Meeting Abstract 29-7 Saturday, Jan. 4 14:45 – 15:00 Ultrafast Finger Snap is Mediated by a Frictional Skin Latch ACHARYA, R*; CHALLITA, EJ; BHAMLA, MS; Georgia Institute of Technology racharya33@gatech.edu http://bhamla.gatech.edu The snap of a finger is a ubiquitous motion that has been seen across cultures and times. Using high-speed imaging, we analyze finger snap dynamics for […]

The Cone Snail Strikes Back A Biomechanical Study of an Ultrafast Prey Capture
Meeting Abstract 29-8 Saturday, Jan. 4 15:00 – 15:15 The Cone Snail Strikes Back: A Biomechanical Study of an Ultrafast Prey Capture JAN, I*; SANGHA, G; SCHULZ, JR; Occidental College; Occidental College; Occidental College tjan@oxy.edu While predatory cone snails have been extensively studied for their venom properties, their ultrafast prey capture mechanism remains relatively recondite. The fish-hunting […]
Temperature dependence of elastic recoil mediated by a mechanical advantage latch
Meeting Abstract 29-4 Saturday, Jan. 4 14:15 – 14:30 Temperature dependence of elastic recoil mediated by a mechanical advantage latch MENDOZA, E*; OLBERDING, J/P; AZIZI, E; University of California, Irvine emendoz7@uci.edu Changes in temperature alter muscle kinetics and these effects can be observed during whole-organism performance. Some organisms use elastic recoil, which is far less sensitive to […]
Limits and Losses the Power of Recoiling Biological Springs
Meeting Abstract 29-1 Saturday, Jan. 4 13:30 – 13:45 Limits and Losses: the Power of Recoiling Biological Springs OLBERDING, JP*; ILTON, M; CROSBY, AJ; AZIZI, E; University of California, Irvine; Harvey Mudd College; University of Massachusetts, Amherst; University of California, Irvine olberdij@uci.edu Many organisms use springs to actuate extremely fast movements because they can bypass the power […]
How does Morphology Affect Jumping Kinematics of Click Beetles
Meeting Abstract 29-5 Saturday, Jan. 4 14:30 – 14:45 How does Morphology Affect Jumping Kinematics of Click Beetles? BOLMIN, O*; ALLEYNE, M; WISSA, AA; University of Illinois at Urbana-Champaign; University of Illinois at Urbana-Champaign; University of Illinois at Urbana-Champaign obolmin2@illinois.edu http://bamlab.mechse.illinois.edu/ When unconstrained and from an inverted position, click beetles (Coleoptera:Elateridae) fold their body extremely rapidly to […]
Evidence of power amplification and thermal robustness in salamandrid feeding mechanisms
Meeting Abstract 29-3 Saturday, Jan. 4 14:00 – 14:15 Evidence of power amplification and thermal robustness in salamandrid feeding mechanisms STINSON EASTERLING, CM*; SEIS, C; DEBAN, SM; Northwest University; University of South Florida; University of South Florida charly.easterling@gmail.com https://easterlingc.wixsite.com/easterlingc Tongue projection is often used by salamanders to feed on land. Many plethodontid salamanders are known for high-powered, […]
Beyond power amplification new insights from latch-mediated spring actuation (LaMSA)
Meeting Abstract 29-2 Saturday, Jan. 4 13:45 – 14:00 Beyond power amplification: new insights from latch-mediated spring actuation (LaMSA) LONGO, SJ*; COX, SM; AZIZI, E; ILTON, M; OLBERDING, JP; ST.

Why Hatchling Painted Turtles Overwinter in Their Nest
PACKARD, M.J.*; PACKARD, G.C.: Why Hatchling Painted Turtles Overwinter in Their Nest We placed hatchling painted turtles (Chrysemys picta) individually into pint-volume canning jars containing damp soil or artificial pond water and then exposed the animals to 4oC in a simulated hibernation lasting 70 days. Our goal was to gain new insight into why baby […]
Turtle Phylogeny Insights from a Nuclear Gene
KRENZ, J.G.*; JANZEN, F.J.: Turtle Phylogeny: Insights from a Nuclear Gene Turtles have a long and successful evolutionary history, dating back over 200 million years. Relationships among many extant turtle families remain unclear, despite a large data set containing morphological characters as well as DNA sequences from the mitochondrial cytochrome b and 12S ribosomal DNA […]
New perspectives on the origin(s) of marine turtles
Parham, J.F.: New perspectives on the origin(s) of marine turtles Because they share a large number of morphological characters, living marine turtles (Chelonioidea) are thought to have evolved from a single ancestor. All chelonioids share paddle-like limbs, a reduced shell, and peculiar arterial perforations of the braincase. However, comparative studies of distantly related clades that […]
