Quicktime	Slow speed playback of the vortex wake of the bluegill pectoral fin during a turn. This wake has been generated on the opposite side as the stimulus provoking the turn and the vortex jet is oriented parallel to the body: . Drucker and Lauder (2001) J. Exp. Biol. 204: 431-432.

Quicktime	Vortex wake of the pectoral fin in a bluegill (Lepomis macrochirus) visualized with digital particle image velocimetry in ventral view. This video shows two fin beats during steady swimming followed by a beat as the bluegill initiates a turn away from the stimulus. Drucker and Lauder (2001) J. Exp. Biol. 204: 431-432.

Quicktime	Slow speed playback of the vortex wake of the bluegill pectoral fin during a turn. This wake has been generated on the same side as the stimulus provoking the turn and the vortex jet is oriented perpendicular to the body. Drucker and Lauder (2001) J. Exp. Biol. 204: 431-432.

Quicktime	Vortex wake of the pectoral fin in a bluegill (Lepomis macrochirus) visualized with digital particle image velocimetry in ventral view (see Drucker and Lauder (2001) J. Exp. Biol. 204: 431-432). This video shows two fin beats during steady swimming followed by a stronger beat as the bluegill initiates a turn toward the stimulus (to its right).

Quicktime	Pectoral fin locomotion in a bluegill (Lepomis macrochirus) visualized from posterior and showing the fin beating through a horizontal laser light sheet. See Drucker and Lauder (1999) J. Exp. Biol. 202: 2393-2412.

Quicktime	Pectoral fin locomotion in a bluegill (Lepomis macrochirus) showing simultaneous lateral and ventral views. See Gibb, Jayne, and Lauder (1994) J. Exp. Biol. 189:133-161.

Quicktime	Time sequence of vorticity and water velocity vectors resulting from use of the left pectoral fin during braking in bluegill sunfish. Data were obtained using DPIV and the bluegill was trained to feed in a location that resulted in the left pectoral fin wake intersecting the laser light sheet. The orientation of the bluegill matches the light video above. As braking occurs, a high-velocity jet of water is directed anteriorly as counterrotating centers of clockwise and counterclockwise vorticity develop (Drucker and Lauder, 2002: Integ.Comp. Biol. 42:997-1008).

Quicktime	Light video of a bluegill sunfish using its pectoral fins to reduce forward momentum as it feeds on a small piece of worm. The pectoral fins move anterolaterally (Drucker and Lauder, 2002: Integ.Comp. Biol. 42:997-1008).
