Abstract: Summary Swimming motion of Anomalocaris is studied based on hydrodynamic calculations. Anornalocaris was the largest predator in the age of the Cambrian explosion, 530 million years ago. It is considered to swim using 14 paired lateral lobes. The relating dynamics of the lobes and surrounding water is calculated by the moving particle method. Various types of swimming styles are calculated, and swimming speed and energy are discussed. As a result, a certain waving pattern for the series of lobes is calculated as the most energy saving motion.
