Figure 7


Fig. 7. Model of four luminescent display trains produced by a single Vargula annecohenae, based on the interpulse intervals, interpulse distances, pulse intensities, and swimming patterns of males displaying in the lab (Tables 1 and 2). The first three pulses in each train are the stationary phase; the remaining pulses are the helical phase. Black dots indicate the location of the light pulses (their size corresponds to relative intensity) and the faint lines indicate swimming trajectory (only the third display train shows the stationary phase swimming pattern). Once a male reaches the top of the train, it swims rapidly downward without spiraling, and then commences displaying again.
