Fig. 7. Fluid speed compared to gape distance and ram speeds as a function of time for the two representative sequences. Fluid speed is located at a constant distance in front of the fish equal to PG. (A) A relatively slow strike (TTPG=42 ms) and (B) a fast strike (TTPG=14 ms). Note the different x-axis scales for the two feedings. Although the magnitude of speeds and duration of events is different between the two, the relative timing is similar in that peak jaw speed precedes peak fluid speed, which in turn slightly precedes peak gape. Body ram speed continually decreases throughout the strike.
