Anterior axial red muscle effort increases as water depth decreases; however, a typical swimming-like anterior-to-posterior wave of axial red muscle activity is always present, even during terrestrial locomotion, indicating gradual motor control changes. Thus, walking appears...

Here, we took a close look at the time course of these adjustments as stick insects compensate for various kinds of disturbances to load distribution. In particular, we tested whether the transition from one steady state to another...

To better understand the contribution of the jet, fins and arms to turns, the role of orientation (i.e. arms first versus tail first) in maneuvering, and the relationship between jet flow and turning performance, kinematic...

Our findings provide an important biomechanical basis for better understanding the beak as a functional tool...
