Fig. 2. Two three-dimensional examples of male ostracod displays, showing luminescence, swimming patterns and speeds. (A) Close-up of the first seven pulses of a display. (B) Example of an entire display. In the stationary phase males swim slower than when in the helical phase (see also Table 2, Fig. 4D and Fig. 5). Data points are every 67 ms. Large blue circles indicate the location of each luminescent pulse. The color of the small spheres indicates the swimming speed of the ostracod at that given point in time. The z-axis is in centimeters from the top of the tank, the x-axis is the distance from the left side of the tank, and the y-axis is the distance in depth from the first data point.
