摘要

Planktonic copepods exhibit rapid escape behavior in response to hydrodynamic distur- bances. Small disturbances of brief duration were produced by a piezoelectric transducer moving a small cylinder. The escape responses of free-swimming adult males and females of the copepods Acartia tonsa and A.lilljeborgii were recorded using high-speed video and quantified using comput- Erized motion analysis techniques. Response latency, swimming speed, acceleration and turning rate During escape behavior were measured. Acartia spp. typically respond within 4 ms to a hydro- Dynamic disturbance with multiple power strokes of the swimming legs.
