Meeting Abstract 40-1  Sunday, Jan. 5 08:00 – 08:15  Substrate-based locomotion in young octopuses. HALE, ME*; GOOLSBEE, AW; University of Chicago, Chicago IL mhale@uchicago.edu Young Octopus bimaculoides (less than 60 days post-hatching) have well developed arms and arm-based locomotor movements. Using high-speed imaging and kinematic analyses we describe substrate associated locomotor movements in 20 young octopuses striding […]

Meeting Abstract 40-2  Sunday, Jan. 5 08:15 – 08:30  Sea Star Inspired Crawling and Bouncing HEYDARI, S*; PO, T; MCHENRY, MJ; KANSO, E; University of Southern California; University of California, Irvine; University of California, Irvine; University of Southern California sinaheyd@usc.edu http://scf.usc.edu/~sinaheyd/ The oral surface of sea stars is lined with arrays tube feet that enable them to […]

Meeting Abstract 40-6  Sunday, Jan. 5 09:15 – 09:30  Frogfish Pectoral Fin Functional Morphology AMPLO, HE*; FLAMMANG, BE; Rutgers Univeristy-Newark; New Jersey Institute of Technology hea7@njit.edu Frogfish (Family Antennariidae) are highly derived benthic, teleost fishes capable of performing three modes of locomotion: jetting, swimming, and substrate-based locomotion. Previous literature has described how frogfish use their limb-like pectoral […]

Meeting Abstract 40-4  Sunday, Jan. 5 08:45 – 09:00  Comparative biomechanics of submerged and emerged walking in the epaulette shark (Hemiscyllium ocellatum) TRAVIS, KG*; KAWANO, SM; California State Uni., Long Beach; George Washington Uni. kevin.travis@student.csulb.edu Epaulette sharks (Hemiscyllium ocellatum) are benthic fishes that commonly use a tetrapod-like “walking-trot” gait to move along the substrate and will occasionally […]

Meeting Abstract 40-5  Sunday, Jan. 5 09:00 – 09:15  Comparative Kinematics of Terrestrial Walking in Two Balitorid Loaches CRAWFORD, CH*; CERRATO-MORALES, CL; FLAMMANG, BE; New Jersey Institute of Technology; New Jersey Institute of Technology; New Jersey Institute of Technology crawford.callie@gmail.com Hillstream loaches (Balitoridae) inhabit the fast flowing hillstreams of South and Southeast Asia. These fishes have evolved […]

Meeting Abstract 40-3  Sunday, Jan. 5 08:30 – 08:45  Animated “Foot” Control During Walking in Skates GASSLER, TR*; FLAMMANG, BE; New Jersey Institute of Technology; New Jersey Institute of Technology trg22@njit.edu Skates are cartilaginous, dorsoventrally-flattened benthic fishes comprising more than 240 species. Several species have been observed to use the anterior lobe of their pelvic fins to […]

Tarsitano, M. *; Dickinson, M.: Visual-Olfactory Fusion in the Flight Behavior of Drosophila Food is often associated with odor, so olfaction is an important sense which animals use to guide them to food. Course control in insects, however, is strongly influenced by visual cues. We are testing Drosophila to see how the visual algorithms they […]

TAMMERO,L.F.*; DICKINSON,M.H.: The Pattern of Optic Flow Determines Flight Behavior in Freely Flying Drosophila While flying through its environment in search of food, a fruitfly (Drosophila) must integrate input from several sensory modalities. To study the behavioral patterns that emerge from the interactions of these sensory systems, we reconstructed three-dimensional trajectories from images taken by […]

THEOBALD, J.C.*; O’CARROLL, D.: Neural strategies that optimize motion detection in the crepuscular hawkmoth Manduca sexta Perhaps the greatest demand on visual system design occurs with the transition from day to night, since illuminance can differ by a factor of 108. For an animal to function in darker conditions, its visual system must deal with […]

FRYE, M.A.*; DANIEL, T.L.: Mechanical encoding properties of the wing hinge stretch receptor in the hawkmoth Insect flight emerges from complex interactions among patterned motor output, musculoskeletal mechanics, aerodynamic and inertial forces, and neural feedback. In the hawkmoth Manduca sexta, feedback from a wing hinge stretch receptor (SR) is crucial for the visuo-motor control of […]
