The swimming speed and change of position of each individual in a school were measured in a water tank to discuss the swimming behavior, such as continuity of swimming speed , response time lag ofmotion and spatial distribution probability. The swimming speed lost its correlation in 2.0 seconds. The time lag for response was distributed within 0 .5 to 5. 0 seconds and about 20% of total combinations showed a 0.5 second response, which coin cided with the latent period of swimming motion that

The authors attempted to calculate them using the correlation coefficient of swimming speed. The data used in these analyses were as the same ones that had reported previousiy1), in which the relations between deformation and swimming speed of school have been discussed. The swimming speed were rearranged again discriminating each individuals.
