Parallel evolution of shape divergence in the shells of freshwater turtles inhabiting different flow regimes
Meeting Abstract 33.4 Thursday, Jan. 5 Parallel evolution of shape divergence in the shells of freshwater turtles inhabiting different flow regimes RIVERA, G*; DAVIS, JN; GODWIN, JC; ADAMS, DC; Iowa State University; Tuskegee University; Alabama Natural Heritage Program; Iowa State University grivera@iastate.edu Parallel evolution, the process by which similar selection pressures produce repeatable effects across disparate taxa, […]
Limitations to swimming speed in drag based aquatic systems
Meeting Abstract 33.1 Thursday, Jan. 5 Limitations to swimming speed in drag based aquatic systems CLEMENTE, CJ*; RICHARDS, CT; Harvard University; Harvard University clemente@rowland.harvard.edu Within terrestrial systems, the fastest sprinters are neither the largest, nor the smallest, but are intermediately sized. The initial increase in speed is because stride length increases more rapidly than stride frequency decreases […]
How sculpin pectoral fin morphology changes with demand across habitat transitions
Meeting Abstract 33.2 Thursday, Jan. 5 How sculpin pectoral fin morphology changes with demand across habitat transitions KANE, Emily A.*; HIGHAM, Timothy E.; University of California, Riverside; University of California, Riverside ekane001@ucr.edu Aquatic organisms that occupy high-flow habitats often display traits associated with decreased drag and increased friction with the substrate. Sculpins (Scorpaeniformes: Cottoidea) have transitioned from […]

Pharyngeal jaw function in three cyprinid fishes
Meeting Abstract 32.3 Thursday, Jan. 5 Pharyngeal jaw function in three cyprinid fishes GIDMARK, NJ*; TARRANT, JC; BRAINERD, EL; Brown University njg@brown.edu Cyprinids process food with highly specialized pharyngeal jaws. These jaws bear blade-like teeth in herbivores, molariform teeth in molluscivores, and heterodont dentition in omnivores. We studied food processing in grass carp (Ctenopharyngodon idella; herbivore), black […]
On the jaws of lamniform sharks
Meeting Abstract 32.2 Thursday, Jan. 5 On the jaws of lamniform sharks DEAN, Mason*; HUBER, Dan; GOO, Brian; DANOS, Nicole; SHIMADA, Kenshu; SUMMERS, Adam; MPI; UT; UCI; UCI; DePaul; FHL/UW mason.dean@mpikg.mpg.de The 15 species of lamniform sharks vary widely in feeding niche, including piscivores, megacarnivores and filter feeders. The functional morphology of their feeding apparatus is difficult […]
Morays de-couple feeding and respiration via a parabranchial pouch
Meeting Abstract 32.1 Thursday, Jan. 5 Morays de-couple feeding and respiration via a parabranchial pouch MEHTA, Rita/S*; POLLARD, Rachel/E; Univ. of California, Santa Cruz; Univ. of California, Davis rsmehta1123@gmail.com Moray eels are the only reported example of a teleost where the behaviors of feeding and respiration are decoupled. Moreover, the evolution of a specialized prey capture and […]
