth CROFTS, S.B.*; SUMMERS, A.P.; University of Washington, Friday Harbor Labs; University of Washington, Friday Harbor Labs croftss@uw.edu A number of lineages of fishes include durophagous members; fishes that have modified their pharyngeal or oral jaws to allow them to eat hard prey. Here we explore […]

Meeting Abstract 81.2  Friday, Jan. 7  Bite force production in Kyphosidae MORAN, C.J.*; FERRY, L.A.; Moss Landing Marine Labs cmoran.mlml@gmail.com The modeling of force production in fish jaws has been a large area of research in fish ecomorphology. Force production is especially important when diet items are firmly attached to substrate, such as in herbivory. In the […]

Meeting Abstract 80.6  Friday, Jan. 7  Prey Processing in Elasmobranchs STOEHR, A/A*; WILGA, C/D; ALLEN, R/M; Univ. of Massachusetts, Dartmouth; Univ. of Rhode Island; Ross University astoehr@umassd.edu Despite many recent studies focusing on capture in fishes, post-capture behavior remains relatively unexplored. It is unknown if the mechanics of prey processing, an integral component of the feeding process, […]

Meeting Abstract 80.2  Friday, Jan. 7  Mechanics, hydrodynamics and energetics of blue whale lunge feeding: predatory strategies and efficiency dependence on krill density GOLDBOGEN, Jeremy, A.*; CALAMBOKIDIS, John; MCKENNA, Megan; OLESON, Erin; POTVIN, Jean; PYENSON, Nick; SCHORR, Greg; SHADWICK, Robert; University of California, San Diego; Cascadia Research Collective; University of California, San Diego; NOAA; Saint Louis University; […]

Meeting Abstract 80.3  Friday, Jan. 7  Functional Morphology of the Feeding Apparatus in Hammerhead Sharks (Sphyrnidae): a Phylogenetic Perspective MARA, KR*; MOTTA, PJ; University of South Florida; University of South Florida kmara@mail.usf.edu Because sphyrnid sharks possess cranial morphologies with extreme variation, they can be used to address questions about the evolution of cranial design and investigate the […]

Meeting Abstract 80.5  Friday, Jan. 7  Feeding kinematics in batoids: comparing species with and without cephalic lobes MULVANY, SM*; MOTTA, PJ; Univ. of S Florida; Univ. of S Florida smulvany@mail.usf.edu Many benthic, undulatory batoids utilize their entire body to pin and manipulate prey during feeding. The general feeding behavior consists of forming a tent around the prey […]

Meeting Abstract 80.4  Friday, Jan. 7  Biomechanics of Prey Capture in Elasmobranchs WILGA, C/D*; STOEHR, A/A; DUQUETTE, D/C; ALLEN, R/M; University of Rhode Island; University of Massachusetts Dartmouth; University of New Hampshire; Ross University cwilga@uri.edu The feeding behavior of sharks and skates is compared to investigate suction and bite mechanisms. Suction flow is generated by rapid expansion […]

Meeting Abstract 80.1  Friday, Jan. 7  A computational modelling perspective on buccal expansion dynamics and water flow patterns in suction feeding fish VAN WASSENBERGH, S*; AERTS, P; Univ. Antwerpen; Univ. Antwerpen sam.vanwassenbergh@ua.ac.be By performing a sudden expansion of the mouth cavity while approaching a prey, suction feeders generate a flow of water that draws the prey into […]
