RESULTS
The acceleration data for 7 leaping and 18 burst swimming behaviors in 2010 and 3 gliding and 8 burst swimming behaviors in 2011 were recorded for 13 tagged flying fish (Table 1). Six of the 10 flying fish in 2010 and the 3 flying fish in 2011 that were pursued by the black tip sharks flew out of the aquarium and landed on the ground. It was possible to retrieve all acceleration data loggers used in the experiment. The flying fish also showed burst swimming to escape from the black tip reef shark under water without successful gliding. In order to compare the effects of the position of the data loggers on the gliding behavior of the fish, we compared pitch angle, amplitude of fluctuation in swaying acceleration, stroke cycle frequency and acceler ation duration between the 2010 and 2011 experiments (Table 2). No significant differences were ob served, indicating that the position of data logger attachment did not affect gliding behavior of the fish. We thus pooled data for the pitch angle, amplitude of fluctuation in swaying acceleration, stroke cycle frequency, acceleration duration and amplitude of fluctuation in surging acceleration and compared those values between when flying fish were either successfully taking off or swimming fast to escape from the sharks. The amplitude of fluctuation in swaying acceleration and stroke frequency seemed to be similar between the underwater
