Fig. 9. Histogram of the ratio of jet structure length to jet diameter, L_j/D, based on the maximum length of each jet in the field of view visualized for all squid jets in which the squid was holding position (116 jets). The black section of each bar represents measurements that appeared to be good estimates of the total length of the jet structure. The white section of each bar represents measurements considered to be underestimates because the jet structure extended out of the field of view or the squid swam at a slight angle to the laser plane. Bin centers start at 2 and bin width is 2.
