Fig. 3. Profiles of speed (A) and scaled speed (B) measured along the centerline
transects for three different feedings of the same individual. (A) The
magnitude and shape of the velocity profile are affected both by variation in
peak gape (PG) and time to peak gape (TTPG). (B) Data for
the same three feedings as in A, in addition to 13 others from this
individual, after scaling. Spatial distances are scaled by gape at the time of
the velocity measurement. Fluid speeds are scaled by the fluid speed measured
at a distance of 
gape (FSgape) in front
of the fish. A polynomial fit to the data of all 16 feedings is shown as a red
broken line (r2=0.986). Error bars represent the
S.D. of the residuals about the fit line and are shown
at every 0.1 scaled distance. The equation for speed along the centerline from
the theoretical model of Muller
(1982) is shown as the blue
broken line (r2=0.986). Note that although variations in
PG and TTPG have a significant effect on the absolute values
of speed, the scaled profiles for all transects are very similar to one
another.
