Fig. 3. Representative pressure traces from three species. Pressure magnitude and
timing differed among the species used in this study. For clarity, only L.
macrochirus, M. salmoides and P. nigromaculatus are illustrated
here. Pressure profiles and magnitudes are similar to those measured in other
studies of the same species (Grubich and
Wainwright, 1997; Lauder,
1983b; Lauder et al.,
1986; Norton and Brainerd,
1993; Sanford and Wainwright,
2002).
