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.
