Swimmers in nature use body undulations to generate propulsive and maneuvering forces. The body shape of the swimmer and its motion kinematics act in concert to determine these forces and the associated energy expenditure. I will present our recent work on the fluid-structure interaction problem that underlies these questions, using a flexible thin plate as a minimal model of bio-inspired undulatory swimmer. In a second part of the talk I will discuss several mechanisms of swimming mechanisms that we have explored using experiments with real fish, including collective dynamics.
