Fig. 11. (A,B) Average jet velocity $u$ _j, (C) L/D from average jet velocity, $u$ _j, jet period and jet diameter, (D) jet period, (E) jet frequency and average jet frequency, and (F) jet angle as functions of swimming speed. Swimming speed is in L_m s^-1, except in A. Each data point represents a jet. Jet period (D) looks discretized because of the precise timing of image exposures. In E, the open squares represent average jet frequencies, f_avg, for all sets of 3 or more jet events of individual squid at the same swimming speed. The curve in E is a parabolic fit to the average jet frequencies, f_avg. Jet angle (F) is measured in degrees subtended from the horizontal.
