Fig. 4. Velocity magnitude (A,C,E) and vorticity contour plots (B,D,F) during three jets from three different adult L. pealei holding position at approximately the same swimming speed. (A,B) 25 cm s^-1, (C,D) 26 cm s^-1, (E,F) 27 cm s^-1. The magnitudes of vorticity contours are (B) 4, 6, 10, 15 and 20 rad s^-1, and (D,F) 3, 4, 6, 10, 15 and 20 rad s^-1. See explanation of contour identification in Fig. 2. (A,B) t=0.3 s, t/ ${Delta}$ t_j=0.5, (C,D) t=0.3 s, t/ ${Delta}$ t_j=0.5, and (E,F) t=0.7 s, t/ ${Delta}$ t_j=1.2.
