Figure 5


Fig. 5. Profiles of angular speed and acceleration of archer fish predictive starts. Same starts as those analyzed in Fig. 4, silhouettes of fish shown in Fig. 3 and Fig. 11A. Open circles: response with large turn (82.1°). Filled circles: response with lesser turn (43.6°). Course of angular speed d{phi}/dt (A) and of angular acceleration d{phi}2/dt2 (B). Time zero is at start of stage 2. Background color: dark blue (stage 1), light blue (stage 2). In the lesser turn, braking at end of stage 1 was large and stage 2 angular speed approximately zero. For the larger turn angular speed was nonzero during the initial part of stage 2.
