LANDBERG, T.*; AZIZI, E.; Univ.of Massachusetts Amherst: Aquatic escape performance through ontogeny and metamorphosis of spotted salamanders, Ambystoma maculatum Spotted salamanders begin development inside a gelatinous egg mass and then hatch as larvae into ephemeral aquatic habitats where they grow and metamorphose into terrestrial adults that eventually return to water to breed. Throughout this complex […]

PIRTLE, Thomas J; SATTERLIE, Richard A; Abilene Christian University; Arizona State University: The role of cyclic GMP and cyclic AMP on mediating the modulation of Clione limacina swim behavior The marine pteropod mollusk, Clione limacina, exhibits behaviorally relevant locomotor speed changes in response to various stimuli. Clione accelerate swimming during prey capture and as an […]

LONG, JR., J H; ETNIER, S; PABST, D A; JOHNSON, M; MCLELLAN, W A; Vassar College; Butler University; University of North Carolina, Wilmington; Vassar College; University of North Carolina, Wilmington: Swimming Cetaceans: Hydrodynamics, Body Stiffness, and the Scaling of Performance Our goal is to integrate external and internal forces in a model that offers a […]

MADDEN, P.G. *; LAUDER, G.V.; Harvard University; Harvard University: Pectoral fin locomotion in fishes: fin ray deformation and material properties Fish pectoral aspect ratio and planform have been studied but little attention has been paid to fin ray flexibility and planform changes during a fin beat. Such changes in fin shape may dramatically affect the […]

SATTERLIE, RA; PIRTLE, TJ; Arizona State University; Abilene Christian University: Organization of Parapodial Dorsoventral Muscles in the Pteropod Mollusc, Clione limacina A great deal is known about swim control in Clione, including the neural basis of central pattern generation, modulation of swim activity during accelerations, and the architecture of swim muscle in the wing-like parapodia. […]

THOMPSON, J.T.; KIER, W.M.; St. Joseph’s University; Univ. of North Carolina: Ontogeny of circular muscle ultrastructure and implications for jet locomotion in oval squid (Sepioteuthis lessoniana) We investigated growth-related changes in the morphology and movement of the mantle of the Oval Squid, Sepioteuthis lessoniana. The maximum rate of mantle contraction during escape-jet locomotion was highest […]

KERFOOT, J.R.*; SCHAEFER, J.F.; Florida Institute of Technology; Southern Illinois University Edwardsville: Microhabitats and Ecomorphologies of Cottus species Phenotypes of fishes act as fundamental constraints upon their ecologies; morphology shapes ecological attributes through its effect on performance. Field and laboratory studies were conducted to investigate the relationships between morphological attributes and microhabitat use in Cottus […]

TYTELL, Eric D.; Harvard University: Linking wake structure, kinematics, and mechanics for oscillatory propulsion Many studies have examined either the kinematics or the hydrodynamics of fish swimming, but few have looked at both simultaneously. By directly observing the wakes that result from different kinematics, a more detailed description of the underlying mechanism may be produced. […]

HORNSTRA, H. M.*; HERREL, A.; MONTGOMERY, W. L.; Northern Arizona University, Flagstaff; University of Antwerp, Belgium; Northern Arizona University, Flagstaff: Gas bladder movement in lionfishes: a novel mechanism for control of pitch Lionfish (Pterois volitans) are crepuscular reef predators that stalk their prey and often hover just above the reef, maintaining unique body positions with […]

THORSEN, D/H*; CASSIDY, J/J; HALE, M/E; The University of Chicago; The University of Chicago; The University of Chicago: Development of pectoral fin morphology and locomotion in the zebrafish Danio rerio Pectoral fins serve a variety of locomotor functions for fishes including propulsion, stabilization and maneuvering. The function of pectoral fins can change through development and […]
