From: A methodological exploration to study 2D arm kinematics in Ophiuroidea (Echinodermata)
Boxplots of sinuosity (A), angle (B), slip angle (C), and disc displacement (D) for O. superba, O. scolopendrina and M. hirsuta, in arms 1–5 and frames 2–5. The boxplots provide the summary of the data as minimum, first quartile, median, third quartile and maximum. The diamond-shaped markers show the outliers. For the meaning of "frame" see Fig. 3
