Fig. 5. Mean values of maximum displacement of kinematic variables for two behaviors (raking and open-mouth chewing, OMC) and three prey types (cricket, fish and worm) in Salvelinus fontinalis (N=20 for each prey type). Values are means + S.E.M. The results of an ANOVA to determine whether behaviors differ within prey are indicated within the graph. NS, P>0.05; *P<0.05; **P<0.01; ***P<0.001. Above each graph are the results of ANOVA post-hoc tests after Bonferroni correction contrasting prey-type differences within behavior. PT Rake, raking; PT OMC, open-mouth chewing.
