Have teleost barbels evolved by the co-option of fin developmental mechanisms
Meeting Abstract 65.3 Wednesday, Jan. 6 Have teleost barbels evolved by the co-option of fin developmental mechanisms? HAWKINS, M.B.*; CRUZ, A.; STOCK, D.W.; University of Colorado, Boulder; University of Colorado, Boulder; University of Colorado, Boulder michael.hawkins@colorado.edu Understanding how complex structures can emerge repeatedly in distantly-related lineages is an important goal of evolutionary biology. A striking example of […]
Understanding Batoid Propulsion Through Artificial Structures
Meeting Abstract 65.4 Thursday, Jan. 6 Understanding Batoid Propulsion Through Artificial Structures KEMP, T*; BART-SMITH, H; MOORED, K; University of Virginia; University of Virginia; Princeton University tk4b@virginia.edu The manta ray (Manta birostris) is known for its swimming maneuverability and it is thought that these animals have a high long range cruising efficiency; both of these qualities are […]
The effects of head shape on drag and lift during subsurface sand-swimming
Meeting Abstract 65.2 Thursday, Jan. 6 The effects of head shape on drag and lift during subsurface sand-swimming MALADEN, RD*; DING, Y; UMBANHOWAR, PB; MASSE, A; GOLDMAN, DI; Georgia Tech, Atlanta; Georgia Tech, Atlanta; Northwestern Univ., Illinois; Georgia Tech, Atlanta; Georgia Tech, Atlanta Dingyang@gatech.edu Morphological adaptations such as a sharp wedge-shaped head are hypothesized to reduce sand-swimming […]

Meeting Abstract 65.3 Thursday, Jan. 6 Importance of wrist rotation for high performance terrestrial locomotion of a sea turtle inspired physical model MAZOUCHOVA, N.*; UMBANHOWER, P.; GOLDMAN, D.I.; Georgia Institute of Technology; Northwestern University; Georgia Institute of Technology nmazouch@gatech.edu To reach the ocean after hatching, juvenile sea turtles use their flippers to traverse a beach environment typically […]
Ground Effects on Undulating Fins Robotic Modeling of Stingray Locomotion
Meeting Abstract 65.5 Thursday, Jan. 6 Ground Effects on Undulating Fins: Robotic Modeling of Stingray Locomotion BLEVINS, E.L.*; LAUDER, G.V.; Harvard University; Harvard University eblevins@fas.harvard.edu Benthic fish are specialized for life at the boundary between the fluid and solid world. Many species use the substrate for a direct boost to propulsion, from pelvic fin punting by skates […]
Biorobotic analysis of the functional significance of fish tail shapes
Meeting Abstract 65.6 Thursday, Jan. 6 Biorobotic analysis of the functional significance of fish tail shapes LAUDER, George*; WITT, Chuck; ANDERSON, Erik; Harvard Univ.; Grove City College; Grove City College glauder@oeb.harvard.edu Fish vary greatly in tail shape. The homocercal (symmetrical) shape characteristic of most teleost fishes, and the heterocercal (asymmetrical) shape that is present in most shark […]
Rates of hybridization, introgression, and formation of chimaeric lineages in Darters
Meeting Abstract 65.4 Friday, Jan. 6 Rates of hybridization, introgression, and formation of chimaeric lineages in Darters. KECK, BP; University of Tennessee bkeck@utk.edu It is currently accepted that hybridization and introgression can influence the evolutionary trajectory of a lineage and affect patterns of diversification. Whether it is the capture of a heterospecific mitochondrial genome or the formation […]
