Relationships of lateral displacement of the tail tip with speed. Lateral displacement is measured as the lateral distance of the tail tip relative to the pelvic girdle, as measured on the left side of the body. Data points are means for each individual. Error bars are s.e.m. Regression analysis demonstrates a significant negative relationship of lateral displacement of the tail tip with speed when the tail is unaltered (P = 0.042). Lateral displacement of the tail is significantly reduced when the tail is restricted, with no relationship to speed.
