Figure 2.
Exemplar for the interaction between an approaching larval fish (3 dph) and an escaping copepod (late copepodite, CV stage) following early detection of the approaching predator by the prey. (a) Overlaid images of copepod escape trajectory from start (t0, green triangle) to initial escape position (t10, yellow circle) to final escape position (tF, red square), with fish approach and copepod escape measurements listed, as defined in figure 1 (see also Material and methods). (b) Escape speed of the copepod computed at 2-ms intervals. (Online version in colour.)
