Undulatory swimming

Definition

Undulatory swimming is a mode of locomotion characterized by wave-like motions of the body, typically seen in aquatic animals like fish and some amphibians. This type of movement allows organisms to efficiently propel themselves through water by generating thrust through the undulation of their bodies, often combined with fin or tail movements. The biomechanics of undulatory swimming have inspired the design of bio-inspired propulsion systems in robotics, mimicking nature's efficient methods of movement.
