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.
