... within instar 7. We digitized several points that represent the movement of the coxa, trochanter–femur and tibia of the raptorial foreleg to obtain a set of kinematics including angles and angular velocities of the joint, as well as body lunge. Using the coefficient of variation, we found less stereotypy...
