Fig. 5. Velocity magnitude (A,C,E) and vorticity contour plots (B,D,F) during three
jets from three different adult L. pealei holding position at three
different swimming speeds. (A,B) 13 cm s-1, (C,D) 25 cm
s-1, (E,F) 56 cm s-1. Note the decrease in jet angle
subtended from the horizontal with increasing swimming speed. The magnitudes
of vorticity contours are (B,F) 3, 4, 6, 10, 15 and 20 rad s-1, and
(D) 4, 6, 10, 15 and 20 rad s-1. See explanation of contour
identification in Fig. 2. (A,B)
