Fig. 5. Distribution of all strikes and relative positions of dragonfly nymphs during attacks that evoked the three different types of tail-flips. Black circles indicate the position of the center of the labium on the crayfish's body for each strike and type of escape response. A schematic of the frontal part of the labium is shown to illustrate the size relationship (bottom left). Arrows around the crayfish demonstrate the relative position of the dragonfly nymph when the attacks were delivered.
