From: A methodological exploration to study 2D arm kinematics in Ophiuroidea (Echinodermata)
Intraspecific variability in arm mobility traits (PC1–2) for species O. superba including all individuals (A); without the individual illustrating reverse rowing mode (B); O. scolopendrina (C) and M. hirsuta (D). The percentages at labels show the contribution ratios and the lines with variable names represent the loading
