Values are F (P). Variables beginning with t,Vx, l and x are durations, forward velocities,anatomical length and length along the x axis, respectively. Subscripts m and s indicate the moving and static portions within a cycle,respectively. Prefix Δ indicates change within one cycle. For the ANOVA of perch inclines at 1.6 cm diameter, the d.f. for lm, xm, ls and xs is 2,6
