Fig. 4. Variability in prey capture kinematics in bluegill striking tethered
shrimp. (A) Time to peak gape (TTPG); (B) strike initiation distance; (C)
mouth displacement; (D) maximal gape width. N=48 strikes, 12 per
fish. Strike initiation distance and mouth displacement were correlated
(R2=0.62, P<0.001) while no correspondence was
found between the other variables.
