TL;DR: The model indicates that the pressure gradient in front of a fish that is feeding by suction, associated with the gradient in water velocity, results in a force on the prey that is larger than drag or acceleration reaction, even when other features of the suction flow are held constant.

TL;DR: A multidimensional perspective on suction feeding performance is presented and it is suggested that species that generate high fluid speeds in the earthbound frame of reference will commonly exhibit small mouths and a high capacity to deliver force to buccal expansion, while species that ingest a large volume of water and generate high volumetric flow rates will have larger buCCal cavities and cranial expansion linkage systems that favor displacement over force delivery.

TL;DR: Comparison of the time-resolved fluid velocity measurements to gape kinematics demonstrate that peak fluid speed occurs simultaneously with 95% of peak gape, showing that the bluegill maximizes nearly simultaneously both the generated forces and size of the region over which these forces act.

TL;DR: Several variables of locomotor performance related to prey capture are discussed, new data on the relationship between locomotor and feeding morphology in fishes are presented, and the evolution of prey capture in cichlid fishes is discussed, to outline some future directions for research.

TL;DR: The scaling between peak buccal pressure and peak fluid speed at the mouth aperture differed in the two species, supporting the recent conclusion that species morphology affects this relation such that a general pattern may not hold.
