Fig. 5. Representative sequences of gape kinematics (filled circles; solid lines) and flow speed (open circles; dotted lines) as function of time (left column) and histograms of peak flow speeds observed during the experiments (right column). Data are for three individuals representing (from top to bottom) the smallest fish, an intermediate fish, and the largest fish used in this study. Note that the time axis (x-axis in left column) is identical for the three fish however, gape distance and flow speed (y-axes in left column, x-axis on right column) increase with increasing fish size. SL is standard length. TTPG is the time to peak gape.
