Fig. 11. The spectrum of kinematic variations among archer fish C-type escape
starts. A large set of responses (N=34, black lines) from the same
group used in characterizing the predictive starts was analyzed in detail
using digital high-speed video (500 frames s-1). The substantial
variability is illustrated by showing all courses of chord length changes
(CL; A), accumulated angular changes (
; B) and of accumulated
displacement (s; C). Time zero (dotted vertical line) is set at onset
of stage 2. Variables and how they deviate for wide and narrow turns as well
as for different take-off speed are introduced in Figs
4,
5,
6. The courses of the
predictive starts recorded in the same group
(Fig. 7) are shown for
comparison (gray lines).
