Fig. 11. Plots of (A) peak fluid speed versus peak acceleration, and (B) accuracy versus the volumetric flow rate, for largemouth bass (triangles) and bluegill sunfish (circles). In A, the red symbols indicate measures of peak fluid speed and acceleration in the fish's frame of reference (FF), whereas the black symbols indicate values in the earthbound frame of reference (EF). Peak fluid speed, peak acceleration and volumetric flow rate (dV/dt) were calculated using the single maximum value for each variable for each individual. Thus, each point represents the single highest value for each individual. Accuracy was calculated by selecting the three sequences per individual that had the highest peak fluid speed and then averaging the accuracy for those three strikes.
