Figure 1


Fig. 1. A schematic diagram of the measurements made to characterize strike accuracy. The boundary, which surrounds the ingested volume of water in lateral view, shows a typical shape for a largemouth bass (dark line). The lighter boundary shows a typical shape of the ingested volume of water for a bluegill sunfish. The aspect ratio of the parcel of ingested water was calculated from its length and height. Strike accuracy was determined by measuring the distance from the center of the parcel (COP) to the center of mass of the prey (COM) and then dividing this by the distance between the COP and the boundary of the ingested volume, intersecting the COM of the prey. The vertical (Ay) and horizontal (Ax) components of accuracy were determined by measuring the distance between the COM of the prey and each axis.
