Fig. 7. The spectrum of kinematic variations among archer fish predictive fast-starts. The predictive starts required very different turns and take-off speed levels. This desired variability in the motor output should be reflected in corresponding variations in kinematics. To test this, a large number of responses (N=76) with known angles of turning and take-off speed were analyzed in detail using digital high-speed video (500 frames s^-1). The substantial variability among these responses is illustrated by showing (A) the course of chord length changes (CL), (B) the course of accumulated angle () and (C) the course of accumulated displacement (s) for all starts analyzed. Variables and how they deviate for different turning angles and take-off speed are introduced in Figs 4, 5, 6, respectively. To aid comparison, time zero is set at onset of stage 2. Background color: Stage 1 dark blue, stage 2 light blue.
