Figure 4 in Metamorphosis and evolution of feeding behaviour in salamanders of the family Plethodontidae

Figure 4. Bar graphs of gape cycle durations and lunge distances of four species of larval plethodontids showing differences. Bars sharing a letter are not significantly different from one other. G. porphyriticus (abbreviated Gp) has a significantly longer gape cycle than D. quadramaculatus (Dq) and P. ruber (Pr). D. quadramaculatus lunges significantly farther than G. porphyriticus and P. ruber. E. wilderae (Ew) is not significantly different from other species either with regard to gape cycle duration or lunge distance. Number of feedings (n) is given for each species.
