Appendix 4—figure 1. The time it takes to reach prey for successful fast capture swims does not strongly depend on the distance from which these are executed.

Points are coloured according to the classification in capture speed as in Figure 4 Yellow: fast-capture swims, cyan:slow capture swims. In all groups the time to reach prey is longer for the capture swims that were clustered as slow, while for fast-captures swims the timing is more compactly distributed below 0.15 s. Maintaining such timing would require adjusting capture speed with prey-distance. It appears that LF (B) can regularly do this even for prey distances beyond 0.4 mm, where successful hunt episodes from NF, DF (A,C) are rare. The overall distributions of time-to-reach prey match the ranges of maximum gape-timing reported in Mearns et al., 2020, and therefore support the hypothesis that time of maximum gape is synchronized to the time the larva reaches/hits prey during a capture swim.
