Fig. 11. (A,B) Average jet velocity
j, (C)
L/D from average jet velocity,
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 Lm 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, favg, 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, favg. Jet angle (F) is
measured in degrees subtended from the horizontal.
