The means and their standard error in arm angle, slip angle, and sinuosity in total trials of O. superba (AC), O. scolopendrina (DF), and M. hirsuta (GJ). In plot J, the outliers (extensive folding of arms 1 and 5 in two individuals of M. hirsuta) are excluded for a better resolution of the line disparity. The X-axis implies a full cycle of arm movement which was split into four equal intervals, yielding five frames
