Fig. 8. (A) Scatter plot of the recoil speed of the tail in stage 2 against the
mean turning rate in stage 1 (
1). Filled circles, turns with
type I wake; open circles, turns with type II wake. (B) Scatter plot of the
momentum of the vortex ring shed in stage 2 (I2) against
the recoil speed of the tail in stage 2. (C) Linear regression of
I2 against the bending amplitude
(dmax).
