Meeting Abstract 112-5  Thursday, Jan. 7 09:00  What can tails tell fish? How caudal touch mediates startle behavior KATZ, HR*; LIU, YC; HALE, ME; Univ. of Chicago; Vollum Institute, Oregon Health and Science Univ.; Univ. of Chicago katz20h@uchicago.edu The S-start startle behavior is produced in response to caudal stimuli in zebrafish and other taxa. By examining the […]

Meeting Abstract 112-3  Thursday, Jan. 7 08:30  Pectoral fins of the catfish Pimelodus pictus can function as passive touch sensors HARDY, A.R.*; STEINWORTH, B.M.; HALE, M.E.; Univ. of Chicago; Whitney Laboratory for Marine Biosciences; Univ. of Chicago arhardy7@uchicago.edu Mechanosensation is fundamental to many tetrapod limb functions yet remains largely uninvestigated in the paired fins of fishes, limb […]

Meeting Abstract 112-6  Thursday, Jan. 7 09:15  Muscle activity during forward accelerations versus steady swimming in bluegill sunfish SCHWALBE, MAB*; WISE, TN; BODEN, AL; TYTELL, ED; Tufts University margot.schwalbe@tufts.edu Fishes need to swim long distances efficiently and accelerate quickly to escape predators or capture prey. To swim, fish contract the muscles on either side of their bodies […]

Meeting Abstract 112-4  Thursday, Jan. 7 08:45  Losing one’s sense of control: how proprioceptive feedback impacts labriform swimming AIELLO, BR*; OLSEN, AM; WESTNEAT, MW; HALE, ME; Univ. of Chicago braiello@uchicago.edu http://home.uchicago.edu/~braiello Proprioceptive feedback, the sense of movement and position of one’s body elements in space, is critical to the motor performance of many animals. The pectoral fins […]

Meeting Abstract 112-1  Thursday, Jan. 7 08:00  How fish schooling improves swimming performance? DAGHOOGHI, M; BORAZJANI, I*; University at Buffalo, State University of New York; University at Buffalo, State University of New York iman@buffalo.edu Fish schooling is typically observed in many fish species, which is thought to provide hydrodynamic advantages. Previous theoretical models have predicted improvements in […]

Meeting Abstract 112-2  Thursday, Jan. 7 08:15  Batoid locomotion: integrative study of mechanics and energetics in the little skate DI SANTO, V*; KENALEY, CP; LAUDER, GV; Harvard University; Harvard University; Harvard University vdisanto@fas.harvard.edu Batoid fishes are unique among elasmobranchs in having dorso-ventrally flattened bodies with largely expanded pectoral fins that form a disc. Benthic batoids lift from […]
