.... The substantially larger suction power in Cb04 resulted from both greater subambient buccal pressure and faster rate of buccal volume change ( Table 1 ). In Cb04, mean peak subambient pressure was approximately 5.6 times greater than that of Cb01 and nearly 3 times greater than that of Cb03, and mean peak rate...

... to the mouth are understood to be mechanically linked but the relationship between them has never been empirically determined in any suction feeder. We present the first simultaneous measurements of fluid speed and buccal pressure during suction feeding in fishes. Digital particle image velocimetry (DPIV...

... type of movements in that negative pressure inside the buccal cavity is thought to be the most important speed-limiting factor during suction. However, how buccal pressure changes with size and how this influences the speed of buccal expansion is unknown. In this paper, the effects of changes in body...

... multiple regression analyses we were consistently able to account for over 90%, and in the best model 99%, of the variation in buccal pressure among strikes using kinematic variables. Sonomicrometry shows great promise as a method for documenting movements of biological structures that are not clearly...
