Fig. 3. The relative timing of peak pressure and peak fluid speed with respect to 20% of peak gape (dotted vertical line on the left) and 95% of peak gape (dotted vertical line on the right) for largemouth bass (black squares) and bluegill sunfish (red circles). Each value is scaled to the duration of time to peak gape where 0 is 20% and 1 is 95% of peak gape. Note that peak fluid speed follows peak gape in both largemouth bass and bluegill sunfish. The timing of peak pressure is earlier, relative to 95% of peak gape, in bass (0.51) than in bluegill (0.76).
