Fig. 9. Filament sharpness along the antennule. Filament sharpness is defined as the ratio of the maximum concentration, C (normalized by the source strength, C_source) to the spatial distance from the edge of the filament to the point of maximum concentration, W (normalized by the source diameter, D_source). Tracks in wave-affected flow are shown in bars with black diagonal stripes (mean of all four wave-affected flow tracks in black bar), and tracks in unidirectional flow are shown in bars with gray diagonal stripes (mean of all three unidirectional flow tracks in gray bar). Values are means ± S.D. The number of flicks (N) for each track is shown in parentheses above the bar.
