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
/dt (A) and of
angular acceleration d
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.
