Fig. 3. (A) Representative kinematic profile of buccal cavity variables and pressure to show the details of the expansion phase during suction feeding in Micropterus salmoides. Post., posterior; Ant., anterior. (B) Buccal cavity area plotted against time for the same sequence as in A. (C) Rate of change in buccal area for the same sequence as in A. (D) Rate of change in buccal area divided by buccal area for the same sequence as in A. Time zero (t0, solid vertical line) represents the time of peak subambient pressure. Note the very early time of peak subambient pressure.
