SD indicates 1 standard deviation.

No comparisons were significant after sequential Bonferroni adjustment. Degrees of freedom were based on the number of subjects for each species.

Data were collected for only one subject during horizontal locomotion. Thus the standard deviation and degrees of freedom are calculated based on the number of experiments for that subject.
