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

    MJP, maximum jaw protrusion; pectoral fin prot., pectoral fin protraction velocity for 50 ms prior to stopping.

    Unless stated otherwise, all values are in degrees.
