... of suction feeding ability in two members of Centrarchidae, the largemouth bass ( Micropterus salmoides ) and bluegill sunfish( Lepomis macrochirus ). We present the first direct measurements of maximum fluid speed capacity, and we use this to calculate local fluid acceleration and volumetric flow rate. We...

... of protraction. Thus, pectoral fin area appears unlikely to be the primary constraint on braking performance for this particular task. We studied the bluegill sunfish Lepomis macrochirus Rafinesque, a member of the freshwater family Centrarchidae. The fish were collected in California, USA and were...

... that a hydromechanical stimulus detected by the cephalic lateral line system in two sunfishes (Centrarchidae) can be the sole determinant of a strike trajectory. The response occurs without reinforcement and appears to be an unconditioned response. Green sunfish ( Lepomis cyanellus Rafinesque) and largemouth bass...
