The authors found that bodies of seals had natural oscillation in pitching and rolling motions in drift dive phase by data loggers. The phenomenon is periodically oscillated at a low frequency not by flippering movement. Model experiments were performed in a circulating water channel and in a wind tunnel. The result shows clearly that the oscillatory motion of the bodies of seals during the drift dive was caused by flow induced vibration.
