Integrating the determinants of suction feeding performance in centrarchid fishes
Holzman, Roi; Day, Steven; Mehta, Rita; Wainwright, Peter (Company of Biologists, 2008-10-07)When suction-feeding vertebrates expand their buccal cavity to draw water into their mouth, they also exert a hydrodynamic force on their prey. This force is key to strike success, directly countering forces exerted by ... -
Multidimensional analysis of suction feeding performance in fishes: Fluid speed, acceleration, strike accuracy and the ingested volume of water
Higham, Timothy; Day, Steven; Wainwright, Peter (The Company of Biologists, 2006-05-03)Suction feeding fish draw prey into the mouth using a flow field that they generate external to the head. In this paper we present a multidimensional perspective on suction feeding performance that we illustrate in ... -
The Pressures of suction feeding: The Relation between buccal pressure and induced fluid speed in centrarchid fishes
Higham, Timothy; Day, Steven; Wainwright, Peter (The Company of Biologists, 2006-06-14)Suction feeding fish rapidly expand their oral cavity, resulting in a flow of water directed towards the mouth that is accompanied by a drop in pressure inside the buccal cavity. Pressure inside the mouth and fluid ... -
Spatial and temporal patterns of water flow generated by suction-feeding bluegill sunfish Lepomis macrochirus resolved by Particle Image Velocimetry
Day, Steven; Higham, Timothy; Cheer, Angela; Wainwright, Peter (The Company of Biologists, 2005-05-24)The suction-feeding fish generates a flow field external to its head in order to draw prey into the mouth. To date there are very few empirical measurements that characterize the fluid mechanics of suction feeding, p ... -
Sucking while swimming: Evaluating the effects of ram speed on suction generation in bluegill sunfish Lepomis macrochirus using digital particle image velocimetry
Higham, Timothy; Day, Steven; Wainwright, Peter (The Company of Biologists, 2005-05-11)It is well established that suction feeding fish use a variable amount of swimming (ram) during prey capture. However, the fluid mechanical effects of ram on suction feeding are not well established. In this study ... -
Timing is everything: Coordination of strike kinematics affects the force exerted by suction feeding fish on attached prey
Holzman, Roi; Day, Steven; Wainwright, Peter (Journal of Experimental BiologyCompany of Biologists, 2007-07-17)During aquatic suction feeding, the predator opens its mouth and rapidly expands its buccal cavity, generating a flow field external to the mouth. The rapid expansion of the buccal cavity produces high fluid velocities ...
