  • Values are means ± s.e.m; N=19 for intact and N=18 for reduced pectoral fin area. The F values from two-way ANOVAs, which were performed separately on each variable.

    P, propulsion only; B, braking only; Vmax, maximum velocity; Vavg, average velocity; VMJP, velocity at max jaw protrusion; MJP, maximum jaw protrusion; Accelmax, maximum acceleration; Decelmax, maximum deceleration; DecelMJP, deceleration at maximum jaw protrusion; pect., pectoral fin; pelv., pelvic fin; med., median fin.
