Fig. 6. With no immediate competition at the point of catch fish arrive very slightly after the prey has landed. (A) Actual arrival times at the point of catch. The histogram shows the distribution of actual arrival times with respect to prey impact (which occurs at time t=0). In this diagram t>0 means that the fish arrives after the prey has landed, t<0 means that fish arrives before prey. (B) Histograms of arrival times expected on the basis of the respective take-off speed and supposing that the fish would simply continue to move with this speed. This distribution corresponds well to that of actual arrival; however, systematically larger expected than actual arrival times show that take-off speed was chosen slightly too slow and that later speed corrections were made. Expected and actual times were sampled at intervals of 0.02 s and accumulated in histograms that were normalized so that the total frequency equalled 1. All N=90 responses, ticks on ordinate indicate 10% frequency.
