Fig. 6. Response latencies and success rates for escape for the three different types of tail-flips. (A) Latencies of crayfish escape after being hit by the dragonfly nymph (solid bars) or after being stimulated with a handheld probe (striped bars). During predator attacks, non-giant mediated tail-flips (Non-G) are executed with significantly longer latencies than medial giant (MG)- or lateral giant (LG)-mediated tail-flips. After stimulation with a probe, Non-G tail-flips also have significantly longer latencies than MG- or LG-mediated tail-flips. Non-G tail-flips evoked by the dragonfly nymph have significantly shorter latencies than probe-evoked ones. ^*P0.05, ^**P0.01. (B) MG- and LG-mediated tail-flips have a higher escape rate than Non-G-mediated tail-flips.
