Figure 9


Fig. 9. Matching the fast-start to the required angle of turning. The best predictor of turn size in predictive starts (red circles) as well as in escapes (blue circles) was how much the fish's body was bent by the end of stage 1. This is quantified here as the minimum chord length (CL) achieved (see Fig. 4 for introduction of CL). Slope and intercept of the regression lines (predictive starts, red: r2=0.749, P<0.0001, N=76; escapes, blue: r2=0.473, P<0.0001, N=34) were not different between escapes and predictive starts (P>0.05).
