This study demonstrates the sensitivity of swimming behavior and predator-escape responses of nauplii of the estuarine copepod Eurytemora affinis to sublethal doses of Cu and Cd. Behavior was generally altered at metal doses below those affecting growth rates or survival of the copepods. Swimming velocities of Cu-dosed nauplii were different from controls at all concentrations of Cu tested (10-50 micrograms/l total Cu) after 24- to 48-h exposure, whereas development rate of nauplii was significantly reduced only after 96h at 25 micrograms/l. The 96h LC50 for Cu was approximately 30 micrograms/l Cu. Naupliar swimming velocity was also affected by Cd. Reduced numbers of escape responses of naurpii to a simulated predator, another indication of increased vulnerability to predation, were observed only after 48h exposure to Cu.
