TRIGGERING ESCAPES IN COPEPODS: A REVIEW
image
Preyed upon by a wide variety of predators from other copepods to whales, the success of any individual copepod is highly dependent on its ability to avoid being eaten. Predator evasion strategies include small size, transparency, vertical migration, bioluminescence and an effective escape behavior. Recently, new techniques have been developed to study physiology and behavior in these small crustaceans. In this talk, we will review the state of knowledge in this area. We will discuss the types of controlled stimuli that have been used in different laboratories to trigger escape reactions, the different features observed in escapes, and the ways in which the escape behavior is modulated by the type and strength of stimulus. Comparisons will be made of escape behaviors triggered by artificial stimuli and those triggered by predators. Finally, we will review species-specific patterns in copepods escape behavior and relate these to our understanding of the copepods’ nervous system.
