Suction feeding kinematic data for 14 aquatic species

This dataset consists of a single .csv text file containing mouth and body kinematics, flow speeds and water fluxes into the mouths of 13 ray-finned fish species and one amphibian species during suction feeding. Mouth and body kinematics were measured by high-speed video; water flows were characterized by particle image velocimetry.Data are provided for the following species:Ambystoma tigrinum (amphibian)Polypterus endlicheriDanio rerioCarassius auratusApteronotus albifronsHemigrammus pulcherPimelodus pictusNimbochromis venustusAstronotus ocellatusPoecilia sphenopsDascyllus marginatusChromis viridisChromis pellouraLepomis macrochirusVariables reported for each specimen: Prey introduction method (wire, free or tube), morphometric and kinematic values: Max Gape, Max Jaw Protrusion distance, Time to peak gape, Gape speed, Max Flow Speed, Time to peak flow (from the time at which gape first exceeds 20% of peak gape), Total water flux into the mouth, Time to peak jaw protrusion, Jaw Protrusion Speed, Max Hyoid Depression, Time to peak hyoid depression, Hyoid depression speed, Ram Speed, Notch Angle (the angle between the upper and lower jaw bones at peak gape) and Notch Area.Background: The related study investigates inter-species variability in suction feeding kinematics: the process by which fish and other suction feeding organisms capture prey by generating a fluid flow outside of their mouths.
