Fig. 7. Logarithmic plot of peak prey velocities as a function of cranial length
(individual maxima of unfiltered data; filled black symbols) and the scaling
relationship (least-squares regression with 95% confidence limits) of peak
flow velocities (white circles) (from Van
Wassenbergh et al., 2006b). C. gariepinus is represented
by circles, G. typus by the triangle and C. apus by squares.
No significant interspecific differences between C. gariepinus and
C. apus were found for the residuals of peak prey velocities with
respect to the scaling relationship (ANOVA, P=0.41).
