Meeting Abstract 113.2  Saturday, Jan. 7  Swimming at intermediate Reynolds numbers in water boatmen NGO, V.*; MCHENRY, M.J.; Univ. of California, Irvine; Univ. of California, Irvine vngo3@uci.edu A wide diversity of aquatic animals swim at intermediate Reynolds numbers, where both inertial or viscous forces may contribute to propulsion. Here we studied the relative importance of these forces […]

Meeting Abstract 113.6  Saturday, Jan. 7  Swimming and Feeding by Unicellular vs. Colonial Choanoflagellates KOEHL, M. *; STOCKER, R.; NICOLAU, D.; KING, N.; Univ. of California, Berkeley; MIT; Univ. of California, Berkeley; Univ. of California, Berkeley cnidaria@berkeley.edu Many aquatic protozoans are unicellular, while others form multicellular colonies. We used Salpingoeca rosetta, a unicellular choanoflagellate that can be […]

Meeting Abstract 113.1  Saturday, Jan. 7  Ontogenetic propulsive transitions from viscous to inertial flow regimes KATIJA, Kakani*; JIANG, Houshuo; COLIN, Sean P.; COSTELLO, John H.; Woods Hole Oceanographic Institution; Woods Hole Oceanographic Institution; Roger Williams University; Providence College kakani@whoi.edu Among marine organisms, the influences of flow regimes on swimming strategies are largely unknown. As an approach to […]

Meeting Abstract 113.5  Saturday, Jan. 7  Hydrodynamic function of the cephalic lobes of the cownose ray for bottom swimming stabilization FISH, Frank E*; GABLER, Molly K; BENESKI, John T; MULVANY, Samantha; MOORED, Keith W; West Chester Univ., Pennsylvania; West Chester Univ., Pennsylvania; West Chester Univ., Pennsylvania; Univ. of South Florida, Tampa ; Princeton Univ.

Meeting Abstract 113.4  Saturday, Jan. 7  Hydrodynamic Function of Dorsal Fins in Sharks MAIA, A.*; LAUDER, G.V.; WILGA, C.D.; University of Rhode Island; Harvard University; University of Rhode Island amaia@my.uri.edu Kinematic and electromyographic data from dorsal fins in sharks indicate that these structures are actively controlled during steady swimming. Here, we investigate how the two dorsal fins […]

Meeting Abstract 113.3  Saturday, Jan. 7  Flippin’ out: inverted sand dollars actively orient themselves in flow to maximize lift for righting HARDY, A.R.*; MERZ, R.A.; Swarthmore College, PA; Swarthmore College, PA arhardy7@gmail.com The fact that sand dollars are often dislodged and inverted is an inescapable consequence of living at or slightly below the sediment-water interface. Once inverted […]

Meeting Abstract 112.6  Saturday, Jan. 7  Walking With a Twist KAMBIC, Robert E*; GATESY, Stephen M; ROBERTS, Thomas R; Brown University; Brown University; Brown University robert_kambic@brown.edu Studies of tetrapod limb movement and muscle activity during steady locomotion often record data from only one side. This approach assumes that both members of a limb pair act symmetrically when […]

Meeting Abstract 112.1  Saturday, Jan. 7  Tuning of Mantle Connective Tissue to Non-Uniform Strain in the Squid Doryteuthis pealeii KURTH, J.A.*; THOMPSON, J.T.; KIER, W.M.; University of North Carolina, Chapel Hill; Franklin and Marshall College, Lancaster, PA; University of North Carolina, Chapel Hill jkurth@live.unc.edu The mantle of squid includes networks of intramuscular (IM) connective tissue fibers that […]

Meeting Abstract 112.2  Saturday, Jan. 7  Non-uniform strain in squid mantle muscle: relating the length-tension curve to in vivo muscle performance THOMPSON, J.T.*; SHELTON, R.M.; KIER, W.M.; Franklin and Marshall College; University of North Carolina; University of North Carolina joseph.thompson@fandm.edu Non-uniform strain occurs during contraction and re-expansion of the hollow, muscular mantle of squids, with up to […]
