Introduction to the Symposium—Unsteady Aquatic Locomotion with Respect to Eco-Design and Mechanics

fish, frank e; domenici, paolo;

The importance of unsteadiness in the aquatic environment has come to the forefront in understanding locomotor mechanics in nature. The impact of unsteadiness, starting with control of posture and trajectories during aquatic locomotion, is ultimately expressed in energy costs, morphology, and fitness. Unsteadiness from both internal and external perturbations for aquatic animals is important at scales ranging from micro to macro to global.
