Meeting Abstract 40.3 Monday, Jan. 5 A New Twist on Bending: Properties of the Pectoral Fin Rays of the Benthic Longhorn Sculpin, Myoxocephalus octodecimspinosus. TAFT, Natalia K.; University of Massachusetts Amherst natashak@bio.umass.edu Many benthic fishes use their pectoral fins for substrate contact, which requires a combination of stiffness for weight bearing and flexibility for gripping the substrate.

Three dimensional excape response of white spotted ratfish, Hydrolagus colliei
Meeting Abstract 39.2 Monday, Jan. 5 Three dimensional excape response of white spotted ratfish, Hydrolagus colliei. DICKSON, Juleen*; MAIA, Anabela; DOMENICI, Paolo; University of Rhode Island; University of Rhode Island; CNR-IAMC jdickson@mail.uri.edu Escape responses are vital to the survival of prey during predator-prey interactions. This study documented the kinematics of the escape responses of white spotted ratfish, […]
Gravidity degrades escape performance in threespine stickleback
Meeting Abstract 39.1 Monday, Jan. 5 Gravidity degrades escape performance in threespine stickleback MCGEE, M.D.; Univ. of California, Davis mcgee@ucdavis.edu Traits that increase reproductive success while increasing predation risk have been well documented in males, but a similar phenomenon may also exist in females. Just as males with sexually selected ornaments may experience an increased predation rate, […]
Exceptional force generation is behind dolphins swimming prowess
Meeting Abstract 39.4 Monday, Jan. 5 Exceptional force generation is behind dolphins swimming prowess FISH, Frank E*; LEGAC, Paul; WILLIAMS, Terrie M; WEI, Tim; West Chester Univ.; Rensselaer Polytechnic Institute ; Univ. of California, Santa Cruz; Rensselaer Polytechnic Institute ffish@wcupa.edu It has been a longstanding impression both within as well as outside of the scientific community that […]
Caudal fin shape modulation and control during acceleration, braking, and backing maneuvers in bluegill sunfish, Lepomis macrochirus
Meeting Abstract 39.3 Monday, Jan. 5 Caudal fin shape modulation and control during acceleration, braking, and backing maneuvers in bluegill sunfish, Lepomis macrochirus FLAMMANG, B.E.*; LAUDER, G.V.; Museum of Comparative Zoology, Harvard University; Museum of Comparative Zoology, Harvard University bflammang@oeb.harvard.edu Evolutionary patterns of intrinsic caudal musculature show that control of the dorsal lobe of the tail evolved […]
Cartilaginous vertebral columns mechanical responses to external loads and internal joint pressurization
Meeting Abstract 39.5 Monday, Jan. 5 Cartilaginous vertebral columns: mechanical responses to external loads and internal joint pressurization PORTER, ME*; LONG, JH; Vassar College; Vassar College meporter@vassar.edu While we have shown that vertebral number and centra shape are important predictors of body curvature in cartilaginous fishes during powered turns, morphological correlates predict only about 50% of body […]
Under pressure Ventilatory and suction feeding mechanics of ratfishes (Chimaeroidea)
Meeting Abstract 38.3 Monday, Jan. 5 Under pressure: Ventilatory and suction feeding mechanics of ratfishes (Chimaeroidea) FERRY-GRAHAM, LA*; SUMMERS, AP; DEAN, M; GROGAN, E; Moss Landing Marine Labs lfgraham@mlml.calstate.edu Holocephalans possess a fused upper jaw and a non-suspensory hyoid. These features, along with robust tooth plates, are thought to be associated with a durophagous foraging habit that […]
The spatial and temporal patterns of odors sampled by lobsters and crabs in a turbulent plume
Meeting Abstract 38.1 Monday, Jan. 5 The spatial and temporal patterns of odors sampled by lobsters and crabs in a turbulent plume REIDENBACH, M. A.*; KOEHL, M. A. R.; Univ. of Virginia; Univ. of California, Berkeley reidenbach@virginia.edu Odor molecules are dispersed across marine habitats by turbulent water flow, and the spatial pattern of odor concentrations in the […]
Semicircular Canal Morphology as Evidence of Sensory Adaptation to Locomotor Environment in Amniotes
Meeting Abstract 38.5 Monday, Jan. 5 Semicircular Canal Morphology as Evidence of Sensory Adaptation to Locomotor Environment in Amniotes GEORGI, Justin A; Midwestern University, Glendale, AZ jgeorg@midwestern.edu The vestibular system is a critical component of the neural control of locomotion in vertebrates. Integrated in the cerebellum with visual and proprioceptive inputs, the signals from the semicircular ducts […]
Optics of an alternative imaging system, the facial pits of Pitvipers (Viperidae Crotalinae)
Meeting Abstract 38.4 Monday, Jan. 5 Optics of an alternative imaging system, the facial pits of Pitvipers (Viperidae: Crotalinae) COLAYORI, Samantha E*; BAKKEN, George S.; Indiana State University, Terre Haute gbakken@indstate.edu Facial pits are specialized organs possessed by pitvipers (Viperidae: Crotalinae) that detect emitted thermal radiation. Optically, they apparently function like a pinhole camera eye. The image […]
