Figure 13


Fig. 13. Archer fish C-type escapes and predictive starts follow an identical temporal pattern. The histograms show how the timing of the maximum speed and acceleration attained was distributed among the predictive starts (red columns) and the escapes (blue columns). Time zero is at onset of stage 2. Distribution of timing of (A) maximum linear speed, (B) maximum linear acceleration, (C) maximum angular speed, and (D) maximum angular acceleration. A MANOVA detects no significant difference among these timing parameters (P=0.393). Respective bin sizes are: 10 ms (A,B), 2 ms (C), 5 ms (D). Total counts in the respective histograms were for the predictive starts N=69 (A), N=59 (B), N=72 (C), N=68 (D), and for the escapes N=33 (A), N=30 (B), N=31 (C), N=31 (D).
